Dakine Mission 25L Photo Pack
From the Editors of Snowboard:
One of the best features with the Mission is the removable padded camera block, which essentially is a fully functioning handheld camera bag giving you the freedom to fill the pack with other items that lead to a misspent youth. The vertical board carrying straps, back panel entry and tripod carrying system will keep you just a few steps away from getting the shot.
The removable block in the Mission makes it a good choice for people that want a functioning backpack as well as camera pack. Downsides include non-waterproofed zippers and no space for a laptop.
