    The 75D polyester makes for a tougher, more abrasion resistant base, while at 7.5cm thick, the Camp Plus S.I. provides ample cushioning for even the boniest of hips. 
    The high 4.3 R-value also means you can use it all year round

    Multi-function S.I valve
    They’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
    Delta Core
    Delta Core technique is a truly innovative approach to reducing the weight and bulk of the polyurethane (PU) foam core of Self-Inflating mattresses
    Their patent-pending coring process removes up to 40% of the initial volume of the PU foam, retaining enough for optimal support and comfort, while minimising the packed weight and size of the final mattress
    Importantly, this coring technique has the additional benefit of keeping the top and bottom surface of the PU foam completely intact. 
    This ensures consistent warmth along the full length of the mattress, avoiding the vertical holes or frame-like gaps that have traditionally allowed warmth to leach downwards
    The full foam surface also provides significantly improved bonding of the foam to the shell fabrics of the mattress, thereby greatly reducing the chance of delamination
    The shape and size of the Delta Cores are adjusted across the different thicknesses of Sea to Summit's mattresses to ensure strength and durability, while still giving the user excellent support and self-inflating performance
    Pillow Lock 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
    Their unique PillowLock™ hook-and-loop fastener patches now comes as standard 
    ASTM F3340-18 R-value
    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
