Bought two pair this fall for trail-runs through the Northern Arizona alpine forests. Great support and comfort. Will wear as a base layer this winter when the snow flies and the wind is knifing through normal clothing. I will agree with other reviewers that you need to up a size. I wear mediums for a perfect fit in all other pants type wear, when I got these for my first run, they felt short and during the entire 6-miles, they kept pulling down and I was constantly yanking them up ("sagging" is unbecoming and unsafe when solo-running in the backwoods). Backcountry took 'em back and exchanged them for larges with no hassle. The larges fit perfect. Backcountry has made me a loyal customer. These tights won't dissappoint.

I am a 5'9" 127Lb freshman college cross country and track runner (distance). I purchased the men's small, they fit pretty good although the "knee diamond" isn't perfect. I have used these several days for the past 3 weeks and really like them. They do a great job keeping my legs warm (tested from 24 to 42+ degrees Fahrenheit) and i believe the insulating web does work. My legs feel better and i just jumped my mileage up substantially so they helped to keep my legs from feeling the effects like normally. I also bought the "CW-X Expert Tights - Women's" (not insulated) for my 5'3", 100-110lb girfriend (another runner on my team) and she really loves them, in fact, we did mile repeats (5 of them) and when we were done she said "thank you so much for these! (pointing to the tights), they felt soo good!".

I'm a Pro Ski Instructor 5 days a week and Ski Patrol 1 day as well. On the seventh day I free ski or teach. These tights keep me warm or cool and help me keep my Legs fresh. These garments Really Work!!!!

I purchased these for a climb up Mt. Shasta in northern California. I was looking for something with a better fit and better moisture-wicking capability than regular long underwear. The CW-X Tights fit the bill. Conditions changed from freezing winds in the morning to almost balmy temperatures in the afternoon. I wore the tights underneath wind pants and cold or warm outside, my legs always felt comfortable--and dry. Whether or not the muscle and joint support helps endurance... after the 14-mile, 7,000+ ft ascent/descent, I drove home about 4 hours away. I'm not in super shape, over 50, and starting to have knee issues so, yes, I think the tights provided extra support.

Bought the men's small for my female 5'9" 125 frame and the women's small for my 5'4" 130 husband. Mine fit perfectly and stay in place. Husband's are a nip tight in the waist, but his legs fit great. We're both 55 and found the support let us ski moguls all day, whereas we use to crap out around 2 PM sans CW-X.

Went to Jo-Ann Fabrics (sewing store) and bought some low-profile cord locks (those do-dads that snug up your hood & hem) and used a tweezer to fish the CW-X drawstrings through the cord lock opening; now it is a snap to loosen/tighten the drawstring during the day. CW-X should add them to the design.

Husband is warm in the tights under ski pants. I wear thin silk long johns over mine to stay warm.

Also bought them for our son & his wife and they won't snowboard w/o them. Really makes a difference in the fatigue factor for them.

I'm 56, and consider myself in good shape. I'm passionate about skiing, and I climb 14ers and mountain bike to stay in shape during the summer. These tights came highly recommended in Skiing Magazine, and always being on the lookout for the latest technology in good gear, I had to have a pair. The tights I got don't look like the picture at all...there are no support panels, just the thin stitching lines. The tights do feel good when they're on, but I can't honestly say that they provided much additional support, and I didn't feel any less tired after a hard day of skiing. My knees felt good, but my quads were still screaming at me. I wore them twice, just to give them the benefit of the doubt, and the magazine claimed they were toasty in cold weather. It was cold the last time I was on the mountain, and I have to say that I have some Smartwool longjohns that are a lot warmer. If I had it to do over, I wouldn't invest the hundred bucks. Live and learn.

I have the regular CW-X tights and love them, but with winter needed something heavier and wind proof. These fit the bill. When I first got them I was highly skeptical they were heavy enough, because they felt close to my regular CW-X, but they truly keep me warm, although I have only been running in snow and ice in 20 degree weather. However, I feel confident they will keep me warm in colder temps.

There is one complaint. I think they ought to offer various inseam lengths. I am only 5'7 and the bands for the knees are just a little too long so I have to pull them up several times during my run. Also this time I bought a smaller size and while it is tight it works better.

Bought these tights for winter rides or runs. I'm not sold on the patented conditioning web technology as they don't really stay in place as you move, but they are nice tights if you can get them on sale. I'm 6'2", bought the XLs and they are a bit long. I position the web as stated in the instructions but end up pulling them up to belly button height to stretch out excess material so you're not going to win any fashion awards. They seem durable and weather resistant. Buy these if they're on sale, if not, get some standard tights.

Love these tights. Purchased in early Fall. Was not sure for sizing to abide by the height or waist measurement -- being they need to fit snug, the waist is more accurate. I am 6'2" and about 160. Medium is more effective than the large. I own both the 3/4 and full length. Have used mostly for cycling. 3/4 were great for fall rides. Full length are very warm. Wore cycling thru Yellowstone in late October in sub-freezing temps. Warmth was no problem and muscle support is excellent. Highly recommend and will grab more in the future, especially when on SAC.

