The Rab Ionosphere 5.5 Sleeping Mat combines cutting-edge insulation technology with thoughtful design to deliver exceptional warmth and comfort.

TILT reflective film minimises radiant heat loss, while Stratus™ R insulation traps air to prevent convection—maximising warmth without excess weight. The featherlight 20D upper fabric feels luxurious against skin, backed by a durable 30D base that withstands rough terrain. Oversized outer chambers keep you perfectly centred throughout the night, eliminating edge pressure and ensuring restful sleep in any conditions. Its spacious rectangular design accommodates all sleeping positions, ensuring comfort whether you're a side sleeper or prefer to sprawl.

The innovative low-profile two-way valve paired with a convenient pump sack makes inflation and deflation effortless—no more wrestling with your gear at camp. Everything you need travels together: the compact roll-away stuff sack keeps your mat organised, while the included repair kit means you're prepared for any mishaps on the trail.

 Lightweight, practical, and built to last, this mat transforms your outdoor nights into genuinely restful experiences.
