Weighing 440g with an R-value of 5.5 and packing down to a compact size (19 × 9 cm), it offers a well-balanced option for those seeking dependable warmth within a minimal setup.\u003cbr\u003e\u003cbr\u003e\u003cspan class=\"Y2IQFc\" lang=\"ja\"\u003e\u003cspan\u003e\u003c\/span\u003e\u003c\/span\u003eAt Wanderout, we selected the Wide version to reduce cold air from the sides while allowing more room for stable, comfortable sleep. Compared to the regular 51cm width, the Wide measures 64cm across, helping prevent your sleeping bag from slipping off the mat and ensuring greater stability. Its insulation performance is suitable not only for spring and autumn but also extends into colder seasons.\u003cbr\u003e\u003cbr\u003eThe newly developed tapered mummy shape pursues a balance between ultra-light weight and high performance. By offsetting the perforations between horizontally aligned chambers, internal air convection is reduced, enhancing thermal efficiency. The 8cm thickness distributes body pressure effectively and provides a stable sleeping surface.\u003cbr\u003e\u003cbr\u003eInside, Rab’s TILT (Thermo Ionic Lining Technology) incorporates two layers of metallic-based reflective film that reflect radiant body heat, significantly reducing heat loss. This allows the mat to achieve high thermal performance without adding unnecessary structural weight. The soft-touch fabric helps prevent your sleeping bag from slipping. A low-profile two-way valve enables easy inflation and deflation, while the included pump sack allows for quick setup. The side-opening stuff sack ensures smooth packing and unpacking.\u003c\/p\u003e\n\u003cp class=\"p1\"\u003eDue to its tapered shape, the foot area is slightly narrower.
