With a focus on comfort, the BACKCOUNTRY BIVY LONG from Sierra Designs is a minimalist sleeping bag that lets you sleep happily on the canvas.
At 218 cm long, this full-size model has enough interior space to be compatible with the revolutionary Backcountry Bed bag and the Backcountry Bivy airbag. It features a waterproof membrane and abrasion-resistant floor, stitched together for extra protection in inclement weather, and covered with a durable PFC-free water-repellent coating (DWR) for extra protection.
This sleeping bag has a large opening and a mesh vent that offers an unobstructed view of the shiny canvases.
