Quick Summary
The Sea to Summit Camp S.I. Mat is a rectangular wide sleeping mat in Light Green. It is a foam sleeping mat with a stated thickness of 1.5 inch and an R value of 4.2, making it a clear option for buyers who want an insulated mat with extra sleeping space.

Who This Product May Suit
This mat suits buyers who want a rectangular sleeping surface rather than a narrower shape, and who value a thicker foam mat with a stated insulation rating. It is relevant for camping, backpacking and scouts, where pack size and sleeping comfort both matter.
Before You Decide
Check the rectangular wide size against your sleeping space, confirm the 4.2 R value matches the conditions you plan for, and make sure the included accessories are the ones you want. The mat is a specific size and shape, so it is worth confirming those details before choosing an offer.
