Mountain Equipment Firefly Regular

The Mountain Equipment Firefly sleeping bag is an ultra-light and particularly breathable model, ideal for summer use in the mountains and 3 seasons at lower altitudes!

ULTRALIGHT AND BREATHABLE
The sleeping bag is made from a Plasma™ 10D membrane, an ultralight and particularly breathable membrane which limits the risk of condensation. Thus, it weighs only 560 g while ensuring a comfort temperature of 2°C.

THERMAL EFFICIENCY
Its partition construction limits down migration, offering uniform thermal efficiency while minimizing weight and bulk. The sarcophagus cut provides excellent thermal efficiency and limits heat loss. It adapts to the shape of the sleeper's body while ensuring great freedom of movement. Featuring Russian goose down filling, the Firefly sleeping bag is also equipped with a collar which provides warm comfort. The Firefly sleeping bag will be an asset in any high alpine environment in late spring and summer.
