I want to replace my hexagonal hammock tarp with something intended for ground sleeping. (I'll use it with a bivy bag.)

Basically, I want something I can pitch high and airy to provide shade during mid-day siestas, or low to the ground on the off chance of a storm.

Something like an MLD Grace Tarp or GG SpinnTwinn would be optimal. If it has a bug net option for the Sierra, that'd be cool too, but not necessary.

Whatever I buy, it needs to ship via USPS Priority Mail this week (I leave for the PCT on the 11th).

Whatcha got, BPL?
