When hiking, it can be frustrating to have your sleeping bag get wet with condensation from tent. Long distance hikers have probably experienced sleeping bags becoming uncomfortably warm due to moisture.
I was inspired by quilted sleeping bags and bivy, so I covered my sleeping bag with Tyvek fabric. It is lightweight, waterproof and breathable. The feet are fully enclosed to better protect the feet of the sleeping bag . The upper part is open design and only needs to be covered on the sleeping bag. I found that it promotes insulation in your sleeping system.
However, the Tyevk has limited waterproofing and it is not recommended to use it without a shelter. For winter camping, you can leave the mesh at home. Bring the Tyvek bivy and you will find that the tent becomes larger.
