Part of the four-piece Modular Sleep System, the UCP Bivy Cover is an outer shell that is waterproofed with a GORE-TEX lining.   They say GORE-TEX is breathable, and technically it is but it can get sweaty if you don't manage your layers.  That said, a bivy is essential if you don't have adequate shelter otherwise.  Used condition, we consider these Grade 2.  You can use DWR wash to help reinforce the waterproofing.
