I use these pants primarily for lounging around base camp and hunting. While I was hesitant to spend so much money on pants, I figured I just need one pair that will keep me warm in the freezing mornings when I'm stationary in my spot that can also compress down into my pack for when I'm hiking around. Secondarily, I needed a comfortable pair of pants for lounging around camp after putting in miles all day. These are darn near perfect. Too many pants have bulky adjustment straps, zippers, or plastic loops around the waist that dig into your hips when you're wearing a pack with a waistband. These pants are very minimalist and designed so well. I am 6'1" and 195lbs with a 32" waist and the medium fits perfect. The stretchy crotch and reinforced lowers are nice features. The only negative, as others point out, is these pants will not hold up to crawling through sage brush or crawling on your hands and knees for very long. But, if that's what you're doing then you'd be sweating in these pants anyway. The OR gators can be thrown on over these to offer even better protection if your worried about snagging them.
