Product detailed description
The three-season down sleeping bag brings the latest innovation in the form of patented WarmZip™ technology for daily adventurers.
The spacious rectangular shape when you want it, or the mummy shape when you need it, lightweight and packable Boost 650™ offers the choice of comfort in nature.
- WarmZip™ Technology
The patented central zipper design allows the bag’s internal space to reduce into a mummy shape, increasing insulation around the sleeper and raising warmth by up to 6°C. Unzipping the zipper converts it back into a spacious rectangular shape for added comfort.
- Choice of space and warmth
Enjoy the freedom of the spacious rectangular bag shape or cozy warmth in the mummy bag shape – simply zip it up to choose the shape and temperature that suits you for a comfortable night’s sleep.
- Multi-purpose hand openings
Read a book, play cards, or simply unzip the bag – all without leaving the comfort of your sleeping bag. The hand openings provide an additional ventilation option during warm nights under the stars.
- Zone down insulation
Plenty of impregnated duck down with a fill power of 650 and a hydrophobic treatment, certified by RDS, is divided into key areas using zone insulation to maximize heat retention and minimize total weight.
- Eco-friendly product
The top layer and lining are made from 100% recycled nylon with GRS certification, which is soft to the touch and coated with a water-repellent layer free of PFAS.
- Wide selection of sizes
Each size – Small, Regular, Long – is also available in a wider version thanks to the zipper opening, so you can get the sleeping bag exactly as you want and in the size you need.
- Additional features
