Crafted with precision, each sleeping bag from Mountain Equipment boasts a unique foot piece section tailored to its specific use. In the case of the Helium range, the Trapezium 4 foot piece is designed for maximum lightness and compressibility. This innovative four-part baffle system stands as their lightest and most technical solution, prioritizing the lowest possible weight.

Recognizing the significance of heat loss through the head, Mountain Equipment has engineered a hood with five baffles, creating a truly anatomical shape to envelop your head in luxurious warmth. The Gemini System takes insulation optimization further, featuring two overlapping anti-snag draft tubes and a fully integrated neck collar.

The Helium 600 is a sleeping bag that excels in versatility, packability, and, most crucially, exceptional warmth. Well-suited for cold-weather pursuits in early spring or late autumn at altitude, or winter use during lower altitudes, it embodies a perfect blend of innovation and functionality for a comfortable night’s sleep in challenging conditions.
