Warm Feet for Better Sleep in the Backcountry
Cold feet can make even the most comfortable sleeping bag feel inadequate. The Zpacks Down Booties provide an additional layer of insulation exactly where you need it, helping your feet stay warm throughout the night without the weight of bulky thermal footwear.
Unlike conventional sleeping socks, these insulated booties use high-loft down insulation to trap warm air around your feet. Their soft, lightweight construction makes them particularly comfortable inside a sleeping bag or quilt, where they can provide extra warmth without restricting your movement.
They are especially useful for cold sleepers, ultralight backpackers and quilt users who want to improve the warmth of their sleeping system without carrying heavier equipment.
Premium 950 Fill Power Down Insulation
Filled with premium 950 fill power Muscovy duck down, certified to the Responsible Down Standard (RDS), the Zpacks Down Booties offer an exceptional warmth-to-weight ratio.
Depending on the size, each pair contains 20–32 g of high-quality down insulation, providing excellent loft and thermal efficiency while keeping the total weight remarkably low.
The down efficiently traps warm air around your feet and compresses into a very small space when packed. This makes the booties an excellent choice for ultralight backpacking, thru-hiking, bikepacking and cold-weather camping, where every gram and every centimetre of packing space matters.
The premium down is used without added chemical down treatment, preserving its natural loft and insulating properties.
Ultralight Ventum Ripstop Nylon
Both the outer shell and inner lining are made from Zpacks' exceptionally lightweight 0.51 oz/yd² Ventum Ripstop Nylon.
This ultralight fabric helps keep the booties soft, comfortable and highly packable while protecting the delicate down insulation inside.
The material features a PFAS-free C0 durable water-repellent (DWR) finish that helps resist light moisture, rain spray and body moisture. The materials contain no added flame retardants.
Combining premium down with an extremely lightweight shell creates a highly efficient insulating layer that delivers excellent warmth without unnecessary bulk.
Fully Reversible Design
The fully reversible design allows you to turn the booties inside out and wear either colour on the outside, giving you two colour options in one ultralight accessory.
Available in contrasting colour combinations, the booties offer the same comfortable fit and insulating performance regardless of which side faces outward.
Their soft, flexible construction makes them comfortable to wear inside your sleeping bag, while the lightweight design allows them to pack down into a remarkably small space when not in use.
Whether you're relaxing in your tent or preparing for a cold night's sleep, the Zpacks Down Booties provide simple, effective insulation with virtually no weight penalty.
Perfect for Ultralight Backpacking & Cold Nights

Please note: The Zpacks Down Booties are designed primarily for sleeping and relaxing at camp. They are not intended for hiking or regular walking, as the delicate ultralight fabric is not designed to withstand abrasion from the ground or footwear. Treat them like a sleeping bag for your feet. The water-repellent finish helps resist light moisture, but the booties are not waterproof. Keep the down insulation dry for optimal warmth.
Complete your ultralight cold-weather insulation system with the Zpacks Down Jacket, Down Mittens and Zpacks Down Hood.
Care Instructions
Storage: Store loosely when not in use to preserve the natural loft of the down insulation. Avoid leaving the booties compressed for extended periods.
Washing: Hand wash only when necessary, preferably after a long season of use. Use warm water and a down-specific detergent such as Grangers Down Wash. Gently move the booties through the water and rinse thoroughly. Machine washing may damage the delicate ultralight shell material.
Drying: Gently squeeze out excess water without twisting or wringing. Allow the booties to air dry thoroughly, preferably in the sun or indoors in a well-ventilated area. Periodically separate any damp down clusters to help restore their natural loft. Avoid high heat, which may damage the delicate shell fabric.
