OR Advanced Bivy
I recently went on a multi-day kayaking trip in oaxaca, mexico. for most of us, this was our first time needing bivy sacks and most of us bought different models. this bivy was the most comfortable of all on the trip. because you can leave it open with the bug mesh protecting you (even in the rain), condensation was minimal -- not existant most nights. everyone else reported having their sleeping bags wet by the end of the trip - but not I! the only problem i had was that the bug mesh ripped slightly from heavy zipper use.
