Peak 38

Thanks to a combination of size, the tapered leg area and perforation with vertical and horizontal cavities, the Peak 38 is our lightest and most packable sleeping pad suitable for cold, winter weather. Right now you’re probably imagining foam that resembles Swiss cheese. That’s not the case. Double perforations were only used in less exposed areas - i.e. under the legs and head, horizontal perforations are used in the body area, which has better insulating properties. The silicone Pinguin logo on the top of the sleeping pad prevents the sleeping bag from slipping and sliding.

Peak sleeping pads are most suitable for users with a smaller and slimmer physique. If you have a bigger build, we recommend the Matrix 38 sleeping pad, which has identical features with a larger surface area.

To prevent air leaking through the pad’s top material, an impermeable membrane has been laminated to the polyester fabric. Laminating a continuous membrane instead of applying a coating eliminates the risk of uneven coating in areas where the material is uneven. This can lead to insufficient coating being applied and air leaking out in the affected areas. The use of PU foam with a thermally laminated membrane (TPU) is the highest quality combination of materials on the market today.

The core of every self-inflating sleeping pad is the inner foam. Pinguin sleeping pads are filled with Polyurethane foam, whose open pores retain air, thus giving it excellent insulating properties. The foam has a very good shape memory, which helps it inflate rapidly and means it does not sag even after years of frequent use.

Nylon valves are intentionally used on Pinguin sleeping pads. The reason for using them instead of brass valves is that they are 100% air-tight due to the material’s partial elasticity, their low weight and greater resistance to freezing. The nylon used on the valves is sufficiently strong and tough.

The combination of horizontal and vertical cavities means the foam in the sleeping pad is as light as possible. In the most exposed zone (from the shoulders to the buttocks), this type of sleeping pad is lightened by horizontal cavities only, which also guarantees the best insulating properties. Sleeping pads with this type of construction are the lightest version suitable for four-season use.
