Astro Long Wide Sleeping Mat

Jump to: Our Verdict / Features / Specifications

A Soft and quiet air mat, made from recycled materials, that packs down small.

Brand says: 

Astro brings lightweight comfort, durability, and much-appreciated slumber to any overnight adventure. This updated model features a full suite of more sustainable materials, with a 100% bluesign® APPROVED, 75D recycled polyester fabric shell and 100% post-consumer recycled Primaloft® insulation.

Astro maintains its legacy lateral baffles, which are more comfortable and prevent the pad from curling under the body. The Pillow Baffle™ at the head end bolsters your camp pillow and helps it not slide off in the middle of the night. Our super-efficient Vortex™ pump sack works seamlessly with our Laylow™ zero-profile, micro-adjustable valve for easy inflation and personalized comfort, and helps keep moisture out of your pad. Astro makes a great go-to pad for adventures anywhere.

Our Verdict

I was impressed by how quiet this mat is, not just to lay on but also, I have found some mats have rubbed noisily on the tent floor, this one seems virtually silent.  Made from a plush 75D polyester, it’s a nice surface to lie on, which feels nice next to the skin.

I like the pillow baffle, a raised baffle that sits under your head. It’s not designed to be used in place of a pillow, the idea is it prevents a pillow from moving around to much.

The Astro series comes with the best pump sack I’ve used. Very large, yet very light, it only took me 4 pumps to fully inflate the mat. One warning, if you aren’t careful when removing the pump, you could fully open the release port, so just a heads up.  

The zero-profile inflation valve has a “one-way” setting, so only air can enter, not escape. As well as a fine-tuning button that releases air, so you can get your desired level of firmness. When you wish to fully deflate the mat, simply pull out the valve and all the air can be released.

ASTM R-Value:

From 2020, there is a new industry standard for measuring the R-value (level of insulation) of sleeping mats – ASTM F3340-18. This new standard is the sleeping mat equivalent to the EN rating for sleeping bags.

You can now directly compare the R-value of mats rated using the ASTM F3340-18 with confidence that is a fair and accurate comparison between mats. In simple terms, the higher the R-value, the warmer the mat.

In general terms, an R-value below 2.0 is for summer use, 2.0 to 4.0 is for cooler 3 season use and 4.0+ is for winter temperatures. This will be also be dependent on your sleeping bag, how cold you sleep etc. Please contact our customer service team if you need advice on choosing the right mat for your activity.
