I have an older model undercover as part of the super shelter system for the Hennessy Hammock. This does not include the foam pad or the over cover, it's the undercover only. This was originally used on the ULBP, however, I purchased from a HF member and I used it on my Explorer Deluxe and it worked fine. There is a tear on one end (see picture). I primarily use a WBBB-DL right now and the pad works well on that setup so I cannot part with that.
I will sell for $10, shipping included, just to cover the fees and shipping.
