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

Designed to meet the unique needs of female physiology, our Women’s Mats provide increased warmth and sleeping comfort. Featuring a women’s
specific shape that is wider at the hip and narrower at the shoulder, we’ve also developed unique Delta Core™ and Delta Core-V™ profiles to provide extra warmth where women often feel the cold most.

In our Women’s Ultralight S.I. Mat, our Delta Core-V™ graduated pattern uses a mix of smaller holes and solid foam under core body zones to achieve increased warmth. In our Women’s Comfort Light and Comfort Plus S.I. Mats, we adjust the depth and shape of our Delta Cores™ to leave more insulating PU foam intact, creating a warmer core body zone and greater insulation from the outside elements.

  • Wider at the hip and narrower at the shoulder
  • Multi-function, high flow-rate valve
  • Larger vertical Delta Cores™ in non-body contact areas reduce the mat’s weight and bulk
  • Anti-slip print on top and base keeps it in place
  • Lightweight 30D polyester with extrusion laminated TPU used on top and base
  • Pillow Lock™ attaches your Aeros™ pillow to your mat, holding it in place for a slip-free sleep
