How feasible would it be to make an insulated poncho liner? I stumbled onto a site called thru-hiker http://thru-hiker.com/materials/insulation.php Could I take the Climashield and the Momentum 55 they sell and make a decent one? Would it be worth the effort? I know it won't be as good as the Kifaru, but since money is tight I figured I'd ask. Wanna kill these ads? We can help!
