Sea to Summit Comfort Light Self Inflate SI Mat (Regular)

At 5 cm thick and an R-value of 3.1, you can be sure of a great night's sleep. The Sea to Summit Comfort Self Inflating Mat will give you plenty of insulation for 3-season comfort and still leave you with plenty of room in your pack for everything else. This traditional self-inflating foam mattress is the perfect compromise between comfort and weight.


    • Anti-slip print on base of mat, helps hold your mat in place when camping on sloping ground is unavoidable.
    • Diagonal supporting foam walls help inflate the mattress and creates a more compact rolled mat.
    • Multi-function high flow-rate valve provides fast inflate, deflate and easy fine-tuning for personalised comfort.
    • Included Pillow Lock™ system attaches Sea to Summit pillows to mat.
    • Utilises Delta Core™ technology, which keeps body contact areas warmer while still offering great support and packability.
    • Patent-pending multi function valve twists over to allow the mat to be rolled tightly without fighting re-inflation as you go.
