A truly unique device developed to connect your tarp to a tree with thin 1.75 mm hollow braid line. Dutch Flyz are the smallest, strongest, and fastest way to tie off to a tree without actually tying and untying a knot, even when wearing mittens. Designed for the most weight conscious hiker. They can be moved easily to any part of your ridgeline and quickly locked into position. Their unique design will hold in the windiest condition and never need a backup knot.
