Sea to Summit Womens Comfort Plus SI Sleep Mat Large Purple

Designed to meet the unique needs of female physiology, the Women’s Comfort Plus S.I. Mat provides increased warmth and maximised comfort for a great night’s sleep in colder conditions. Smaller Delta Cores under the torso keeps more insulating PU foam intact, creating a warmer core body zone and greater insulation from the outside elements. Featuring a women’s specific shape that is wider at the hip and narrower at the shoulder, the exterior anti-slip print ensures you don’t slip when sleeping on sloping ground. The multi-function reversible high flow-rate valve is designed specifically for self-inflating mats and allows fast and easy inflation and deflation. It also guarantees no more fighting re-inflation as you roll up your mat!

Delta Core technology

The STS Delta Core technique is a truly innovative approach to reducing the weight and bulk of the polyurethane (PU) foam core of our Self-Inflating mattresses The 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 our mattresses to ensure strength and durability, while still giving the user excellent support and self-inflating performance. 

A multi-function valve specifically designed for self-inflating mats

STS have literally put a new twist on their 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. They’ve engineered the “one-way” inflation valve to be reversible and used 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 pillows.
