Damn, I came here hoping to be the first person to say REI. I picked up an Osprey 2.5L hydration pack just last week and it's a beauty for hiking use. I could spend hours in REI poking through all the nifty gear and gadgets they've got. I really should've picked up a pocket sleeping back- 8 feet in length of insulated protection against the night packed into a nifty 3-inch cube. The REI I hit up had a portable kayak on display, and for as little faith I put in its integrity, the little ark looked pretty neat.
After REI?
I dunno, maybe American Eagle. They've got neat clothing.
