Tell me I'm not the only person who initially read "MucusBag" as that company's name!
While the idea is novel (and manages to make an adult look like an infant, to boot), I'd worry about my legs and arms getting cold away from my body. I'm hoping to get an alpine-rated quilt setup with this hammock eventually. I do like the concept of mummybag closeness, without mummybag "mumminess". I was quite clostrauphobic in those things for the longest time.
For my UQ/TQ I should just buy one of those, slit it down the side, and hang the back half off the outside of the hammock, and lay the front half inside. Leave the sleeves whole to slide the arms into. Ooh, and it comes in black, too . A grown-up onesie...Germans
