Sea to Summit Women's Comfort Light Self Inflating Sleeping Ma (Regular)

Engineered for women to provide extra warmth where needed for lightweight, all-season comfort and performance. Using the Sea to Summit Delta Core™ technology, the Comfort Light S.I. is for those of us who are looking for the perfect compromise between comfort and weight in a traditional self-inflating foam mat. This mat is a thick, lightweight mat with diagonal supporting foam walls to help self inflate while allowing for a more compact rolled size.

Sleeping Mat Features:

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 and the multi-function reversible high flow-rate valve allows fast and easy inflation and deflation.

• Wider at the hip and narrower at the shoulder
• Anti-slip print on top and base keeps it in place
• Large horizontal triangular cores reduce the weight and bulk without sacrificing support and comfort
• Multi-function high flow-rate valve provides fast inflate, deflate and easy fine-tuning for personalised comfort
• Included Pillow Lock™ system attaches Sea to Summit pillows to mat

Sleeping Mat Specs:

• Length: 170cm
• Width: 53cm
• Height/Depth: 5cm
• Weight: 665g
• R Value: 3.8
• Rolled Size: 14.6 x 27 CM

Sea to Summit technical features:

Using anthropometric data to reveal how best to cater for a woman's size and weight distribution, the way they store heat and the way they sleep (on their side, mostly), the Sea to Summit women's specific mats are wider from hip to knee and narrower at the shoulder. A thicker THERMOLITE® layer in the women's air mats and a unique Delta Core™ profile in the women's self-inflating mats translates to warmer core body zones.

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

Sea to Summit have put a new twist on the 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 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 the air mattresses and pillow.
