I had to return these because they didn't fit me right. After reading other reviews, I wanted to like them. But the size small indicated for me (what I usually wear too) felt baggy in the crotch area. Even when running, they didn't feel right, and I was always wanting to try t hike them up or adjust them. Fit through the legs felt fine, and they seemed to be working as expected, but the rest of the fit was just not right for me.

Just back from 10 days of skiing in Utah with the cw-x pro and insulated tights. My 75 year old knees never have felt this good after a ski trip. The insulated expert tights are truly warm and seemed as supportive as the pro tights. Two ladies at my yoga group had recommended them to me and I'll never be without them... (the tights as well as the ladies). Congratulations on a great product.

I use the CW-X 3/4 insulatedd expert tights for skiing, so I figured I'd pick up a pair of these pro tights for trail running this fall and biking.
One thing, order a size smaller then what you wear! I'm a medium, but use a small in the CW-X. My girlfriend had to do the same thing, as she's usually a small, but is an x-small in CW-X.

I love these running tights though I use them when I workout. The support is better than anything else I've tried and the compression is bang-on. The only thing I could wish for is a pouch front as this would make them a bit more comfortable. Never the less, these are great.

CW-X really got it right. Can ski/run/bike/hike with far less energy drain. Legs feel great at the end of the day. Perfect for warmer weather skiing, skiing on the glacier in the summer, and dry land training in the fall. Pick the CW-X insulated tights for colder weather; they work just as well in more extreme conditions.
Order them one size smaller than you usually wear.

I'm an avid cyclist and I've just returned to running after a eight year lapse. These are the best tights ever! First of all, they stay in place and don't droop down like saggy draws. Somehow my muscles feel refreshed after I run and with stretching I'm never sore. Great product. I highly recommend them. I'm 5'10" and a medium fits me well both in length and rise.

I purchased the Pro Tights for skiing. I'm 6'1", 180 lbs, and a very agressive off piste skier. Now in my mid-30's, the pangs of a hard day have become more noticeable in the lower back and knees. The Pro Tights are very well made and tailored, and fit like a glove. However, the claims of less muscle fatigue weren't immediately noticed. I did feel good afterward, but I guess there is no quick substitute for pre-season conditioning. I give the termal properties an average grade at best, but I don't know if the manufacturer claims this to be a major attribute. I wore them under North Face Patrol pants with XCR Gore-Tex on a breezy high 30's day on Mammoth Mountain. Bottom line, great fitting pants, but maybe not worth the case. I think I may get similar or possibly better performance from a termal half the cost.

I really like my CWX tights. I bought them to wear in a cold weather marathon about a month ago, and have worn them a few times since. I can't say they helped me run any faster than running without tights, but I probably ran faster than if I were wearing conventional tights. My only gripe is that CWX has fairly precise sizing recommendations that I didn't know when I bought my pair, and as a consequence, bought a large when I should have bought a medium. I didn't have time before my race to return them. So, the tights are fine, but I'm not sure that I get the benefit of their design.

Love the tights! Excellent support for hamstrings and knees. Do a great job wicking away sweat and definitely decrease recovery time. I'll be getting another pair!

I just got these last week, and I must say- I feel a huge benefit when I use these on my trail runs. I wear the tights underneath my sweats since they are a little flashy, but they are not hot at all. On the contrary, they keep my skin a lot drier and cooler. I have a bad lower back and pelvis that typically aches after excise. With the added compression and support to my lower back and hips, I don't get as tired and ache as much when I'm done.
I will use these for all my activities, even in the winter when I go skiing. I bet these will really help.

Great product. I wore them on my last long training run for the Marathon two weeks ago (24 miles) and they were great. Perfect for the fall marathon season when the mornings are cool. If the weather is not too hot I'll wear them in the Marine Corp Marathon next week.

