Super thick Camp Plus Self-Inflating Mat with horizontal Delta Cores delivers plus-sized comfort and warmth for year-round camping. Horizontal Delta coring is a technology pioneered by Sea to Summit. The process removes over 40 % of the foam to reduce weight and bulk but does not compromise comfort and durability.

Features

• 4.3 R-Value is warm enough for all but the coldest ground.
• Plus-size shape and three inch thickness provides ultimate comfort.
• Delta Coring removes over 40 % of the foam to reduce weight and bulk, without compromising durability.
• Robust and abrasion resistant 75D polyester shell fabric with extrusion laminated TPU.
• Flip-over multi-function valve for fine-tuning air pressure, fast inflation and easy

Multi-function valve

• To make inflation and deflation of its air mats easier, Sea to Summit developed the multi-function valve. This valve integrates an inflate port with a one-way valve to prevent air loss before you seal the valve, a rapid air dump deflate port, and a fine tune button to adjust for comfort - all in one compact, low profile unit. It has also been designed to allow easy attachment of a pump, for simpler inflation.

Extrusion lamination

• Extrusion lamination is common in the medical and aeronautical industries, but Sea to Summit pioneered its use in outdoor products. Liquid Thermoplastic Urethane is applied to the face fabric through an extrusion head, where it bonds permanently. The result: Sea to Summit sleeping mats are more reliable and longer-lasting.

Pillow lock system

• The Pillow Lock System comprises of self-adhesive hook-and-loop patches which are supplied with all Sea to Summit sleeping mats (as of Spring 2019). Attached to your sleeping mat, these patches secure your pillow and prevent it slipping – yet they will not snag on clothing or other lightweight fabrics. All Sea to Summit Pillows (as of Spring 2019) are compatible with this system. Existing pillows can be made Pillow Lock compatible by adding an Aeros Pillow Case.
