I’ve got one, I really like it. Comfortable and stable, lots of organised storage including stash pocket for things you don’t want contaminating the rest of the pack contents, excellent reservoir with magnetic valve holder that really works, handy hip-pockets, good build quality. The tool roll pocket is sat right in the firing line for mud from the rear wheel, which isn’t that clever, but overall I think it’s a really good riding pack.
I had one of the original Raptors as well and the new version has sorted most of the niggles from that like the sometimes leaking reservoir, no zips on the hip-belt pockets, slightly stiffer bottom end which could rub uncomfortably.
