The 3F UL Gear Tyvek sleeping bag cover is not a bivvy bag, it is not designed for use on its own outdoors. So what is it for?
The best explanation is that it would be extremely useful for those that prefer to or want to use a down sleeping bag in damp or wet conditions. Or are concerned about condensation in their tent.
Tyvek is a breathable and highly water resistant (it sheds water) that is also tear resistant and abrasion resistant. It is also incredibly lightweight. It will also add extra warmth to your sleep system.
We offer two versions, clearly demonstrated in the pictures. Both are mummy shaped.
Both pack up very small.
