Looks like a great bargain -- but I wouldn't recommend it for summer.

The single-wall design means the tent won't "breathe" well. That's not a big problem in winter, when the air tends to be dry, but in typical summer humidity, your breath will condense on the walls and roof of the tent. "Double wall" designs have a breatheable tent body and a waterproof fly. In dry, warm weather, you can leave the fly off and the condensation is able to fully escape. In rainy and/or cool weather, the condensation forms, not on the tent walls and ceiling, but on the fly, where you won't bump up against it.

The Wenzel looks like a great bargain for winter solo camping, but it'll be a steam pit in summer.

I use a tarp with a bug screen. Other people really like the hammock (and I want to try it myself).
