The world's first heat reflective 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.


This time, we have developed the company's first sleeping mat series, making it possible to have a one-stop experience combined with a sleeping bag. Inosphere 5.5 is the highest peak model equipped with all the technology to correspond to the extreme cold environment of R value 5.5. The design is the world's first heat reflective sleeping bag Mythic Ultra 360 / Mythic Ultra 180 TILT ( heat reflective technology with titanium coating on fibers ) and Stratus™ R (insulation material using 100% recycled materials ). It traps air and maximizes heat loss through both radiation and convection. A lightweight construction using air and insulation provides excellent warmth with low weight and a 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. Together with the Mythic Ultra 360 , this is a model that you will definitely want to experience Rab 's highest peak TILT technology.
