Rab Exosphere 3.5 Self-Inflating Sleep Pad (665g)

For those seeking a balance of comfort, durability, and user-friendly design, the Exosphere 3.5 self-inflating sleep mat makes an excellent choice. Designed with X-Core™ foam filling, it provides reliable insulation and support, ensuring a restful night’s sleep before the next day’s journey. The foam incorporates advanced X-Core technology, a three-dimensional, weight-relieved structure that not only trims down bulk and pack size but also traps warm air effectively. This contributes to the mat’s R-value of 3.6, enhancing insulation. Its rectangular profile is tailored to suit a range of sleeping styles, offering adaptability in the great outdoors. A low-profile two-way valve allows for swift inflation when weather conditions change suddenly, and effortless deflation when it’s time to pack up.

Crafted from recycled polyester and finished with a fluorocarbon-free DWR coating, the outer fabric is both rugged and soft against the skin. Built for versatility and reliability, the Exosphere 3.5 is a dependable travel companion—an ideal spot to rest, recharge, and wake ready for whatever the next day holds.

Technology

X-Core™

The X-Core™ self-inflating foam system takes the hassle out of setting up camp. Designed for both comfort and support, it features a honeycomb-inspired structure that cleverly balances low weight with high thermal efficiency. By trapping and stabilising air within its core, it offers reliable insulation from cold ground temperatures.

R-value

The R-value of a sleeping mat reflects its ability to resist heat loss to the ground. A higher R-value indicates better insulation, meaning the mat will provide greater protection from the cold beneath and offer more comfort in lower temperatures.
