I bought a couple just to have. Not sure what I'll do, yet. I may harvest the down, maybe make some sleeves like the JRB set, but for starters I'll just pull the sleeves inside out, zip it up, and put it inside my Pancho Liner UQ for a little extra warmth. Probably all I'll need here in TX, and I'll also have a down jacket to use as a layer as well (even if it is orange!).
NOTE: Online reviews at JCP.com note that material is not very substantial and may not be suitable as outer layer due to risk of tearing or punctures. Those who have already purchased...thoughts?
