Outdoor Retailer: All Season NeoAir from Therm-a-Rest


The four-season NeoAir mattress, thicker and warmer than the original NeoAir.

Winter ultralighters, Therm-a-Rest is adding an all-season NeoAir mattress to their sleeping pad lineup.

The all-season version (final name to be determined), uses the same Reflective Barrier and Triangular Core Matrix layers as the original NeoAir mattress, but with two additional layers of reflective barrier, instead of one.

Therm-a-Rest says the two types of layers work together to boost warmth and reduce heat loss in NeoAir pads: The Triangular Core Matrix, which looks and acts like an internal truss system, has hundreds of individual cells that reduce conductive heat loss to the ground by restricting the movement of warmed air; the Reflective Barriers radiate heat back to the user.

The all-season NeoAir will have an R-value of 4.9, weigh 19 ounces, and be 2.5 inches thick. (For comparison, a Therm-a-Rest ProLite Plus has an R-value of 3.8, weighs 24 ounces, and is 1.5 inches thick).

The all season NeoAir will have a much more durable shell material than the original NeoAir, says Kerri Dellisanti of Cascade Designs. The original NeoAir shell has uses 30 denier high tenacity ripstop nylon on its top and bottom. The all-season NeoAir will have a 75 denier polyester top shell and a 70 denier nylon bottom.

The all-season NeoAir comes with a stuff sack air pump and field repair kit, and will be available in July of 2011.

Here's hoping you never need that repair kit, but it's interesting to note that a completely flat all-season NeoAir would have an R-value of 1.5.

No small size?? Wow, serious bummer. Most UL/SUL folks I know use nothing but the small. All you need is from your shoulders to your hips and the small was a perfect size for most folks (I am 6'2 and it is perfect for me).

 

An increase from 2.5 to 4.9 is a very sweet R-value increase! While not (obviously) at the level of the down Expeds, for the weight, that is seriously impressive!

The comparable size (medium) NeoAir has been 13-oz so that is a 5-oz increase in weight for a near-double R-value.

 

So did they happen to mention if the material on the bottom is going to be any tougher?

 

And, are they going to screw over their customers again and not include the stuff-sack for this version?

 

All in all, this together with the Z-lite pad would put you at under 2-pounds and provide way more warmth than 90% of backpackers would probably ever encounter. Could be a good setup. The z-lite for added protection and a bit of softness on the bottom, with this new design, hmmm, might have to buy one of these to put up against my present NeoAir!

Welcome to Trailspace, Redwood Guy.

Thanks for those questions. I passed them on to Cascade Designs and have most of the answers for you below.

At this point they do not have plans to release a small size of the all-season NeoAir, but they're going to check in with the product manager about the possibility and give me more info next week.

The shell material on the all aeason NeoAir is more durable than the original NeoAir. The original NeoAir shell is a 30 denier high tenacity ripstop nylon (top and bottom). The new all-season NeoAir has a 75 denier polyester top shell and a 70 denier Nylon bottom.

The all season NeoAir will come with a stuff sack, which also will act as an air pump. Unfortunately, I did not get to see this in person.

Hope this helps.
