NeoAir® XTherm™ NXT Sleeping Pad

Thermarest claim it’s the best warmth-to-weight ratio of any sleeping pad ever made! It is the go-to air mattress for cold weather expeditions with an R-value of 7.3.

With cutting edge Triangular Core Matrix™ construction and ThermaCapture™ technology, the XTherm NXT delivers a 7.3 R-value while weighing just 440 g (15.5 oz) in the Regular size. Put another way, the best warmth-to-weight ratio of any sleeping pad ever created. It is warmer and thicker than the previous model, which is why the XTherm NXT cements the legacy of being the go-to sleeping pad for alpinists, mountaineers and extreme cold expeditions. At 3-inches thick, with horizontal baffles, all-night comfort and support are at hand, while 70D nylon on the bottom ensures the XTherm NXT holds up to extended expedition use. The WingLock™ Valve allows for rapid inflation and deflation but is also intuitive and easy to use in frigid weather when the gloves are not coming off. If reliable overnight warmth is the demand no matter how far the mercury dips and space in the pack is at a premium, there’s no finer sleeping pad than the XTherm NXT.

  • Best Warmth-to-Weight Ratio Ever: Refined Triangular Core Matrix™ construction and ThermaCapture™ technology deliver a cold-conquering 7.3 R-Value while a Regular size weighs just 15.5 oz (440 g).
  • Premium Comfort: A 3-inch (7.6 cm) thick profile and horizontal baffled structure delivers premium backcountry comfort while keeping the weight to a minimum.
  • Ultralight Durability: 70D nylon on the bottom withstands the wear and tear of extended expedition use, while 30D ripstop nylon on top keeps it light and packable.
  • WingLock™ Valve: Delivers fast one-way inflation and rapid deflation without giving up the ability to easily purge air while you lay on it for comfort micro-adjustments—even with gloves on.
  • Multiple Sizes: 3 size options allow you to get the XTherm NXT that is perfect for your sleep system.
  • Pump sack, stuff sack and field repair kit included.

Horrible, don't buy
Size: 1.8in for Puppy Dogs
I wanted to love these. They had so much potential. It's a good size. It seems like a good shape. But ... 1) first red flag should have been the packaging. It looked like it was a dollar store item that had beenblost on the shelves for years. 2) the rubber is super flexible. I was expecting it to be sturdier. I can flatten the ball without lich force. Maybe that doesn't matter. Naybe flexible is good. But I never got a chance to test out it's durability against a pup because... 3) it smelled. I expected it to smell like rubber, like most rubber toys. Rubber smell is okay. Usually rubber smell goes away. But, this was NOT a rubber smell. It smells like peppermint or something similar. It's like someone sprayed essential oils when mixing the rubber and now the smell will not leave. I soaked it in dawn soap half the day and overnight. I rubbed. I scrubbed. The smell actually gets worst the more you scrub it!!! It's like a scented marker or scented eraser, but you do NOT want the scent in a dog toy! My dog cannot smell the food in it because the smell of the weird mint-like scent is so overpowering. He saw it had food, and wanted it, but every time he started sniffing wildly, he would recoil. Whoever thought it was a good idea to scent this was WRONG. Mint in the form of an essential oil is extremely poisonous to dogs!! So, why they would put a mint-loke scent ijto the dog's rubber treat toy is beyond me. I would return this if I hadn't throw out the package immediately. I considered pulling the package out of the trash once i realized the scent issue but other trash had already been dumped into the trash can over it and i didn't want to dig through trash. The ball is still soaking in soap. I scrubbed again this morning. I let obe dry out. No luck. It actually seems to get worst the more you scrub, like it really is embedded in the rubber itself. Yuck!!!

Excellent, unless your pup is a dedicated destructo-dog!
Color: Yellow and Orange
I purchased this twice for a young puppy. She loves these slippers, and they are quite resistent to her piranha teeth. The same can't be said for my adult Golden Retriever, who destroys almost every toy; it's one of his missions in life. A slipper accidently found its way to him, and he shredded it within about 45 minutes. I have to say that I'm surprised it lasted that long, attesting to its relative durability. Overall, I recommend these for most dogs.

Dangerous.
Color: Purple
Died in about 2 days. Dogs chewed it to bits and then tried to swallow the pieces. Would not recommend for pet safety. I don't have big dogs, I have littler puppies (3 and 5 months) - would likely have died instantly with big chewers.

Disappointed they didn’t hold up long before pieces was being chewed off.
Color: Yellow and Purple
My minature poodle loved them till she started chewing pieces off of them so we had to dispose of them.
