Das zeichnet den Fusion Zero aus
The Fusion Zero balances a low-temperature rating with a lightweight build at just 1.00 kg, making it a practical choice for hikers and campers who need dependable warmth without bulk. The mummy silhouette minimises dead air space, so the bag heats up faster and retains warmth longer than rectangular alternatives of comparable weight.
Ideal für...
Adults who camp, hike, or travel in spring and autumn conditions where overnight temperatures dip below 5°C. It suits backpackers prioritising weight savings and tent campers who need a compact, easy-to-store sleeping solution.
