Got a pair of these in 2007 and don't wear anything else backpacking or hiking except shorts when it's warm. The seem very durable but I do have a couple picked seams on them (but nothing indicating that they're about to fall apart). The fit is "athletic," which is actually quite nice when you're in the middle of an athletic endeavor such as backpacking. I really like the strechiness of the fabric, which makes make up for any feelings that the athletic cut may be binding on movement. Plus, they're quite water-resistant as well. What more do you need?

Awesome pants. Extremely comfortable, fairly lightweight, and very stretchy. They are adequately breathable for not having vents and the mobility you are afforded is unparalleled. Two downsides: there are no rear pockets and the sizes, at least to me, run small. I'm normally a large waist but the tall large version seemed too snug around my legs - had to get the XL version. Regardless, the parts are so comfortable that the positives far outweigh the negatives.

I have just returned from a 10 day backpack stone sheep archery hunt (successful!) in northern B.C. and wore the Gamma LT pants the whole time. They are the best backpacking pants I have ever used. Very light, completely non-binding, wind proof and nicely water resistant. I never got wet despite VERY wet weather (I did use rain gear for sustained rain but didn't need it for mist and light snow). The cuff drawstrings made gaiters unnecessary. Highly recommended.

Nice material, pants are designed great. I like how stretchy they are and block wind well. Except for the stitching that is coming out. Arc'teryx should think twice about doing business with China. They are a good company and are starting to sell out for less quality. Arc'teryx has alway's been high quality, just all the Arc'teryx clothing I have that was made in China is crap and will be returning.

The title says it all. If I'm not wearing shorts I wear these... every day. There is simply not a better pair of pants out there for cycling, walking, golfing, going out... Comfortable, nicely fitted, stretchy... Great pants.
