      Feather light mattress that offers a solid performance

      I recently purchased the Sea to Summit UL Insulated mattress and used it on a fast and light trip last weekend. I was amazed at its performance - its clever design means it feels just as comfy as a mattress twice its weight and thickness. It is now my tool of choice for getting a good night’s sleep on my bike-packing and back-packing missions.

      sea to summit sleeping mat

      I have found the Sea to Summit UL insulated sleeping mat a perfect item for a great nights sleep after a long day in the saddle. It packs down very small, is light, comes with a blow-up bag & is very comfortable

      Great mat for cycling trips

      A fabulous small light and compact mat that is sooo easy to inflate. Great for cycling trips when you are camping somewhere different every day.
