Rated 5 out of 5 by from The best light weight pant on the market I work outside every day and need to stay limber. Whether it's swinging a hammer wearing a pouch or running a chainsaw with donned chaps, my Arch Rock pants are flexible in the crotch and just stretchy enough in the knees. These pants are as tough as they are quick to dry. Even with an layer of long underwear underneath, my Arch Rock pants are flexible. The hand pockets are easy access. I like the leg zipped pocket but would make it a little smaller as anything with weight tends to ramble around in there. These pants are truly three season pants stand alone and a great water resistant winter pant with an added thermal under layer.

Rated 4 out of 5 by from Some of the only slim fit hiking pants out there Just got them so no durability test yet, but these fit my slim build more than almost all other synthetic hiking pants. I was looking for some skinny leg pants that are easy to ride a bike without having to bother with cuff securing and something that was not so strange looking that they were workplace incompatible. These pants fit the bill. Seem to be slightly larger in the waste with a 30" fitting my normal 31". Only less than perfect aspect is the nylon fabric clings a bit to the skin and makes more noise than some other types. I really like the REI Adventures pant fabric more but they have rather wide (straight fit) leg openings that get in the way of sprockets.

Rated 5 out of 5 by from Great product Wore a pair of these pants nearly 24/7 while on an 8 day backpacking trip in the Sawatch range recently and they performed more than adequately. Comfortable during long days of hiking and durable enough to withstand sliding down boulders and downed trees. They are also water resistant enough to get you through a light rain. They did fit a hair loose on me but with an elastic belt were just fine. They also work great as a pant to wear underneath waders while fishing. All in all a great product I would recommend to anyone who wants a pair of performance pants that can take abuse in the field!

Rated 5 out of 5 by from Multi-Use Pants Highly Recommended I bought a pair of these to wear on a trip to Europe, and absolutely loved them. When I returned home I immediately ordered a second pair in another color. While I am glad another reviewer finally found his slim fit pants, don't let those of you with less-than-slim-fit bodies like mine turn away from them. He simply means the pants are not baggy in the legs; quite flattering even for my build (5'10", 195 pounds). They make good travel pants, hiking pants, all-around use pants.

Rated 4 out of 5 by from Great for hiking and camping. I bought these a couple of months ago and have worn them numerous times since. Long hikes up mountains, a day rock climbing in Rumney, NH, camping, and as field pants while photographing mountain bike races. They are nice and lightweight and stretch well. My only gripe is they are tight around the legs from the knees down and can't go over the tops of my boots or shoes.

Rated 4 out of 5 by from Not what I expected but maybe better. I purchased these pants to become my backpacking/general outdoors pants. They are much thinner than I expected, but I have no complaints after 3 weekend backpacking trips. The black is a little dull, but I couldn't find black hiking pants anywhere so kudos just for stocking them. They're a very classy, functional pant and are surprisingly warm and breathing. Marmot is my first stop for all gear purchases, and I'm always impressed. Thanks guys!

Rated 5 out of 5 by from Great look and fit Sturdy construction. The tapered legs make for a great fit and make them less baggy than a lot of the other pants on the market.

Rated 5 out of 5 by from Pants that Rock I purchased the shorts and absolutely love them. When I saw the pants in the store I had to have them. I wear them everywhere from the trails to the office. Very comfortable and a must buy.

Is the a full cut pants or fitted? Is the crotch gusseted? Are legs articulated?

Asked by: Viper-10
The Arch Rock Pants will have a relaxed fit. Marmot considers a relaxed fit to be relaxed at the waist, slightly tapered at knees, with a straight cuff opening. The pants have articulated knees and a gusseted crotch for increased range of motion.

Are these pants durable enough for rock climbing? Not sure 94% nylon is durable enough.

Asked by: Love the Northwest
The Arch Rock Pants would be a fine choice for rock climbing.

Do these wants make noise when you walk? I.e. Do they make that classic synthetic material swishing sound?

Asked by: Luke L
These pants don't make noise like a waterproof material would.
