I'm 5'11", 155lbs, 32 waist and the Medium fit great, if not slightly big and baggy. Bought the OR suspenders from OR.com cuz I like to use those when skiing, and they would sag a bit without them. I don't use these pants as rain pants when hiking/backpacking because they are too bulky and warm, but they work great as snow pants. You would think that paclite would be too thin for a ski pant, but they are actually quite bombproof and hold up great to falls and scrapes on ice, ski poles, etc. They feel much thicker and abrasion proof than my marmot paclite jacket. I really like the full-zips on the side, easy on and off and can use them as vents. The cinch cord on the bottom is great for wearing with snow boots, and the zip-out gaiters are great (but they are mesh, so when skiing in powder, some snow does get it, but not enough to matter). I haven't worn them enough to speak about the wear and tear on the seat from getting on and off the chairlift, but they seem sturdy enough to hold up to it and its goretex pro on that part as well. Overall great product, love OR and backcountry

I have used these on 3 trips now and so far I love them, although they are for colder climates. I would like something a little more versatile. Too hot for warm climates.

Awesome pants, used them skiing, ice-climbing, hiking. Light-weight, well reinforced against crampons and ski-edges, full-length zips on the legs, powder skirts in the ankles. Never been cold in them, never got wet, and never felt restricted. If you're playing in deep powder bib / salopette type pants might suit you better or have a long jacket over the top.

I'm 5'10" and about 160 lbs. and bought these in a medium, and I have to say they fit fairly well for a hard shell designed to go over multiple layers. However, if you decide to wear only a light base layer underneath them, pick up a pair of the suspenders while you're here. The built-in belt only tightens to a point, and Outdoor Research, for whatever reason, manufactures their garments too big for the respective size. They need to reconfigure their sizing chart.

I used these pants on 2 expeditions before denali with decent success. During my Denali expedition the goretex liner started to peal off to the point where there many areas that were not protected. Pretty scary starting an expedition. The pants fit great and I really dig OR stuff but I do not recommend these pants.

With Gore breathability and waterproofness, this pant is packable yet durable enough for full on mountaineering conditions. I use them when space is an issue but need a rugged pant for unexpected conditions. They accompany me on backcountry ski days as well as adventure touring on my motorcycle. The fit is excellent for my "thicker" thighs & physique.

I have skied and mountaineered here in Alaska the last two years with these pants when I need a hardshell. They work great, durable, comfortable and keep me dry... Great Pant, jacket is awesome too!!

I'm on my second season with these bad boys and I love 'em. As a ski patroller and back-country enthusiast, they've kept me dry in the most wicked of conditions. The fit allows maximum mobility and the side zips work great for ventilation while climbing. They're also very lightweight and packable for spring ascents.

Make sure you get the suspenders though. The waist belt isn't very effective.

These pants are comfortable and look great, but the durability is poor. I've ripped them twice and the second time is clearly a design flaw. They ripped 10 inches down the right leg from the zipper seam when I leaped across a creek. The stitching is a single thin row and the fabric just ripped away.

Come on these aren't pajamas, they need to withstand a little seam stress! Maybe the OR designers are expecting you to only wear them posing in a Seattle coffee shop.

I was so excited by these pants. They fit perfectly and looked awesome. They performed great and then after 5 days of skiing a 10 inch rip opened on the inner leg. Atrocius craftmanship.