The CWX Pro tights are great except for the tag they put right on top of your bottom! I have been ordering tights CWX since they first came out and it is like haveing a PT tape you before you go out on your practice/race runs. Next time CWX R & D dept. please think about screen printing the tag.(no you can not cut it out...the tag that is)
Your Best Friend Ever, Itchy

These tights certainly do provide support for your knees, both in terms of the anatomical webbing that provides muscle support and because they are pretty tight giving overall support to the legs. I have two pairs and do all my runs in them, whatever the weather.

These Pro Tights are great! Have been running with them for about four months now, my times have dropped, and my knees don’t hurt like they used to. It feels like you have springs in your legs. These are also the most comfortable pair of tights that I have ever worn. CW-X is well worth the extra price!!!

We used the tights for skiing. They were warm and comfortable. It's hard to tell if they increased performance a great deal or not. I think we need more time to decide. They are definitely well-made.

Pros: I have weak knees, and these are the great replacement for knee braces for skiing, biking and weight lifting.

Cons: Expensive and they look like a super hero costume!

Let me begin by stating that I'm not a tights kinda guy. I use them only out of utility such as keeping warm. These tights, however, are different. They provide support for the large muscle groups in the legs and actually make me feel less fatigued after a long run. They are perfect weight for runs in the 40-30F and should also be great for x-country skiing. Although pricey, I think the quality is great and they should last a long time. Highly recommended.

I haven't been in extreme cold with them yet but have snowshoed four times, and they are very supportive. Being a new mommy I need all the support I can get!

Very Nice Tights.
Spent 3 days at 8hrs a day chasing a 14 year old boy who loves the glades in Whistler/Blackcomb. By the way I am 190 lb 5ft 9in relatively fit 51 year old Guy.
I picked up the large size with the advice of the Gear expert and never felt better. The tights are of very good quality and are like having little springs attached to the critical moving parts on your legs and back.
Give these a go if you would like to put bounce back in your step.

It’s a great product that worked for me. I wore them on my weekly 30M trail run
(Altitude gain 4000 feet). One minor thing that I found, I felt a little strain on my lower back (much more than when I wore normal tights).

I'm 5'7" and weigh 150 lbs and the small fits well.
These tights are spendy indeed, but I have a real tough time with my legs getting tight in the damp cool air of the PNW regardless of activity when the temps dip below the mid 40's and CW-X really seems to help. Much more than "regular" running tights I've used in the past.
I have been using these as running tights so far and had hoped to use them in place of silk weight capilene for skiing this winter. They may not be warm enough for that. If it is below 50 degrees out and especially if it is windy, I wear my Sporthill 3SP pants over the tights and have had no overheating issues at all. Based on my experiences so far, I would not hesitate to get a pair of insulator tights for the cooler weather.
They really seem to shine in the recovery period after I run. I feel great. Tired but fresh all at the same time.
I haven't had any chaffing issues with mine.
If you feel like dropping the cash, I think they're a good investment. Recommended.

These are only the second pair of running tights I've ever owned, so I may not have much to compare to, but the second I put these on and ran, I felt great. Great support of the lower back for a pair of tights. Held up well in the rain, kept my legs dry and warm. Overall, I felt like my legs were able to give me a little extra effort and strength for the long runs. The hype is well deserved!

I like the feel of the support around my knees/calves/hamstrings. I don't like the way they feel around my hips, but it may be that I am just not used to it. Experiment with these before you try them in a marathon.

These tights provide good support for the muscles and tendons; 5 miles goes down like 1 or 2. wonderful

Compressed tights delay muscle fatigue and allow runners to expend less effort to reach their usual performance level. The tights have strategically placed bands of fabric that limit excess muscle motion and facilitates blood circulation. During the course of a marathon that could be equal to shaving 6 mins off your time.

These tights are great. They provide all types of support and are very comfortable. I hope that there longevity is just as good. What about different color combinations??

Great tight for long distance running. I have worn it for +20km training.

