    The adventure equipment of choice for improving your body's performance across a wide range of activities.

    CW-X Men's Full-Length Conditioning Tights belong to a new class of high-performance equipment known as conditioning wear. This clothing is engineered to provide a host of benefits to your body, including key muscle group support, increased endurance, shorter recovery times after exercise, lactic acid buildup prevention, and precise knee joint alignment. Established in Japan in 1991, CW-X based its designs on the human body's unique motion during exercise. Perfect for running, cycling, climbing, and snowsports, Conditioning Tights work by combining two unique zones of stretch material. The body is constructed from a Coolmax and 4-way stretch Lycra blend, providing targeted muscle support and impressive moisture-wicking properties. The key to the Conditioning Tights, however, lies in the 2-way stretch Conditioning Web that encircles the knee joint and key muscle groups. While stretching longitudinally, this web holds muscles securely in place laterally, reducing vibration and increasing comfort. Flat seam stitching throughout ensures chafing is never a problem.

    Didn't know how much I loved these...

    • Familiarity: I've used it several times
    • Fit: True to size
    • Size Bought: Large
    • Height: 6'
    • Weight: 209lbs

    I picked up a pair of these quite a while back for running and biking. They had mostly sat in a drawer until my ski trip (first ever) this past week. On a whim I tossed them in my bag and I'm sure glad I did. The first day I wore a typical baselayer under my ski pants. The second day I woke up with sore legs, and thought hey let's try the compression tights! The minute I put these on I felt relief and much stronger in my legs. I wore them for the rest of my ski days (3 days total). By the end they were a bit funky but my legs made it through the trip and I attribute a big part of that to these tights! I would definitely recommend these bad boys to anyone looking to support leg endurance.

    awesome baselayer

    • Familiarity: I've put it through the wringer
    • Fit: True to size

    i know it's "made" for running but i use it for skiing. soon as i put it on it, it gave me the tightness around my muscles. it gives me more confidence than anything since i know there's more stability provided with the pants on. i also use them sometimes to play basketball.

    i have worn them many times over the last 5 years and they have held together nicely without tearing or stretching out. i usually wash them after each use and just air dry it.

    i haven't tried other compression pants so i can't compare but these feel great when i play sports and it keeps me warm enough during skiing.

    i'm 5'9" and 163lbs and use a Medium. i don't have gladiator legs but they're thicker than the average guy and they fit perfectly. just gotta get down and squeeze into them. if you don't have to squeeze into them, they're too big.

    Great under Don Joy knee brace.

    • Familiarity: I've used it once or twice and have initial impressions
    • Fit: True to size

    These are super sweet underneath my Don Joy knee brace, i always have issues with my brace sliding down during a ski day, but with these honestly they helped so much. I am 5'9" and 145 pounds, and a small fit me very good, they are warm, and keep the warm in while skiing. HIGHLY RECOMMENDED for Knee support.

    Fit and Function

    • Familiarity: I've used it several times
    • Fit: True to size

    I am 5'10, 190lbs. right at the top end of Med. and they fit really well. They have preformend good in cold temps so far as well (above 20 dagree's)

    Awesome to help prevent fatigue / soreness

      I have used these tights for alpine skiing and really can say they have made my legs fatigue a lot less. After a long run, top to bottom, my legs sometimes feel a little tired but never sore like they were before wearing the tights. I just don't get that burn from working the quads, calves, and hamstring after a long hard run.

      I have heard of people wearing them after events to help recover and prevent lactic acid build up but I've never tried them after, only during...

      They are also great if you get sore from standing on cold concrete for a lengthy time. I have worn them to watch many a winter little league game when it's cold on the bench but standing makes you sore, these tights really help.

      They are not thermals so if you're in extreme cold, wear an extra layer. if you're warm like me, they do just fine! Be sure to use the tie at the top to keep them from sliding down as nobody likes that "plumber action" :-)

      I have had 2 different sizes of tights and like the smaller size more. If you're in between sizes go smaller as they seem to provide even more support and relief when they're a little tighter.

      Let 'er rip

        On the 5th time wearing these tights as I was pulling them on, they tore through the material (not along the seem, but the material itself). I double checked that I had the right size for my height and weight (which I did) and I double checked that I was putting them on the way the instructions stated (which I was). I called Backcountry and they immediately sent out a replacement pair of tights. In the 4 times I had worn these tights before they ripped, I had done speed work and an 8-miler in 30-40 degree temps without any chaffing. They felt great. I look forward to testing this replacement set and am hoping that it was just an anomoly. In any case, I was extremely impressed with

        replaces knee supports

          I had arthroscopic operations on both knees and have been wearing ace supports on each knee. So far these tights have been fine for runs up to 7 miles in place of the supports. Will try longer distances when I get more confidence in them

          So far so good!

            I've run several 6-12 mile runs in these since I got them, and so far am definitely satisfied. Most of my runs have been in mid/high 30 degree tempature range. They allow a good amount of insulation, while still allowing wicking during my runs.I was a bit of a skeptic on the knee support of the fabric, but I have to say, it has been a comfortable improvement.

