For those cooler nights
A lightweight, versatile bag with plenty of room for comfort on cooler nights. The KSB 35 features a 650 fill power down top and synthetic fill bottom provides exceptional warmth-to-weight ratio. Right at home in the backcountry or the backyard, this bag features Length Locks™ that can shorten the bag, and a two-way zipper that allows you to open the foot box for ventilation. Unzip the bag all the way to convert it into a generous blanket.
