a simple hammock sock made from 1.1 (30 denier) ripstop nylon, weights 15 oz. alone (stuffsack size shown with 12' 1.8 ripstop nylon hammock) it features a fronkey style drawcord channel made from 1'' grosgrain with some shockcord for stretch. for those that don't know a hammock sock is used for blocking wind, trapping a few degrees of warmth, and providing privacy. it was a few easy hours work and cost barely anything( i bought from magnafabrics.com for 66. a yard!) anyway, carry on!
