    With an R-value of 1.5, most people will be comfortable using this mat in temperatures down to about 7ºC, although this will vary depending on other factors such as the weather conditions, what other sources of insulation you’re using with it, and how sensitive you are to the cold.

  • Our Ultralight Sleeping Mat (R1.5) has been third-party tested according to the ASTM F3340-18 industry standard and received an R-value rating of 1.5.

  • To clean your sleeping mat, follow these steps: 

    1. Inflate the mat and close the valve completely to prevent water from entering the mat. 
    2. Using a suitable outdoor gear wash and damp cloth or sponge, clean the entire surface of the mat. 
    3. Rinse off the mat with lukewarm water to remove soap residue. 
    4. Towel down the mat and then place it on a drying rack in a well ventilated area away from direct sunlight. 
    5. Wait until completely dry before packing it away. 

    For long-term storage, we recommend keeping your sleeping mat unrolled and loosely inflated with the valve open. Store in a cool, dry place away from direct sunlight.

Customer Reviews

Overall rating: 4.6 / 5 from 10 reviews.

I wasn’t sure how this would go because it’s so light and thin. But it’s the most comfortable mat I’ve ever had. I’ve tried three of the big expensive brands and all were plastic-feeling. This one isn’t. And while it’s thinner than the others, I found it more comfortable. Highly recommend

Ultralight Sleeping Mat (R1.5)

After being a loyal Thermarest customer for over 20 years (and I still use my TR matts from 20 years ago), I bought the Alton Insulated Mat PLUS R6 earlier this year and I have to say it its THE best cold weather mat I have every tested and owned - the insulation from the ground is fantastic. This is why I recently ordered the Ultralight Mat R1.5. While the quality of the product is ok, I find the mat uncomfortable to sleep on. I don't know why this mat was designed with so many ridges and valleys - none of your other mats have that profile. If you don't lie perfectly flat on it with your whole body, some body parts will inevitably always touch the ground. The design of all your other mats make sense - this one doesn't. And all these little 'air bubbles' are just not comfy to sleep on. Maybe that was also done to reduce weight - however the mat is not even light. Granted - it's compact compared to my Thermarest ProLite but it's 560gr compared to the Prolite with 450gr while the Prolite is also a lot more comfortable. 110gr is a lot of difference. Yes, it's cheaper so maybe I can't have it all. But tbh, I won't be using it again for above reasons - not comfy and no matter how you move around on it you will always touch the ground somehow.

Ultralight Sleeping Mat (R1.5)

We bought two Alton sleeping mats on recommendation and they were SOO great on their first outing. So light and tiny but when they inflate they’re so comfy!! My 9yr old daughter and I took them out for our first overnight hike in camp. I’m a big fan already and can’t wait to take them out again.

Ultralight Sleeping Mat (R1.5)

I haven’t actually slept on it yet but it seems to be really good quality and kept me off the ground so it should be good. It’s also quite a bit lighter than my other similar style mattress of a different brand. The lifetime guarantee gives me confidence.

Ultralight Sleeping Mat (R1.5)

Banging product. Super light and compact, very easy to set up. Very comfortable in both tent and swag, I have used it over uneven, rocky ground before and it was still comfortable, no tears or damage occurred despite the sharp rocks. Only issue is it can be somewhat finnicky to pack back up, if you have a mate to weigh it down on one end it is super fast and easy, otherwise use something to pin down one end to keep it folded and taught as you roll.

Ultralight Sleeping Mat (R1.5)

Great product. Lightweight yet still comfortable. Only used once so far but was very happy with it.
