As many of you know weight is a huge issue when backpacking. The more you have to lug around the more calories you urn and the more food you have to take in to compensate. This can cause problems when food is scarce. For this reason I decided to try a new approach to sleeping. Instead of lugging around a tent I decided to try this :
Tru-Spec H2O Bivy bag. This bag is meant to cover a mummy style sleeping bag and keep the user dry. Its waterproof, tear resistant, and extremely light. It also claims to raise the temperature of your bag by 10 degrees, although this seems pretty unlikely.
First night I spent with this thing was...problematic. This was mostly my fault as I didn't have a camp mat to sleep on and the temperature was way to cold. But one thing I noticed about the bag on every camp out was that it is difficult to breath with the head flap over you. It isnt THAT noticeable, but its enough to speed up your breathing. This is a problem for sleeping...
I've also noticed that the material is thick enough to stay up on its own, and with enough clearance between your face and the bag the breathing problem isnt an issue. Still, I plan to try and make something to hold the fabric off my face at night, we'll see how that goes.
The material is extremely strong with no tears yet. It also repels water beautifully, but I haven't had a chance to try it in strong rain. Overall I like it, but if the breathing problem continues to be an issue I may switch over to a one man tent.
