Go solo. Go ultralight. Go anywhere.

The Big Agnes Three Wire Bivy is built for fast-moving adventurers who refuse to compromise comfort for weight. This four-season, single-wall bivy delivers extra room and reliable protection for ultralight missions where every gram matters. The external DAC NFL pole system creates generous overhead space and covered venting, while the extra-long side zipper makes it easy to get in and out—even with layers or a sleeping bag.

Designed with advanced electrospun nanofiber technology, the three-layer waterproof and breathable fabric balances protection and moisture management, keeping your microclimate dry and comfortable in any condition. With durable materials, reinforced stake-out loops, and a simple setup, this bivy is ready for alpine ascents, fastpacking trips, or any solo night under the stars.
