Inspired by the demands of navigating hostile environments with minimal kit, the Ionosphere 5.5 makes no compromises on warmth for weight.
Engineered with precision to deliver exceptional warmth in a compact size, this insulated air mat is ideal for alpinists and adventurers exploring in winter conditions.

Low on weight, high on comfort, it thrives on long-distance ski tours, winter fastpacking trips, and multi-day ascents.
