Sean L.wrote a review of Voile Ski Straps 9 Through 24 inches on January 16, 2013
Familiarity: I've used it several times
Extremely rugged straps. I use about 6 on my pack for various "quick-access" items (Shovel - AVI probe). A couple of the 24" straps hold my MSR snowshoes to the bottom of my pack.
They're pretty tough so far. They look as though they aren't secure as they are but don't let that fool you.
Bottom line = Expensive and worth it.