            So so

              I have had the tights for 7 months now, I wore them this past Sunday for a 50 mile race it was cool (50ish) and rained most of the 11+ hours. Today is Tuesday and the boyz are not happy with the tights. If you get the chance take a look at the stitching in the crouch and ask yourself if your boyz would like to hang with that much extra material for a long period of time. That being said maybe I should have lubed the boyz more or something, but they did a great job with keeping me warm when I was cold.


                Although I'm a runner, I got these mainly for skiing because I strain my adductors and VMOs pretty regularly, and my PT suggested them. They inhibit proper form in the bumps if you're a serious skier so I wouldn't suggest them for that. I have run with them and they felt pretty good, but I didn't notice any huge effects. Too hot for summer running. I'll try them next season on tele-skis.

                Best Purchase Yet!

                  I am a novice runner who will be running in my first marathon later this year. I bought these to see if the really did help with leg muscles.
                  I've been using them for about a week now and I have found that they do make a difference. I have only used them on shorter runs, but my legs feel far less sore when I am finished than before I bought these. It has been in the high 30's and low 40's when I was using them and I found them to keep me at a very good temperature while I was running.
                  As far as the fit, they feel great. I am 5'10" and weigh somewhere between 145-155 lbs. I ordered the medium and have had no problems with slipping, or feeling too tight. I would recommend these for anyone who gets soreness in their upper legs after running.

                  Legs Lover the support.

                    They don't slide on like a normal pair of tights. It takes an extra minute or two. However, well worth the time spend putting them on. Legs have less forting after long runs. Size is right on IAW sizing chart. I clean my CW-X IAW manufacture care instruction and after dozens of washing, they still perform, as they were new.

                    Expert pants, the best!

                      I'm a keen runner but after a hard training session i always find I get quite sore thighs. With the CW-X pants I find they the best for supporting and alignment of muscle groups for optimum performance.

                      Former skeptic, now a believer!

                        Initially I was skeptical regarding the premise behind the CW-X product line. Eventually, I decided to purchase the Expert tights and one of the CW-X long sleeve tops.

                        I have been wearing both products during my cold weather runs and downhill skiing. They have made a believer out of me!

                        These tights look well-made to my eye, and the material feels good against my skin. They do a good job of moderating temperature underneath my outer shell. I feel as though my stamina holds up better during activity, and I feel much less wear and tear the next day.

                        So why only 4 stars? I do have a small issue with the length of these tights. I am 5'7", 175 and I wear these in men's S. Even at that size the knee cutouts tend to ride a bit low. I can control this somewhat by bunching the fabric in the thigh area.

                        I second this. I am also 5'7", and 170lb, and cannot, for the life of me, get these tights to stay put with the compression bands in the optimal locations. I love the tights, but I find myself yanking them back up my legs about every 1/2 mile (running).


                          I think that these tights out of the package were great. I ran a 6 mile loop with no issues and tons of support. Right before the run I started to have spasms in the front of my knee. I put the tights on and they stopped. The only thing that stinks is that they lose their resiliency after being washed 2x. Too expensive to buy another pair.

                          Poorly Placed Seams

                            The CW-X Expert Tights are ok. They definitely work with their function and they do support muscles well. I don't know how much joint support they provide but they definitely provide support to your quads in particular. The main complaint that I have with these is the way they are stitched. The seams on the inside are quite overdone and poorly placed. I found chafing after only a 5 mile run. I really can't imagine what they would be like for a longer run. I do wear them under my bike shorts for late season mountain biking and they work well for this need. I debated between these and the insulator and I am glad that I went with these. I tend to be warm any way particularly during aerobic workouts and these work well for temps down to the mid 20s. The Insulated might be a bit much for all but the coldest temps.


                              My CW-X Expert's just arrived today and I am completely satisfied with them. They fit perfectly and the 3-day shipping option worked out just right...I am a 5'9" distance runner and I weigh 147lbs...and the SMALL size fits exactly as a performance tight should...I was a bit hesitant ordering a small (thighs and hammies are fairly big as compared to the lower leg), but the small size contours just right and supports the knee area dead-on. There is no extra material in the crotch and did not slip down the leg after running in them...I will give you a better review after October 12th (Chicago Marathon)...I recommend these based on today's run...Oh yeah, one last thing, the color is not as I thought...but who really cares...we're guys!!!

                              Not all they're cracked up to be

                                After reading the reviews I expected something great, or at least a noticeable difference. I don't. After several marathon training runs I have the same muscle soreness afterward and also feel muscle soreness during the run at approximately the same point in time I have before. Also, I've found the fit isn't great. I'm 5-8 and 130 pounds and ordered size small. The knee diamond (support area) seems to slide down when I'm running. Far from being too tight, they're a bit too loose and seem slide down off my thighs. I can't pull them higher as the crotch bottoms out. These are not worth the price in my opinion.

                                I'm a long distance runner but am unfamiliar with compression tights. I am of a somewhat odd proportion- I am 6'1 with a waist of 28" and an inseam of 32-33". What size should I order?

                                Is this tight all black? Or is it actually...

                                Is this tight all black? Or is it actually grey with black design as in the picture? Thanks!

