The three-season down sleeping bag brings cutting-edge innovation in the form of patented WarmZip™ technology for those who love everyday adventure.

A roomy rectangular shape when you want it or a mummy shape when you need it, the lightweight and packable Boost 650™ gives you the choice of comfort in the great outdoors.

  • WarmZip™ technology

The patented center zipper design allows the interior of the bag to be reduced to a mummy shape, increasing insulation around the sleeper and increasing warmth by up to 6C. Conversely, by unzipping the zipper, you can obtain a spacious rectangular shape for greater comfort.

  • Choosing space and warmth

Enjoy the freedom of choice in the spacious shape of a rectangular sleeping bag or the cozy warmth of a mummy-shaped sleeping bag - choose the shape and temperature that suits you to feel comfortable at night, just zip it up.

  • Multi-purpose hand holes

Read a book, play cards, or simply zip up your jacket – you can do all of this without leaving the comfort of your sleeping bag. The arm holes offer additional ventilation for the sleeping bag during warm nights under the stars.

  • Zone dust isolation

Ample 650-fill RDS-certified, hydrophobically treated, impregnated duck down is distributed to key areas using zonal insulation to maximize heat retention and minimize overall weight.

  • Environmentally friendly product

The shell and lining are made from 100% GRS-certified recycled nylon, which is soft to the touch and coated with a PFAS-free water-repellent coating.

  • Large selection of sizes

Each size - Small, Regular, Long - is also available in a wider version thanks to the zipper opening, so you get the sleeping bag exactly how you want it and in exactly the size you need.

  • Other advantages

YKK anti-snag zippers, adjustable hood, zip puller, roll-up collar and two-way entry zipper. Comes with compression and storage bag.
