My best piece of gear. Ever.
This by far has been the best pack I've owned. Period. I've used it for back country skiing, snowshoeing, alpine climbing, hiking, and even mountain biking. I purchased the pack in January of 2009 and still am using it to date. Not much wear or tear after several thousand miles and well over 500,000 vertical feet of use since the purchase. I run mine with a 6 liter MSR Dromedary hydration bladder, custom axe/trekking pole attachment system on the left shoulder strap. I've also added clips to stow the trekking/ski poles to the sides of the pack as well.
The main drawback I see with the pack is shoulder/back venting. I understand that the pack is primarily used during the winter season, though I've seen the Deuter equivalent (Freeride 30) rigged with breathable mesh. If this pack had that feature incorporated in the future I'd be the first in line for one.
As far as longevity, the nylon materials the pack is made of have withstood the elements incredibly well. Minimal signs of wear after being used for long periods several days a week. I did snap the frame about six months ago, however I was able to purchase some aluminum rod about the same diameter as the existing frame and bent/shaped the rod pretty much to the exact dimension as the original. Works like new again.
Everytime I find myself looking at packs it has been hard to find anything like this Outlaw. It's been an excellent piece of gear for the last couple years.