                                Best Answer

                                The tights will be two toned, whether we call it black or grey. The darker tone that you see is the support web that bands the knee and quadriceps for stabilization. The rest of the material you see will appear lighter than the reset, and if you want we can call it a dark grey if you would like but it was CW-X that chose to call the full package black.

                                I'm 6'5" 1/2" and 220, but I don't have...

                                I'm 6'5" 1/2" and 220, but I don't have thick thighs, nor do I care that they are long enough. Chart says I should be an XL, but I am afraid it would be too loose, not enough compression. My waist is 32" and last time I measured, thigh is about 24" at thickest. Help! What size should I get? Everyone seems to say size DOWN if you're unsure, whereas the CW-X size chart states the opposite.

                                I am 6'1" and 175 with a 30" waist. I ordered the large and they are too long. I should have ordered the medium. You should be good with the large. For me they are great but a little too long. They are still the best thing I have every worn for long runs.

                                I have been practicing hot yoga for two years and have been looking for the perfect short. Needless to say with the vigor of Bikram yoga, coupled with the heat (105 degrees) and humidity (68 percent) no short seems to hold up. I have tried swimmer's jammers and other various types of shorts with no success. Do you think these would be an option? Do you think they handled the movement, heat, and humidity? Thanks for your input.

                                Best Answer

                                Thanks for your question. I too have practiced Bikram Yoga and understand the stress the "hot room" can put on your clothing. You could give the Expert or Stabilyx tight a try for this application. If you are looking specifically for a short, opposed to a full length tight, look at the CW-X Pro Short or the Stabilyx Ventilator Short. I would probably suggest the Stabilyx Ventilator short for your purposes. I hope this is helpful for you.

                                I'm a crossfitter if you will. If your not sure what that is. Its a cross between powerlifting, gymnastics,strongman and some endurance running or rowing most times. Well these REALLY aid in my recovery process???

                                I own these. i don't feel they aid in recovery, they just aid in muscle support during workouts which may help a bit with fatigue. Does less muscle fatigue mean quicker recover? i guess so, but you will have to try for yourself. they are also very warm, so it needs to be about 48 or less to wear them outdoors during running. your best bet for faster recovery is to ingest a protein/carb blend sports during your workouts such as accelerade. i run trail races and triathlons, and protein sports drinks make massive difference in revovery for me.

                                I hike the Grand Canyon each year during Memorial weekend. I am interested in using these tights for the support they provide but am concerned about using these in 100 degree weather. Can you use these tights in hot weather and not over heat due to these tights?

                                I have a pulled hamstring and want something to wear under ski pants to minimize risk of re-injury. Also, is this appropriate to use with a compression bandage. Thanks

                                Richard, i own these pants as well as the 3/4 length and I sized mine so they fit very tight -the 3/4 are much better for ski boots. I don't think the tights themselves will aid in preventing injury, but if you wrap in addition, you might get the additional support you're looking for, and depending on how you wrap, you can probably wrap either under or over the tights. One warning, I find the tights very warm, so it would have to be pretty cold to comfortably wear these under ski pants in any temperature over about 25 degrees. Cheers, and good luck.

                                I recently bought a pair of these tights...

                                I recently bought a pair of these tights and am astounded with the results they have provided. However, the knee portion of the tights rides down, and I am thinking that I have the wrong size. Is there any truth in my hypothesizing? If so, do I need a smaller or larger size? I currently have a medium, and I weigh 158 at 5'9.

                                Thanks ahead of time! I will leave a review once I get my issues straightened out.

                                Hi There. The CW-X Support tights are designed to stretch and fit a range of height and weights. In your case, I would recommend a size Small due to the 5'9 height. I am 5'11 and 175 and I wear a Medium. Hope this helps.

                                What sort of tights would be suitable for...

                                What sort of tights would be suitable for golf to wear under trousers where the golfer is looking to get some support for sore knee joints

                                These CW-X Expert Tights have excellent knee support. That was the first thing that caught my attention on my first run. They are also insulated enough to provide a comfortable temperature in probably any condition you would dare play golf in. (my runs so far have been in 30-50 degree weather and the insulation is perfect)

                                Getting ready to go for a run with these pants and I've never known the answer to this question... what are you supposed to wear with these pants for "support"?

                                Best Answer

                                There are three things you can wear-1. regular cotton briefs, which will get clammy. 2. support boxer briefs from underarmour, nike, adidas, etc., which are expensive. 3. And don't laugh-control top pantyhose, which give an extra layer of warmth and wick sweat well. They also keep your boys from jumping around. If you feel less masculine, think about this-football players wear them to keep warm and look at all the tights available for men. Believe me I wasn't crazy about the idea until I tried it. And they are cheap.

                                I'd be awfully surprised if the tights went on sale other than during Backcountry's half-yearly sales. From an outdoor retailer's standpoint, they're really not season specific, and the product lines don't change all that often.If you're really trying to ask 'Is this thing really worth the money or should I only buy it if I can get a deal?,' I have to answer with a resounding and emphatic YES. CW-X tights are all that they claim, and more. You'll be happy, even if your wallet won't be.
