Not sure why Tim doesn't get more love here. I can only think it has to do with the zippered foot box in a hammock thing. Mine is no issue and I see this as myth.
My 40F ProdigyX long wide has seen loads of action and rocks it hard. In the rain with no tarp even. Love that Apex and EEs work is top notch. Big thumbs up for EE. Prices are very hard to beat.
I've not tried his KARO baffled down under quilts but it won't be long now. The RevX 20F TQ is in my immediate future.
