ULA AirX on ebay

The Ebay listings are from pretty established Ebay sellers out of Missouri. One is an LEO/Sporting equipment wholedaler . Methinks a Klymit distributor got stuck with a bunch of small and medium packs and these guys got a deal on them. Nothing hokey, just an Ebay closeout deal..

10% discount from retail price isn't that much. I think it is legit.

The eBay ones INCLUDE a Klymit XLite pad (MSRP $85), which ULA doesn't include, so the discount is fairly significant. But ULA's website lists all AirXs as being "Out of Stock", so maybe they're being discontinued.

My puzzlement is about the sizes listed (ULA doesn't make a size "S" in the AirX, but the eBay listing purports to sell one). I've actually asked this question to one of the eBay sellers, and I'll report back if I hear from him.

Edited to add:
Here's what I heard from the eBay seller:

Thank you for contacting us. I am sorry, but I am not sure. Unfortunately, I was unable to locate this information. You may wish to contact the manufacturer directly as they would have the most relevant and informative information for you.

I also contacted one of them and got the same thing, that they are not sure what the size is. Also called up ULA to ask about it, and he said they seemed legit.
