Part of the four-piece Modular Sleep System, the ACU Bivvy 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 bivvy is essential if you don't have adequate shelter otherwise.
Used condition, you can use DWR wash to help reinforce the waterproofing.
