One of the most usefully simple pieces of equipment you can carry quite literally anywhere, the Black Diamond
Ski Strap will come in handy in the most opportune of situations. Strapping your skis together is the obvious usage, but they also come in handy in emergency situations or when you simply need to hold something down. Create a makeshift sled to help someone out of the backcountry, or strap your pesky roof rack down if it comes loose. Carry a few of these in your pack and know you are prepared!
