nice, but don't sleep in them.

  • Familiarity: I've used it once or twice and have initial impressions
  • Fit: True to size
  • Size Bought: small
  • Height: 5'4"
  • Weight: 115lbs

I wore these for mountain biking and hiking/scrambling around the desert for a chilly weekend, and they were awesome! I definitely appreciated the support. However I slept in them one night and that was a poor choice, I was pretty uncomfortable by morning (but I'm told this is a rookie mistake for compressive clothes). The one thing I didn't love was that they would twist and it was hard to get them to twist back to how they should be.

I think I might be converted

I decided to try these on a whim. So far I've used them snowboarding and climbing. The support is nice and I like how thick they are! Obviously they are tight. I made the mistake of wearing them a little too long after climbing and they got uncomfortable, so definitely don't lounge in them, but when active I thought they were great! I think they could have been warmer for snowboarding, but in the sun I was fine. The extra support on my quads was just what I needed. I'd say it fits tighter than a glove but that is the point. If it's too loose then it's not doing its job. They kind of feel like a thinner wet suit if you've ever worn one of those, so like a second skin. I sometimes tape my tendons when running so I look forward to trying these out to see if I can forgo the tape!

snug, snug!

These were given as a gift, but I have some feed back. The tights we a little tough to get on and adjust, but worked perfectly as an under-layer for hiking pants in cold weather. They put a nice spring in your step with the extra support!

I never understood the rage and then I tried these on. Yea, they're not the most fun thing to get into, but it's also not a problem and trust me, it's well worth it once they're on! Even though they can be a little snug to pull up over the heal, I recommend sizing on the smaller side otherwise the fabric bunches behind the knees. The pressure these provide feels great and they're insulated enough that they're great for winter trail runs and cross country skiing in. Or as a base layer on cold ski days.

Tight squeeze

  • Fit: True to size
  • Size Bought: Small
  • Height: 5'4"
  • Weight: 125lbs

Yes these pants are tight but that's what I tell myself when I roll them on. I wear these xc skiing and winter running and they are amazing. They spring my leg forward when running and when xc skiing I can just wear these and gaiters and that's all I need. They do feel like you are being cut in half when you sit down but they are high waisted so they sit at the actual waist line not hip line. The discreet black is more flattering as well as normal looking which I prefer over the other tacky splashy designs from this brand.

Tight squeeze

Squeezy pants I'm not dying to take off.

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

I was admittedly skeptical of the whole compression garment thing. Even tighter tights? Hasn't the whole skinny jeans movement swaddled my behind with enough gusto? Apparently not. I'll be adding a few more hours of squeeze into the schedule to accommodate this recent purchase.

I bought the CW-X Insulator Performx tight partly out of curiosity about compression garments, but primarily to keep warm on winter trail runs in the North East (temps 20s and 30s). These tights do warm well, no issues staying toasty, even on mellow runs. I've never been a huge fan of CW-X color patterns, so I was pleased I could give this all-black pair a whirl without offending the local deer population or compromising my fashion sense. As far as size, I measured myself and went with their recommendation, which was just right. Lastly, while I can't speak to the science of compression garments, I will say I consistently want to keep these tights on after my runs, they make my quads feel a touch less tired and noticeably more relaxed post-workout. I'll be buying a 3/4 length pair of CW-X tights when the weather gets warm, and am already plotting how to sell my husband on why he too should adopt the skinny pant movement.

I'm Sold!

    I'm totally sold on CWX tights! They definitely help with my knee pain and intermittent hip flexor irritations. I purchased several different styles and like them all. My size wasn't even on the charts (5'9" 130, athletic legs), so I ordered both a small and med and ended up keeping the medium for length since the compression was similar in both sizes. I wore these under some fleece pants the other day in 7 degree weather (on the bike trail for 2 hours) and I was nice and toasty. I wouldn't wear these alone if it was too cold or if there's much wind, but they are more substantial than the non-insulated variations.
