If you're looking for a lightweight sleeping pad but don't want to compromise on comfort, durability, insulation or ease of use, look no further than the Sea to Summit Ultralight Insulated inflatable mattress. The Air Sprung CellTM technology delivers stability and support, while 40D/30D nylon with antibacterial treatment help prevent delamination caused by moist air trapped inside the mat for better reliability. What's more, Thermolite® and Exkin Platinum® combined insulation delivers the warmth of an ASTM standard R-Value of 3.1 - just perfect for late spring through to early fall camping.
