I've rocked everything from spyder godfathers to helly hansen pants and the sessions gridlock. These are hands down my favorite. The removable liner is super comfortable and awesome for cold days, and it gives the pants a lot of versatility for warmer days when you dont need the liner. They seemed super tough and took a beating until I blew a seem when ate it off a cornice, accidentally doin a bit of the splits while I had them sagged a bit. I dont blame the pants for this, and Backcountry was cool enough to take care of me, making a crappy situation, not so crappy. At the end of the day, you really feel like you've got on a great quality pair of pants that are worth the money, and then some.
