For sale here is a 2QZQ Underquilt Protector. Breathable Ripstop Nylon in Coyote Brown. For Gathered-End hammocks (I used it on an 11' Warbonnet Blackbird XLC and it fit fine).

The purpose of this thing is to:
- protect your underquilt from splashes from the ground, and
- provide some protection from cold wind (which otherwise would be more likely to blow between your hammock and your underquilt), and
- when used in conjunction with an overcover, simulate a hammock sock in retaining some heat that otherwise would leave your sleep system.

While this is a very elegant solution that definitely accomplishes all of the above, I prefer using a full hammock sock.

This has been used exactly once. No issues that am aware of. $33 shipped CONUS.
