Heated USB Down-Cotton Sleeping Bag

Description

This heated USB down-cotton sleeping bag is built for cold-weather adventurers who refuse to compromise on comfort. It combines down-cotton insulation with built-in heating elements powered via USB or Type-C, so you stay warm when temperatures plunge. The outer shell is waterproof and treated to resist wind and light rain, helping protect the insulation and heating components. With 3 adjustable heat settings—low, medium, high—you can optimize warmth and power usage depending on conditions. Lightweight design and compact packaging make it ideal for backpacking, travel, or emergency preparedness. The envelope or mummy shape (depending on model) zips up snugly, blocking drafts, but some bags also unzip into pads. With a power bank (5V/2A recommended) you can get many hours of heat even in freezing temps. The interior is soft and skin-friendly, avoiding irritation over long use. Dual zippers and reinforced stitching add durability. Perfect for winter camping, hiking into high altitudes, or just staying warm on cold nights under the stars.
