The Rab Stratosphere 5.5 is a lightweight 4 season insulated sleeping mat. This warm and comfortable mat is suitable for almost all camping expeditions, from basecamp or car camping use to year round backpacking and winter alpinism.

Inside the Stratosphere 5.5 is Rab's Stratus 100% Recycled Polyester insulation. This provides an impressive level of warmth over a standard air filled sleeping mat and will prevent heat loss through convective currents resulting in the mat's impressive 5.5 R-Value. The hybrid rectangular shape provides a large sleeping surface, which is great for side sleepers, and the rounded ends help keep the overall weight down without reducing the usable surface.

The Stratosphere 5.5 is constructed from durable 75D Recycled Polyester with internal TPU Coating and fluorocarbon free DWR that will ensure that the mat dries quickly should any rain get in through your tent. The 2 way inflate / deflate valve means that the mat can be quickly inflated using the included pump sack, then when it's time to move on can be quickly deflated.
