Mummy Down Sleeping Bag - JR Gear Helium 350 Down
JR Gear Helium 350 Down – Technical Sleeping Bag, 800g, made from 20D Nylon with Duck Down Filling, YKK Zipper & Sleeping Pad Attachment System
The high-performance down sleeping bag JR Gear Helium 350 Down is the ultimate choice for mountaineers, hikers, and minimalist camping enthusiasts (lightweight backpacking) seeking maximum warmth with the lowest possible weight and bulk. Designed in an anatomical mummy shape (mummy shape), this sleeping bag hugs the body, eliminating empty internal air spaces and ensuring outstanding thermal efficiency in low temperatures, with a Comfort rating of 7°C, Limit at 2°C, and Extreme at -12°C.
The core of the JR Gear Helium 350 consists of 350 grams of premium quality White Duck Down. Natural down offers the highest warmth-to-weight ratio compared to any synthetic material, making the sleeping bag ultra-light, with a total weight of only 800 grams, while also allowing it to compress into an extremely compact size inside its carry sack. The outer shell is made from ultra-light yet durable 20D Nylon Double Cire fabric, which prevents down leakage, repels surface moisture, and provides a soft, silky feel against the skin.
Practicality and safety in the field are enhanced with premium technical features. The sleeping bag is equipped with premium Japanese YKK double-sided zippers, featuring an internal anti-snag protective cover to prevent fabric jamming, along with a large opening that allows perfect ventilation if temperatures rise. At the top, the adjustable hood with drawcord closure seals around the face to retain head warmth. Its most innovative feature, however, is the special bottom attachment system for connecting to a sleeping pad, which "locks" the sleeping bag onto your sleeping mat, preventing you from sliding off during sleep on sloped terrain.

Tactical Corner-Maintenance & Advice
The JR Gear Helium 350 Down offers a huge advantage with its sleeping pad attachment system. Down, when compressed under the weight of our body on the back, loses almost all of its insulating ability. By connecting the sleeping bag directly to a good insulated sleeping pad (with a high R-Value), you allow the pad to handle insulation from the frozen ground, while the down on the upper side remains fully lofted and keeps you perfectly warm.Storage Tip:Never store your down sleeping bag compressed inside the small carry sack for long periods at home. This damages the structure of the feathers and reduces performance. Store it loosely spread out or inside a large breathable fabric storage bag (mesh bag) in a dry place so the down can breathe.
