It’s frustrating to get your sleeping bag wet with condensation when you hikePeople who have traveled long distances have probably experienced sleeping bags that become less warm due to moisture.

However due to the waterproofing property of tyvek itself and the design structure of this product it is not recommended to use it alone!
