Freestyle BivyPack is not just your regular backpack because this one turns into full-size tent or sleeping bag for a single person to sleep in. The BivyPack when in backpack form functions as waterproof bag and when opened the same waterproof part of bag keeps legs and feet cozy. 300 denier polyester diamond weave ripstop, SilNylon for roof and SilPoly is used to construct floor. The whole material is thin thus making it lightweight carry. The shoulder to head length of tent is noseeum bug netting to protect you while sleeping. The head-side tent is kept higher using two carbon fiber poles so you easily move your around. Pledge a Freestyle BivyPack for $200 at kickstarter.
