Mountain Equipment Helium 600 Women's - Down Sleeping Bag 3-Season

Mietprodukt

Warmth meets lightness – down sleeping bag for women with alpine demands

Are you planning trekking tours, mountaineering trips, or fastpacking adventures where every gram counts – but you don't want to compromise on sleeping comfort? Then this lightweight 3-season down sleeping bag is just what you need. Designed for women who travel during the transitional seasons and in high-altitude terrain, it combines high-performance insulation with thoughtful design and sustainable materials.

Tailored to your needs – women's specific cut and EXL® system

This sleeping bag is specifically designed for the female anatomy. The close-fitting Alpine Fit reduces the amount of air inside that you have to heat up with your body heat – so you stay warm faster and longer. The elastic EXL® seams keep the down filling close to your body without restricting you. This ensures high efficiency and an exceptionally comfortable sleeping experience – whether in a bivouac or a tent at 2,500 meters altitude.

Efficiently insulated – no room for cold air.

To keep you warm even in sub-zero temperatures, this down sleeping bag features angled box baffles that effectively prevent cold spots. The Gemini™ insulation baffle along the zipper keeps drafts out, while the robust thermal collar with Lode Lock™ closure traps your body heat. The ergonomically designed footbox ensures warm feet even in lower temperatures – a detail you'll quickly come to appreciate.

Recycled materials, well-thought-out function

Both the outer material, Helium 20D, and the inner lining, Supersoft 20D, are made from recycled fibers – robust, breathable, and pleasantly soft against the skin. Weighing less than one kilogram and with a small pack size, the sleeping bag fits easily into any trekking backpack. The included stuff sack is waterproof and reliably protects your gear from moisture – ideal for multi-day tours with unpredictable weather.

Temperature ranges according to the manufacturer

✅ T-Comf: -5 °C (Eddy's temperature recommendation for this model is approximately -1 to -4 °C for comfortable sleep)
✅ Temperature limit: -11 °C (limit for experienced sleepers)
✅ T-Extreme: -31 °C (emergency area, not suitable as a comfort zone)

The "Good Night's Sleep" rating for this Mountain Equipment sleeping bag is a manufacturer's recommendation – based on practical tests and experience – and complements the official EN 13537/ISO 23537 standard (T-Comf, T-Limit, T-Extreme).

What does this information mean exactly?
"Good Night's Sleep Temperature" = Temperature at which you can sleep comfortably without feeling cold – even with prolonged use or under real-world conditions such as:
✅ lightweight sleepwear
✅ thin sleeping mat
✅ possibly damp weather
✅ Fatigue or hypothermia due to daily stages

Note on temperature perception
The temperature ratings are provided by the manufacturer and are standardized. In practice, however, they can vary – especially if you are exhausted, hungry, or wet. The quality of your sleeping mat also has a significant impact, as down compresses at the back and therefore provides less insulation. A good sleeping mat is therefore essential for a warm night.
