Sea To Summit Camp Mat Self Inflating

Durable and comfortable all-rounder.
Delta Core-V technology removes up to 20% of the weight and bulk of the polyurethane (PU) foam of a self-inflating mattress, while maintaining comfort and insulation.
Our unique approach uses sophisticated pressure-mapping data to create the blueprint for our distinctive graduated core pattern. Where extra warmth and support is needed for the body contact areas-shoulders, hips and feet-the core holes are smaller. In the less critical areas, we have removed more foam to minimise the weight and packed size. Delta Core-V technology is used in our Ultralight SI and Camp mat SI models.
Multi-Function S.I. Valve
We have literally put a new twist on our very successful multi-function valve so it specifically addresses the inherent characteristic of self-inflating mats-that is, the problem of the foam trying to re-inflate as you’re packing up.
We’ve engineered the “one-way” inflation valve to be reversible and used it to prevent the mat from drawing air back in. this allows you to roll the mat up as small as possible without fighting re-inflation as you go. This patent-pending valve design has the same slim profile, faster inflation than traditional screw valves, easy pressure fine-tuning and super-fast deflation rate as our air mattresses and pillow.
PillowLock™ System
Easily secure your Sea to Summit pillow to your Sea to Summit mat for a slip-free sleep.
Designed to keep your pillow exactly where its meant to be—on your sleeping mat—our unique PillowLock™ hook-and-loop fastener patches come standard with all our mats from mid-2019.
R-Value
ASTM F3340-18 R-values
An R-value (Resistance-value) is a metric used to rate how effectively your sleeping mat resists heat loss. It’s the only way to know how well your mat will prevent your body heat being leeched away by ground temperatures (which can be a lot colder than air temperatures).
This value can be tested in-house but at Sea to Summit our mats are independently tested at a laboratory to precisely controlled standards.
The new industry standard ASTM F3340-18 testing has now been introduced and all Sea to Summit mats released from 2020 onwards are tested to this standard.
