FOUR-SEASON MOUNTAINEERING BIVY
The Big Agnes Three Wire Bivy is a four-season, single-wall solo bivy shelter designed for the ultralight minimalist who values additional space and comfort. The external DAC NFL poles set-up quickly, providing extra room overhead as well as covered venting under the awning. The extra-long side zipper allows for easy entry/exit with a full mesh layer underneath for venting in good weather. The lightweight nylon, ripstop fabric floor provides ultra-durability and the 3-layer fabric with electrospun nanofiber technology provides high rates of waterproofing and breathability to help manage moisture and keep your interior microclimate totally comfortable.
