So recently i bought a XX large regular Grid Fleece ls top with antimicrobial treatment (Weatherproof brand) at BJ's for 10 bucks. I was able to make a great, very breathable active backpacking vest out of it (weighs a little over 4 oz), a pair of mitts, 2 hats, and 2 partial balaclavas all out of this one shirt. It was super easy and super fast. The great thing about this material is that it doesn't really need to be hemmed and won't unravel, so except for the mitts there wasn't any sewing involved.
First photo is me with the vest, mitts, hat, and balaclava on:

Back of vest showing where i cut out the material to make the mitts and increase breathability for when wearing a backpack:

Last picture shows the 2 balaclavas and 2 hats together, all cut from the sleeves–the ones in the middle are the balaclavas and the ones at the top/bottom are the hats:

So, 10 bucks for 6 separate pieces of gear, not to shabby.
