Extend your hammock sleep, even in cold weather. Designed for winter bivouacs and chilly evenings, this insulating underquilt made of 320D nylon and TC cotton fill conforms perfectly to the shape of the hammock to block drafts and retain body heat.

Thanks to its adjustable cord and carabiner ends, it fits most hammocks (single or double). Its water-repellent outer fabric protects against nighttime moisture, while the soft interior optimizes comfort. Easy to compress into its 30.5 × 16 cm waterproof carrying bag, it fits in any backpack.

Ideal for lightweight backpacking, four-season camping, or cool-weather backyard naps.
