The Baffin Bivy is an ultralight, 17oz, and super compressible bivy. The Baffin is a minimalist bivy for alpinists, big-wall climbers, or for use as an emergency back-up. Using Drizone™ fabric that is highly waterproof and breathable yet light weight, the Baffin Bivy will be your go-to bivy when every ounce counts.
Sierra Designs’ 100% nylon Drizone™ waterproof/breathable fabric does a suburb job of sealing out wind, rain, and snow while venting internal moisture, helping you stay dry, comfortable and protected in any type of weather. Sierra Designs selects 2-layer, 2.5-layer, and 3-layer Drizone™ fabrics for different equipment pieces to provide the best blend of weather protection and moisture management for any activity.
