7.5cm Thick Air-Cell Cushioning
Want to maximise your recovery on overnight adventures? A luxurious 7.5cm thick, this Ultralight Insulated Sleeping Mat provides the perfect level of cushioning, support and stability. The secret is in our specialised air-cell technology, which disperses your body weight across the entire surface of the pad for optimal firmness, no matter what sleeping position you prefer. For quick, breath-free inflation, we recommend using our Ultralight Pump Bag (compatible with all Alton inflatable sleeping mats).
Damage-Resistant Construction
Nothing ruins a night in the wild faster than a leaky sleeping mat. Crafted from tough ripstop nylon that’s resistant to damage from punctures, abrasion, moisture and UV, our Ultralight Insulated Sleeping Mat (R4) offers extreme durability at a ridiculously low weight. Not convinced? Just watch the Gear Test, where we see exactly what it takes to puncture our Ultralight Insulated Sleeping Mat (hint: when we say ‘extreme durability’, we mean it).
Adaptable Insulation
With a R-value of 4, our Ultralight Insulated Sleeping Mat is suited to year round use in temperatures down to -1º. For additional warmth and comfort in winter conditions, we recommend pairing your Insulated Sleeping Mat with our Closed Cell Foam Pad (R2). Not sure about R-value temperature ratings? Our blog on sleeping mat R-value ratings explains everything you need to know to make an informed choice.
Better Sleep, Better Adventures
We believe that getting a better night’s sleep is one of the simplest ways to improve your outdoor adventures – and your life. That’s why we’ve put so much effort into creating our best-selling range of sleeping gear for hiking, including this Ultralight Insulated Sleeping Mat. Your camping mat is the foundation of your sleep system, so it’s important you choose the best option for your specific needs. To learn more, read our guide to picking the perfect sleeping mat.
Frequently Asked Questions
-
Our Insulated Sleeping Mat (R4) is designed to be an all-rounder that will provide the warmth and comfort you need for most camping scenarios, from warm summer weather down to about 0ºC.
For below freezing conditions, you can pair the Insulated Sleeping Mat with our Closed-Cell Foam Sleeping Mat, which will give you a combined R-value of 6, or consider investing in the Insulated Sleeping Mat PLUS (R6).
-
Our sleeping mat R-values are currently calculated based on an in-house testing formula that uses a combination of lab-style simulations and field testing.
At the start of 2025, we began the process of certifying our inflatable sleeping mats according to the ASTM F3340-18 industry standard. Our Insulated Sleeping Mat PLUS (R6) was third-party tested in April 2025 and received ASTM certified R-value of 6.2. The other sleeping mats in the range are scheduled to be tested over the next two years.
For more information on sleeping mat R-values, please refer to this guide.

To clean your sleeping mat, follow these steps:
- Partially inflate the mat and close the valve to prevent water from entering the mat.
- Clean the entire surface using a soft, damp cloth and technical outdoor gear wash solution.
- Gently wipe or rinse off with lukewarm water until there is no soap residue remaining.
- Towel off excess water and lay out flat over a drying rack in a well ventilated area away from direct sunlight.
- Wait until the sleeping mat is completely dry before putting it into storage.
For long-term storage, we recommend leaving your sleeping mat unrolled and loosely inflated with the valve open in a cool, dry place away from direct sunlight.
For more information on how to clean and store your sleeping mat, check out this blog.

We have designed our sleeping mat to be highly durable and resistant to punctures (check out this video if you want to see us put it to the test), but if you do happen to puncture your mat, we are here to help.
Our Returns & Repair information page provides a step by step guide on how to find and repair a sleeping mat puncture, as well as common issues that can cause partial deflation, including not closing the valve correctly, cold weather, and natural fabric stretch.
