The SIM Ultra 3.8 is a lightweight self-inflating sleeping mat designed to balance comfort, insulation, and packability. Strategically cored foam construction reduces weight and packed size without sacrificing support, while the recycled ripstop outer fabric delivers durability in a lightweight design. Self-inflating foam insulation provides a flat, comfortable sleeping surface and reliable protection from cold ground, making this mat a practical and high-value choice for backpacking and camping adventures.
