Our Verdict

If you have tried bivvying and decided it’s not for you, or you have wanted to try a bivvy but feel you may be too claustrophobic, the Three Wire Hooped Bivvy from Big Agnes may be worth some consideration. It’s roomie inside, we used a NeoAir Topo Luxe mat inside (the largest mat we had on hand), and the three hooped bivvy swallowed it. There was plenty of room inside for you and a large sleeping bag if needed.

It’s a straightforward pitch, just one pole. The bivvy can be secured with five peg-out points, though only three pegs are provided, unless in strong winds, once your matt is inside, that will give the bivvy most of its structure.

 I’m assuming the “three wire” in the Three wire hooped bivvy refers to the three additional guy out points (you only get three pegs, and eight are required if you wish to peg it out fully), two at the feet and one at the head. These increase the internal volume, pulling the bivvy taught, but If you want to get the most volume out of this feature, incorporating a trekking pole to help lift the guy live vertically, then pegging out the bivvy would add even more space.
