For summer use I have a poncho tarp 1,4x2,4 m in diagonal pitch and get almost the same side coverage. Definetly not the best for winter use.
Would prefer to use a minimal of 1,2 or 1,5 m of side coverage (per side) and at least 3 or 3,4 m long. Splash and blowing rain in high winds can be dangerous at reasonable temps (5-8° C).
Anyways it's a nice and cheap summer tarp.
I only have a tenth wonder UL hammock with whoopie slings but none of their tarps.