I recently competed in my first 50 ultramarathon. A cold snap moved in a few days before the race so I ordered these pants. I have also in the past had trouble with my knees at mile 18-20. So I bought these pants for double duty, warmth and muscle and joint support. Let's just say they work very well in both areas. I cannot say my legs didn't hurt after running 50 miles (yup, i finished), but they did hurt much less than when i have run regular marathons in shorts. These pants support muscles and joints to minimize movement on impact. The pants are a little spendy, but are they worth it? Absolutely yes!

Overall 4 star rating. Would maybe suggest going one size larger than expected. I'm only 5'9", and it seems that I am having to pull up on the waistband of the L size more than I would prefer. Otherwise, they feel great on the legs and lower back...and man, they look cool. Nothing like wearing half a superhero costume to make you want to run farther and faster!

I have tried sizes medium, small and large in Cw-X tights. The mediums fit well but wanted to pull down in the crotch. I thought they might be too big, so I ordered small. those stayed in place but made my feet turn blue from lack of circulation because they were so tight. I finally settled on size large, which are long enough and fit well overall. It turns out I just needed longer ones.

Unbelievable tights. Compression holds and supports great on cold evenings. So good I bought two of them!

I bought these for skiing after reading lots of reviews and lots of less-than-scientific marketing literature.

Putting these on felt like it took about 10% of my weight off my knees. That made a big difference after a day on unforgiving icy crud snow.

If you are going skiing with these, consider the insulated version. I think the uninsulated are meant for running, since they are very effective at transferring heat away from your body. Not always a good thing when you are sitting on a lift with frigid winds tearing across the mountain.

You may have to burn the waist tie ends. Mine frayed after a single washing. I have not had the "riding down" problem that some people have mentioned. They could have put a fly in, though.

Bottom line, I hated paying for them, but I'm glad I have them.

CW-X is the best running gear I've ever used. Since getting my first pair in 2002, I wouldn't run without it. Running the 400M at age 67 requires injury free training, CW-X does that for me.

These are great tights. They definitely give me support in the knee area. They provide a little resistance that takes a little getting used to, but something I forgot about after a 1/2 mile. I can't say if they improved recovery, but they certainly didn't make it worse. You can feel the difference in insulation between these tights versus the Insulator ones (I own the Stabilyx Insulator tights as well, which keep you a good bit warmer). I would recommend these tights.

Best running tights I have ever owned. High quality. Good support. A bit expensive, but well worth the money. Bought another pair to have as a backup.

These CW-X tights are awesome! I've been running for many years. Never have I come across a product that performs so well. At the end of my run I had more energy and less fatigue. The only issue I have with them is they are a bit expensive.

I was right on the top end of a small and the beginning of a
Medium. I have gone with the small and they are great. I use them
Mostly for after a race. They provide faster recovery and subdue
Alot of the soreness days after the race. They are just a bit
Tighter then the medium. Mike

When the folks at CWX said they performed years of detailed anatomical research to provide a superior product.....well, let's just say that for a pair of "exercise tights" that seemed a little extreme.

Somewhat skeptical and not a "spandex kind-a-guy", I still wanted to give these a try, so I ordered the CWX-Pro model to coordinate with some of my hiking shorts and trail running shoes. I will definitely say that after four hiking outings of 12-14 miles each, including healthy vertical gains the San Gabriel and White Mountains in CA and the Sangre de Cristo Range in NM, these tights really work wonders to keep you feeling like you have done less than half that amount of work!

I can now go to work on Monday mornings after a strenuous weekend of hiking and climbing and actually walk normally in through the front door, something that I caught a lot of flack over in the past two years! I have ordered two additional pairs of the standard CWX pattern based on my level of personal improvement with the first pair, and will most likely order the shorts models for next summer.

Thanks, CWX, for developing a truly superior product!

They are great tights - they do everything they say and more. Comfortable, supportive, etc. I have no complaints, other than the price (I have 2 pair and each time I cringed when I saw my credit card bill).

Rather than that no complaints -
