I've quietly being buying several items of gear since my return from France. Todays purchase was the Klymit Inertia X-lite sleeping mat. I purchased it from http://www.peteblandsports.co.uk/ very close to work, and staffed by folk who know what their talking about. It has a pack size of 15cm x 4cm and blows up very easily to create a mat 107cm x 46cm x 4cm. Remarkably comfortable to lie on, check out the Klymit website to read the theory on this design. The weight.... only 173g! I can't wait to try it out.
