Sea to Summit Comfort Plus Self Inflating Mat Large Women blackberry

Specifically constructed for luxury-seeking women campers, the Women’s Comfort Plus Self-Inflating Sleeping Mat features Comfort Warmth Zones in the hip and foot area to provide extra support and insulation where women need it most. A 30D stretch knit fabric on the upper surface provides a touch of luxury, while the flip-over multi-function valve makes rolling up the self-inflating sleeping mat really easy.

Delta Core
The Delta Core system maximizes the comfort and thickness of the mattress while minimizing weight and bulk. The patent-pending coring process removes 40 % of the initial volume of the PU foam, giving us a minimal packed weight and size. Importantly, this coring technique has the additional benefit of keeping the top and bottom surface of the PU 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. The horizontal Delta Core technique is used in or Comfort Light SI, Comfort Plus SI, and Comfort Deluxe SI models.

Multi Function S.I. Valve
When you pack your sleeping mat, the foam keeps trying to inflate. For this, Sea to Summit has specially designed the “one-way” inflation valve so that it is reversible and prevents the mat from sucking in air again. This makes it possible to roll out the mat as small as possible without having to fight against re-inflation. Compact and low profile, this valve allows faster inflation than traditional screw valves, offers easy pressure fine-tuning and super-fast deflation speed.
