WS adjustable tension.
I added a Dynaglide WS to adjust the total length of the shock cord suspension from the design length to a several extra inches. Found at max length the Yetis still seal tight, but allow for easier repositioning(sliding up and down the shock cord) and it more or less stays put where I position it. Eventually plan to replace this WS with a much longer one. The original intention was to have a venting system that could easily be adjusted from within the hammock without having to slide the Yeti up and down along the shock cord suspension.
