Premium Materials & Construction

Alton’s Ultralight Closed-Cell Foam Mat is made from premium high-density IXPE foam. Not only is this material highly insulative, it’s also more durable and resistant to compression over time, which equals better performance over the long run. The metallic film on the base reflects radiated body heat back towards you, increasing the overall efficiency of the pad without adding any additional weight or bulk.

Frequently Asked Questions

  • Closed-cell foam mats, also called closed-cell foam pads of CCF mats,  are made from dense foam, typically polyethylene or EVA, that are filled with tiny air pockets. By trapping in the warmth, these sealed air pockets trap warmth act as an effective insulative barrier, preventing heat loss through the ground. 

    Closed-cell foam mats are known for being extremely reliable. Because they don’t have any inflated chambers, there is no risk of punctures or disinflation. They’re usually made from one large piece that either rolls or folds up, making them very fast and easy to use. 

    They typically are lightweight, usually under 500g, but they do tend to be a bit bulkier than inflatable mats. Fortunately, because they’re so tough and weather-resistant, they can be secured outside of your pack.

  • Our Ultralight Closed-Cell Foam is made with IXPE foam, a premium material that has a fine, uniform air-cell structure and higher resistance to compression, so it retains shape and insulation performance for longer. 

    To further enhance thermal efficiency, we’ve used an aluminium film on the base. This bounces radiant heat back towards your body and improves the overall thermal performance of the mat without adding additional weight.

  • Yes, you can sleep directly on this Closed-Cell Foam Mat, but we won’t lie – it’s going to feel firm. Ultralight CCF pads are not known for being the most comfortable option out there, as they only provide a thin layer of cushioning between you and the ground. 

    For this reason, most campers prefer to use it underneath an inflatable air mat, such as our Ultralight Sleeping Mat. Combined with another mat, the Closed-Cell Foam will increase warmth, add cushioning, and give you extra protection against punctures so you never end up sleeping on the ground.

  • For our Closed-Cell Foam Mat, we've calculated the R-values based on our own in-house testing formula that uses a combination of lab-style simulations and field testing.

    However, we’re currently in the process of getting third-party testing according to the ASTM F3340-18 industry standard. 

    Alton’s Insulated Sleeping Mat PLUS was independently tested in April 2025 and returned a result of R6.2, which confirms the accuracy of our internal methods.

    We plan to do further third-party testing on other sleeping mats in our range over the next 12-24 months.
