Product Description

From backpackers trying to shed grams to car campers who want glamping luxury, the range of self-inflating mats provide consistent warmth along the full length of the mat in a compact, comfortable, easy-to-use package.

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.

Comfort plus - Dual layer design
Using two high resolution cell layers that can be pressurised independently provides ultimate flexibility in comfort adjustment and protection from rough terrain. Offset for more uniform insulation and cushioning, the Dual Layer design also ensures a level of built in redundancy allowing the mat to function even if one of the layers is punctured.

  • Made of robust, durable 75D polyester with laminated TPU
