3F UL GEAR TYVEK Sleeping Bags Cover Camping Bags Waterproof Ventilate Moisture-Proof Warming Every Dirty Inner Liner Bivvy Sack

Original Intention Of Design: It's frustrating to get your sleeping bag wet with condensation when you hike,People who have traveled long distances have probably experienced sleeping bags that become less warm due to moisture. I tried to solve this problem by covering the sleeping bag with a tyvek,Because tyvek is waterproof and breathable,But because tyvek is so lightweight and easy to shift, it was inspired by the bottomless sleeping bag,Full closure of the foot can better protect the foot sleeping bag, also has the function of positioning,The upper part of the open design only needs to be covered on the sleeping bag, no sense of restraint,It is waterproof while also has a certain heating effect. However, due to the waterproofing property of tyvek itself and the design structure of this product, it is not recommended to use it alone!
