All round mat



Rab is a brand founded in 1981 by a British climber named Robert Carrington, producing reliable, high quality items for extreme cold environments and alpine climbing around the world. In particular, the down and synthetic fiber insulation (batting), which is also the roots of the company, has a reputation for high technology and detail.

Rab developed the company's first sleeping mat series, making it possible to have a one-stop experience combined with a sleeping bag. Stratosphere 4 is an all-around mat with an R value of 3.8. The 100% recycled Stratus™ R (insulation) is designed to trap air and reduce heat loss through convection. Lightweight construction with air and insulation combine excellent warmth with low weight and minimal pack size.

Comfort details include tall, large air chambers on each side to prevent rolling off during sleep . A grip print is placed on the fabric that is soft to the touch to reduce slipping of the sleeping bag. This hybrid design allows you to maintain your preferred posture for a comfortable sleep. With a low-profile two-way valve, the included large pump sack quickly inflates the mat, and the stuff sack opens and closes from the side for easy loading and unloading. It is a very comfortable sleeping mat that is useful not only in extremely cold environments but also in auto camping. We use mats with an R value of around 3.8 and a thickness of about 8 cm all season. In the summer, go to a summer resort at an altitude of around 1,000m. In extremely cold environments, it is possible to spend a comfortable time with Wanderout / Insulation Sheet 00 and insulation effect.
