Mountain Equipment Helium GT 400 Sleeping Bag Long anvil grey

Designed for the long-haul and especially comfortable for those who like to sleep on their side as well as on their back, the Helium GT series provides greater comfort and more ‘wiggle-room’ without sacrificing performance thanks to their significantly more generous yet tapered fit. Made with PFC-Free and 100% recycled fabrics and built with the same featureset as Mountain Equipment's standard Helium range, these bags remain highly compressible and reliably warm for extended road trips through the seasons.

A light, versatile and highly packable bag with a little more space for added comfort. The ideal choice for backpacking and travelling through summer and cooler spring nights.

Helium 20
Weighing only 38 g/m², helium 20 uses 20-denier-yarns to create a fabric that is compressible, robust and extremely comfortable. Its densely woven construction ensures maximum down density, wind resistance and heat loss resistance. The new Helium 20 offers a better hand feel than previous helium fabrics and reduced seam slippage, resulting in even longer durability than the previous fabric.

Down 700
The high-quality duck down has an actual minimum down cluster content of 90 %, has a fillpower of 700 cuin and is Down Codex approved.

Down Codex
Mountain Equipment's Down Codex controls and reduces the risks within a down supply chain in order to meet the high animal welfare standards and the high quality standards. The goal was also to present the complexity of a down supply chain in a comprehensible and above all transparent way.
