Kayu™ Women's Down Mummy Sleeping Bag
Overview
When ultralight adventures require peak performance, Kayu is the answer. An ultralight down mummy bag, Kayu features careful tailoring of the hood and footbox, plus a body-mapped core that creates an optimal fit with no excess weight or wasted space. Premium 800 FP down and aggressive, thermally efficient patterning make it a trusted companion on longer journeys where every ounce matters.
Our flagship Thermo Gill™ vents allow you to regulate temperature without letting in drafts, deeply extending the useable temperature range and improving overall comfort. Further increasing your comfort is a suite of top-shelf fabrics, including 20D nylon ripstop with DWR on the shell, an ultra-smooth 30D nylon taffeta lining, and a 40D nylon ripstop waterproof/breathable footbox.
