Nemo's impressively refined closed-cell foam sleeping pad, the Switchback Ultralight packs comfort and insulation into a small and lightweight pack size. The thermal film layer efficiently reflects heat back onto your body. Suitable for use as a standalone pad or in addition to another, providing an extra layer of comfort. Why not add this sleeping mat to your ultralight camping kit!Features: Highly-efficient, hexagonal nesting pattern allocates more space for taller, wider nodes, providing significantly greater plushness. More precise tooling eliminates wasted space between folded layers, enabling taller nodes to nest tighter for a smaller packed size. Taller nodes create more space for uncompressed sleeping bag insulation, trapping more warmth around your body. Premium dual-density Axiotomic foam offers a supple layer for comfort and a resilient layer for support. Metallized thermal reflective film reflects heat back to your body and is protected by a durable film. Axiotomic dual-density foam is optimized for well-balanced compression and abrasion resistance. Extremely easy to use and delivers comfort and security for all types of adventure, from mountaineering and thru-hiking to camping on a budget. Folding panel design allows for lightning-fast, easy setup and packing.
