Just got back from a trail run on this cold fall day and I must say that I'm in love with these tights. The combination of warm soft material plus the snug support makes it feel like you are being hugged by a soft cuddly bear while your running. They are wonderful!!!

Ever since buying the regular stabilyx tight, I've been praying for an insulated version for those really cold days. Now I have it! These are awesome and the windpanel in the front covers all the right spots. Definitely worth the money!

I was excited to try these out on the first sub-freezing day of the fall. Too bad, though, because even at 30 degrees, my legs were cold.

Beyond that, I'd say the stabilizer stuff made my legs want to snap back to straight, which sort of shortened my stride. I'm not a fan.

Ow, ow, ow. According to the size chart, the Small should fit me, but these were painfully tight & really dug in at the waist. They also seemed short from the knees on up, but if I got 'em pulled up enough so they're not droopy drawers, then they were painful in the crotch, because of the seam that goes from front-center, down through the crotch area, and up to back-center -- and the seam is thick and NOT flatlock. Big design flaw in such expensive tights. With the seam like that, there was no point in my trying the Medium. I sent 'em back. The concept behind the tights seems good, but the execution of it is not. (Not when I tried them a year or two ago, anyway.)

Looked sweet. Put them on - supportive panels felt badass. Thought they were going to be a box of warm goodness, but I just ran in them for a evening run in 28-30 degrees and my thighs and tush were cold! The supportive panels are insulated, but the remainder of the material is not. I have some Pearl Izumi tights that are warmer...maybe I'll just have to wear a layer over these...

I am a big fan of the Stabilyx Tight line. It's not because I am weak or old. It's the technology of the tight that make you endure for a longer and more strenuous training. The tight allows each leg muscle groups to have better circulation and with the insulation sensors, it keeps me running in very cold and difficult weather. I wish there is a top that have similar technology to keep me warm. In addition, it does vaporize the sweat from inside out. I especially love the knee wrap design, which stabilize the knee joints. The most unbelievable thing is that, some mornings I work out without it, then I put it on for evening training. The soreness from the morning workout goes away faster with the tight on. Try it & you will know what I am talking about.

I've owned two pairs of the basic CW-X Tights for at least 3 years and have enjoyed them tremendously (they're still in great condition - well made and durable). After suffering through a long walk on a cold, windy morning recently, I decided to give the Stabilyx Insulator tights a try. I found the tights to be warm, even in the wind. The Stabilyx version is more supportive than the basic CW-X tight, and if you're on the upper end of the size chart, you might need to size up unless you have a very slender build. I'd definitely encourage you to contact customer service if you have any concerns about the sizing, especially if you haven't worn super-supportive garments previously. I have a small waist with curvy hips, and am long-waisted with an average inseam length. I have to cinch in the waist (there is a drawstring), but must be careful not to let them pull too tight through the crotch (major ouch - and one of the other reviewers noted an issue with this area, as well). If you're using these tights on a brutally cold day in the wind, you might need to add wind pants for extra protection. I could also see wearing these tights around the house to help with leg fatigue.

I like these running pants quite a lot. They perfect for running in a cold weather. I got size M which fits me well, 5'9" and 130lbs. Very helpful customer care support (I had a ? about th size, got the answer right away and change the size I had previously ordered). I'm hoping they last long...

These insulator Stabilyx tights (IST) are wonderful. I have the non-insulated expert tights as well, which is very nice also, but I think I actually prefer the fit of the IST. I am 5'9" and 145 lbs, and i wear small in CW-X. Expert tights fit well, but I wished it was a (tiny) bit more snug. IST has a much more snug fit, hence it feels more supportive. In addition to being a little more snug, IST feels a little shorter than non-insulated Expert tights. I can make up for it with longer socks.

I went for an 8 mile run this morning at about 37 degrees though a hilly course and my legs definitely felt supported. In case there are many of you, like me, did not really understand how compression tights actually help your legs, let me tell you what my dad who is a MD told me. He said that when you get older, and when you run, a lot of the blood is collected in your legs, in the blood vessels (veins specifically), trapping with it things like lactic acid, Co2, etc that should return to the heart to be recycled. This is primarily caused by gravity. By strategically compressing certain parts of the legs, you are in effect reversing the downward gravitational pull of the blood, so that it does not gather stagnant in your legs. Apparently there are compression sleeves and socks for older folks who suffer from varicose veins, so the concept is not new.

Needless to say, after my 73 year old dad tried the IST, he is asking one for his birthday. He says he may just wear it around the house to keep his ankles from swelling.

these tights are fantastic, can't imagine running without them. Love the support!!

when I first put them on I felt like a stuffed sausage (and I am not fat) and immediately wanted them off. Tried on again the next day- wore them around the house and kinda started diggin the compression love. Wore them snowboarding- they are great! Warm base layer and compression kept the spring in my lower legs. I will definitely get another pair.

I got this for my wife and she loves it! It keeps her warm on the coldest days. She has used it on relatively mild days also with no complaints about over heating. Great product.

I love CW-X tights. I have the Pro Tights and the Insulated Stabilyx. They do definitely help prevent/delay fatigue on long runs. The insulated version are a bit warmer, but not much, which makes them great as you don't get to warm. I think it is the wind component that they are best for. Definitely, love CW-x products. I have the shorts also but it has been to cold to try them out. I believe the difference between the Pro and the Expert is that the Pro has back and abd support panels.

They almost got five stars from me, they are neat looking, and overall very comfortable and warm. I just came back from a 1.5 mile (I'm a beginner!!) run in 32 degree farenheit in Manitoba, and I wore the tights alone, and was comfortable in that temp (they'll be fine for me for the sunny warm winter days I'm sure) My complaint is the Large that I bought based on my weight, is too long for my height (5'6). Now I only have a 30" inseam, so it's not uncommon for me. I'm only hoping that soon enough I can move to a smaller size, which hopefully will be closer to my height. At that point I want to try some of the uninsulated, as these are very good!

These were my first CW-X tights, and now that's all I want! They feel great.