Having just purchased the men's tights from CW-X, I have to admit that they were certainly warm on a cold Vermont weekend skiing, but to suggest that my leg muscles felt better would be a reach at best.
Not quite sure how much a compression pant would do at the start, I can't say that they made any difference at all.
And at the price being asked at any store, I don't think they are a great value. I will however use them to see if over time, I fall in love with them.

I found them a little tight but i fall between small and med. with most sizing. i got the small and they are just right, they provide Great support to the knees and lower back and they seam to wick well and are very warm.

I'm wearing the insulator pant over a pair of padded biking shorts. I ride my bike to work once a week (it's roughly 16 miles round-trip) and during the cold winter mornings (temperature slightly below freezing) they still hold up. An amazing product.

Seem to be good; good quality. Not sure how much the webbing helps, but I feel supported and warm in them.

These tights are just the best. I've do plenty of winter running and I love them.

They keep me warm and dry (from sweat).

Use them for any aerobic outdoor activity in winter weather. Your body will benefit from the support they offer the joints and muscles.

I've been using the midweight CW-X tights for over a year now. These new insulated versions are fantastic. On colder mornings I use them for my normal trail runs. I can't wait to try these as a base-layer for skiing this winter. The leg support these tights provide help my overall performance and my legs don't get as tired. Great product.

I've become a bigger and bigger fan of these tights as I continue to use them for more and more activities. I originally bought them for cold weather running, but have been using them for mountain-biking, rock-climbing, and even as a base-layer beneath expedition-weight capillene on really cold ski days. They'd really be sweet for running if they added a bit more insulation in the swimsuit area but I guess we need to preserve the market for insulated underwear. I highly recommend these tights and will likely buy more pairs downstream!

I had seen all of the ads for CW-X products over the years, and I finally gave in and got the Insulator tights. They are awesome. I wore them on a 15 miler yesterday morning and I feel fresh today! It was also 34 degrees out yesterday and I was toasty.

The pants work great in the cold.
The sizing chart might be a bit off. I am 6'0" and 200lb the chart says I am a large, but mediums fit me the best. I may even go to a small. CWX needs to have in between sizes i.e. med-large, or even long- or short-medium.

The tops of the pants could be shorter in length from the waist to crotch.

I recently purchased a pair of the CW-X Insulator Expert Tights in anticipation of a hike to the top of Mt. Marcy NY in mid February. Expecting temperatures below zero at the summit along with a difficult winter climb, I was very interested in an article of clothing that would help keep me warm and offer muscle support. Needless to say, CW-X more than came through. I stayed plenty warm and felt strong throughout the journey. I especially noticed a significant difference in my knees. Having had two major knee surgeries the CW-X helped support my knees and allowed me one of my most comfortable winter climbs ever.

Just wanted you to know I tried your CWX tights. I bought both the top and bottom to see how they worked for me. I always ski with my right knee braced by an Ace bandage to provide it with extra support after blowing out my ACL and medial miniscus several years ago. I used to race salmon, dual salmon and super G but after my accident, I just free-skied. After I used this product, my r/knee hardly ached at all and I felt more support. The upper tights gave me more circulation in my upper body, and I never felt cold at all or too warm. I would recommend this product to not only advanced skiers but for those who have circulation issues. Hopefully, if I feel this good next year, I try racing again. Oh, by the way, I am over 50 and I think this product will help me continue to ski aggressively.

Kept my legs warm througout the day. Felt great although not sure how much muscle power it gave me.

The tights fit well enough, although the drawstring is uncomfortable and don't hold them in place... you need to rely on your quads to keep them in place. They look good, but I didn't run any faster. They do block out direct wind to keep the breeze from turning my skin red and they wick moisture away fairly well. In my opinion, not worth the extra $$.

I run all winter long and winter in my neck of the woods is cold- often down to
-40C (for you non-metric people that's damn cold). My legs feel the same in these tights whether it's just below freezing or instant nose-hair freezing. Highly recommended!

I'm 5'11" 175 and medium is a good fit. Snug but not uncomfortable. So far the bottoms being in the boot have not been a problem. I teach skiing and am in gear all day long (4 days so far and no complaints). It would be more convienient to have a fly, but not a key issue. Legs feel good and old tender knees have not complained. A well made product.

I was very pleased with the Insulator Expert Tights. My lower legs, calves and hamstrings felt the extra support provided by the tights.

Excellent

OK.. maybe I thought purchasing these plus my new racing Madshus skis would win me the Cascade Crest Title...... unfortunately they don't tout it improves your VO2 Max and it didn't. But it did provide a comfortable and supportive racing tight that I am pleased with. With the nice contours and styling my legs look pretty muscular too. Beware..... wear windshield underwear too with these so you don't frostbite your member.
