Boa Constrictor Skin (it's big and can swallow anything and the shock cords squeeze it all down....) Larger than a snake skin, I wanted to make a pair of sleeves large enough that I could 1) quickly stow my hammock, air mattress, air pillow....2)allow this gear to air out or dry out hanging off my backpack. 3. be lightweight.
After it slipped over my hammock, with the air mattress inside with plenty of room to spare, I realize it could be a bit narrower.
(Let me know of any changes to the pdf I should make. And if there are good examples to follow. I'll upload some photos of the Boa Constrictor Skin after my next camping trip. )
