The Black Diamond Ski Strap has always been a tried-and-true classic; effectively holding together any pair of skis. This stretchy strap now has a facelift, and is still likely the most versatile piece of gear—use it to strap a camera tripod to the outside of your pack, or lash skis and poles together for a makeshift backcountry emergency sled. Snag a few and stash them in your ski packs and in your car.
