Great pack with all the right features. . . zippers are shot after about a year and a half of sweating and cinching em back and forth. Still works, just compromised, don't want a bike yard sale after a wreck, lot harder to pick up all your mtb bits than your pole and planks! Armor carrying I've usually strapped the leg pads underneath, FF as shown, and the elbows are either worn or stashed inside the FF helmet. The sunglass pocket fits just that, not goggles. Nalgene make a superior reservoir in my opinion, and if you get the wide mouth you can throw a beer or two in the bladder for when you reach the top. Just wash the can first.
Only downfall is storage. . .If I have an extra downhill tube, you can kiss carrying anything in the main compartment goodbye, especially if the bladder (3L) is full. Plenty of stash pockets for tools, etc. Killer pack, but when she dies I think I'm gettin' the new Amp. . .
5 stars would be the zippers still working and slightly more room.
