Rated 5 out of 5 by from Best in Class! Excellent pants. I wear them under my Gore Tex shell and they provide the perfect amount of insulation. Everyone should own a pair!

Rated 3 out of 5 by from Warm 3 out of 5 stars Great pant for keeping warm but it needs belt loops for a belt or draw string lock. The pants seem to slide down at times. I use suspenders to keep them up.

Rated 5 out of 5 by from Excellent Pants The first time I tried them on I felt like I was wearing a very good quality down jacket on my legs, much like the down jacket I bought via MH. I am heading to the White Mts. very soon so I am looking forward to using them in difficult conditions...I have all the faith. Please attach belt loops !!!!

Rated 4 out of 5 by from Very warm but ... These pants are certainly very warm...I've used them down to about 10F for ice climbing belays. Fit-wise the waist is spot-on, but I find the Med a bit long for my 32 inseam. I would like to see improvements in weight, features, and function: The weight/bulk could be reduced by minimizing the big elastic waistband. Use a partial elastic waist (say 1/3, in back# and a large adjustable Velcro overlap on each hip...done. Marmot has done this for years. I would lose the fly. It's easier to just push down the waist than to fish yourself out of the fly with gloves on. I would lose the front pockets. Who wears these in town and needs hand pockets? For other items you will surely have a jacket with pockets on. Lastly, fully separating side-zips make things needlessly complicated, particularly when the wind is blowing and/or you're standing on a steep slope. I much prefer 3/4 zips like Arcteryx has on some of their pants/bibs. You can pass your boot through #even with crampons on) and pull them up... without having to sort out which flaps mate up, and fiddling to join zipper ends, and can do so with gloves on.

Rated 5 out of 5 by from I don't know how I lived without this product Best pair of insulated pants ever. Was recommended to buy them from a few friends and I am now sold. I like winter camping and this was the only piece I was missing to make it more comfortable.

Rated 5 out of 5 by from AWESOME You can't go wrong with these pants! Super warm, love the full length zippers and reinforced rear and knees. The only knock I could give them is I would like to see belt loops....

Rated 5 out of 5 by from Must have This is my 3rd pair of compressor pants. They are a must have for long cold days out in the mountains.

Rated 5 out of 5 by from I was warm and dry while everyone else was chilled These pants are a must for extended ski tours when cold/wet/humid/marine winter climates are involved. Just got back from an extened ski tour in AK. Weather ranged from 10F-25F at night with snow cave building, block wall contruction, wind, and plenty of tent condensation/frost. I used these pants every night when we stopped. The design is perfect to step into with your ski boots still on. I always just threw these on over my shell bibs and never had a problem with them being wet, even when building snow caves. Perfect with the B'layman jacket.

Rated 5 out of 5 by from Awesome pants I am a woman 5'5" 120# and purchased the men's size small. I was afraid they would be huge on me but they fit fine. They were a little long, but with the Velcro cuffs I was able to cuff them at the base of my boots so I was able to adjust the length. I wore 2 pairs of long johns and a pair of thermal long johns underneath and I was toasty warm in sub zero temps without being active. I tend to be the first one cold, but not the case here. I was thrilled with these pants! But come on Mountain Hardwear - how about some gear for us chicks!!

Rated 5 out of 5 by from Very warm and comfortable. I love these pants. I have used them with a stretch type base layer, then a pair of Mountain Hardwear Stretch Tight Thermal bottoms. The Compressor Pants went on top used as a shell. These babies worked great. They are very warm and function great. I used them in the Artic at night. Temps at -15. The adjustable ankle cuff is nice to keep the snow and the wind from blowing up the legs. Side zips make it easy to slip the pants on and off over boots as well as great to unzip a little to regulate body temps. The reinforced knees and bottom allow you to kneel and sit on the ice without fear of ripping the pants. They are light and compress very well. The only suggestion that I would offer is to get a pair of suspenders to clip on the waist. The elastic in the waist band along with the draw string is not enough to hold the pants up if you are active. It would be perfect if it had suspender mounting points added in.
