I sell these primarily for lashing crampons onto a pack and ski's. 

Voile Straps. Made of tough stretch polyurethane and a hardened aluminum buckle. Voile Straps have many uses. You should always carry a few Voile Straps when traveling in the backcountry. A-frame skis on your pack, fix a pesky climbing skin, hold your shovel and probe together and of course hold your skis together for transport.

I sell the 15 & 20 inches straps by the pair. the 20" is perfect for crampons.
