    Comments about Three Wire Bivy Sack:

    This bivy was adequate for a summer backpacking trip. I have not encountered bad weather conditions while backpacking with it, so I do not know how it holds up in rain or snow. I chose this over the one-person tent for weight savings, but it is obviously not as comfortable. I cannot sit up in the bivy, but there is a good amount of space at the head. I feel confident that it would hold up well in rain conditions.
