Cycoactive Forest Hemp. I know, it makes me sound like a dirty hippie, but I just thought it was neat. Not the coolest pack, but it works well for me. Hauls all my tools and water-what more do ya need? Had to replace the reservoir a while back so I got an actual Camelbak one from the LBS. Lovin' it!
Got a GoBe, too, but it's a little small, plus I have to wear it awfully tight to keep it from hangin' on the seat or low branches. It's better for short rides.
