Great light weight bivvy
Works great as a part of my sleep system, can use it by itself in the warmer months and can use it in conjunction with my sleeping bag in the colder months.
One thing I think could be improved with this product would be to have a full length zipper as it would make it easier to get in and out of, and you could then open it up and use it as a blanket.
I guess the zip is small to keep the over weight to a minimum.
