DAKINE DK Impact Spine Protector

Though your phone and that gas station sandwich you've been carrying around for so long it's no longer classifiable as a sandwich may not survive a spill, Dakine's DK Impact Spine Protector does add a layer of somatic protection to most of the brand's snow and bike backpacks. The low bulk profile doesn't restrict movement or distract from the suffering while you're working up the switchbacks on the front half of your local loop, but it does provide some impact absorption to help smooth out any user errors after you drop in on the B side.
