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.

Good condition Amazing read.
Format: Paperback
Amazing book shipped in good condition which is surprising since it's a paper back and most my books I got from Amazon have at least a little damage from shipping. Definitely pick up this book if you make games.

My 22 year-old grandson was incredibly happy with this gift!
Format: Paperback
I can't write a meaningful review of the content of this book, because I don't begin to understand it, however, it was one of the things my grandson requested for his 22nd birthday, and he seemed thrilled to get it and he tells me it's a great book, so I can say whole heartedly, this is a terrific birthday gift for anyone who's into computer games.

More Theory than Actionable Advice on Game Design
Format: Paperback
Not a bad book, but not what I expected going in. I read this for a bookclub like event on twitch. I thought there was going to be actionable advice. Like 'do X to make Y feel". The introduction points out that the book is not about the emotional feelings a player receives from games, and this is true. The book DOES provide a language for discussing game design at a more academic level. It is about the theory of how a game feels, and while I didn't agree with everything Steve wrote it was easy enough to follow the thoughts.
