Sea to Summit Comfort Plus Self Inflating Sleeping Mat

Note: This is a bulky product so shipping rates us for more info.

Sometimes, the extra weight associated with a more comfortable nights sleep pays for itself many times over. Built wider than their mummy shaped cousins, our Comfort Plus™ S.I. Rectangular Mats are designed to maximise comfort and warmth for cool-climate treks. At 8cm thick and a winter rated R-Value, our Comfort Plus S.I. Rectangular Mats provide luxury in a packable size. A 30D stretch knit fabric is used on the top layer for a great next to skin feel, and a lightweight 30D polyester with extrusion laminated TPU is used on the base for increased durability. All our self-inflating mats feature our unique, multifunction reversible single valve, designed specifically for self-inflating mats. No more fighting re-inflation as you roll up your mat!


  • Delta™ Core™ Technology
  • Anti-slip print on base of mat, helps hold your mat in place when camping on sloping ground is unavoidable
  • Luxurious 30D stretch knit fabric for a soft next to skin feeling on top
  • Lightweight 30D polyester with extrusion laminated TPU used on base
  • Large horizontal triangular cores reduce the weight and bulk without sacrificing support and comfort
  • PU foam is thicker on top of each Delta™ Core™ for better insulation directly under you. It also keeps top and bottom surface of foam intact ensuring consistent warmth along entire length of the mat and better bonding with shell fabrics
  • Diagonal supporting foam walls help inflate the mattress and creates a more compact rolled mat
  • 8cm thick
