REI Minimalist Bivy Long
I picked up this bivy used from another backpacker at a steep discount just to try out a bivy type setup. The REI Minimalist Bivy is 88″ in length with a shoulder girth of 64″. Mine weighs in at 16.2oz despite the listed weight of 17oz. It is a 4 season bivy with serious rain protection around its 6 zippers that can be used to “wear” it in camp. It does have a mesh window that needs to be covered for true all weather protection.
I am really glad I went with the long personally because I’m a bit claustrophobic and the extra space makes this type of setup reasonable for me. Also I like that it is a 4 season bivy because up until this, I had not had a 4 season shelter and I really like having that option in my gear closet. Overall it is exactly what is advertized, a good solid 4 season bivy. It’s not ultralight, though it does meet my 1.5lb or less criteria. It’s not for serious mountaineering, but it gets the job done!
