Sea To Summit Comfort Light Self Inflating Regu...

Sea To Summit

A lightweight, comfortable and durable self-inflating camping mattress.

At only 5cm thick and 600g, this lightweight air sprung camping mattress utilizes Delta Core™ technology, which leaves the top and bottom surface of the foam core completely intact, ensuring even warmth along the full length. The shape of the Delta Cores are adjusted across the mattress to ensure strength and durability, which still providing great support and self-inflating performance.

Anti-slip on top and base of mattress helps to hold your sleeping bag and mat in place, allowing you a more stable, comfortable sleep wherever you are. The multi-functional valve with high flow-rate allows for easy inflation, and easy one-way deflation (which means no re-inflation while you’re trying to deflate and roll it up for packing). This makes life a lot less stressful. Also making life less stressful is the 30-D fabric used, which is compact and lightweight, which reduces the overall weight of carrying.

An R Value of 2.7 means this mat is great for use in summer and most of spring and autumn.


Air Sprung Cells™
Small point-weld divided air chambers which individually absorb pressure and conform to the contours of your body without affecting adjacent cells. The result is a mattress that supports you better than one with ‘tubes’ or ‘baffles’.

Liquid-Extruded TPU Lamination Process
An advanced lamination process which enqures and even and durable bond of the TPU (material which makes up the air bladder) to the face fabric. This process if superior to typical ‘roll-to-toll’ lamination and virtually eliminates the risk of delamination.

Multi-Function Valves
Patent-pending, low-profile multi-function valve allows for easy, fast inflation and deflation and enables the user to precisely fine tune the firmness of the mattress.

Delta Core™ technology
Removes the optimal amount of foam to ensure light weight and reduce the packed volume without sacrificing support or durability, and keeps body contact areas warmer while still offering great support and packability.
