This is my version of a winter sock. It has a panel of Nanoseeum at the head that you can turn to a varying degree to vent or even totally enclose you. It is made from ARGON 90 and Nanoseeum so it is breathable but has a quality DWR for quilt protection. I have 11 foot and 10 foot versions. It is designed to work with a hammock with a ridgeline. Tapered on one end and drawstring on the other. The Winter Sock has a panel of nanoseeum above your head and can be turned to vary the amount of venting. This comes with a mesh stuff sack. Comes in black and of course it is made in the USA.
