Rated 5 out of 5 by from FINALLY the perfect long underwear bottoms After years of wearing fairly uncomfortable bottoms, I thought I was just the wrong shape. Until these babies. SO COMFORTABLE! I'm about 5'1", 110 lbs and the S fit is perfect. The length is just right and the bottoms of the leg openings don't have a thick seam that digs into my ankle when put into a ski/snowboard boot. The wide waist band is amazingly comfortable and doesn't ride too high. I wore these under my waterproof pants for 2 weeks camping in Iceland and barely ever noticed they were there except that I was warm and cozy. I highly recommend these as a baselayer for hiking, running, skiing, snowboarding, or just around town! It doesn't hurt that the Coral Flynn Glitch color is really fun too.

Rated 5 out of 5 by from Brilliant! Length is perfect for me (5'2"), the design is very fun. Material is soft and even though midweight it is not bulky. Will work so well for casual wear in the cold city, every day! The rise is not super low and not super high, just right. The seams are all in the right places. I really like the wide waist band. I LOVE these. Highly recommend.

Rated 5 out of 5 by from The best!! These are the best long underwear I've ever owned. Granted I've only used them once so I can't speak to their durability, but I wore them as a baselayer for a frigid January climb of Mt. Washington. Unlike other brands I've owned, these bottoms stayed up! No yanking them up all the time. They are surprisingly thin and I worried they might not be warm enough, but I was toasty with a thin soft shell trouser over them and water/wind proofs (above tree line). They wicked like a dream. I love that there's no seam at the bottom, so they don't rub my ankles. They did seem a wee bit short (I'm 5'6") but that wasn't a problem with the socks I had on and will be an advantage with ski boots. I love these so much that I just ordered two more pairs!
