How is it possible to sleep comfortably in summer, when you camp one night in a warm valley, and then move to a high altitude cold bivouac the day after? How can you convert a part of your sleeping system into a survival tool for serious winter conditions? Answer: use a comforter!

The L500 completes our "Ultralight Modular Line" series, that I created in partnership with Cumulus. The modular comforters we developed have been adopted by hundreds of enthusiast ultralight hikers.

Weighing only 750 g, made of a 27g/m² Pertex Quantum shell and including 500 g of our best 850 cuin goose down, the L500 is a kind of Swiss army knife in terms of insulation for users up to 195 cm. It’s down filling ratio is optimized for the quilt mode. It has a wide amplitude of use, from 25°C to -6°C.

Integrated elastics allow to create a footbox on one side and a neck collar on the other, loops being used to create a tube. The result is a quilt, a hoodless sleeping bag, not insulated in the back. With this L500, when it gets cold, it is useful to shake the quilt in a U position before sleeping, in order to put more down on the top. Comfort use in quilt mode is around 0°C. Of course you can reach even lower temperatures, depending on the clothes you wear while asleep.

Rectangular shape is a deliberate choice: it creates, in case of an emergency , an armour-like insulation layer (torso, arms and head) when used under a wide jacket. In static use, this "jacket mode" allows you to deal with a -12°C standby. The perfect backup for quick but careful climbers.

It is also possible to use it inside of a classic sleeping bag to make it winterproof, and under a hammock... and of course , as a comforter at home : expect serious heating savings!
