Underkilt - Thermal protection for hammocks

Thermal insulation designed for the hammock

Unlike a traditional sleeping bag, the underquilt is positioned under the hammock, avoiding any heat loss caused by compression of the filling. The result: even, constant, and enveloping warmth, ideal for cool nights in the great outdoors.

Made from durable 40D jacquard nylon, it is filled with 250 g of spun cotton, offering an excellent balance of insulation, breathability, and comfort. Its soft, machine-washable lining allows for regular use with ease.

Ideal thermal comfort range: between 5°C and 15°C, perfect for spring, autumn, and cool summer nights.

The combined use of a Topquilt and an Underquilt provides protection against subzero temperatures thanks to double thermal insulation.

1. The hammock sleeping area is actually suspended in an arc, and an overly wide insulating pad tends to shift or wrinkle when turning over, which reduces its thermal efficiency. The current size is the optimal size designed for most standard hammocks, providing full coverage of the back and shoulders while avoiding excess material that could be unnecessary.
2. Thanks to its more compact size and insulating padding, this product stores more easily, making it ideal for backpacking or long trips by reducing load.

We have added drawcords to the four corners of the underquilt, and we have also designed a central adjustment system so that the sleeping bag adheres better to the bottom of the hammock, thus offering better thermal insulation.
