Rab Ultrasphere 1.5 Inflatable Sleeping Pad

Product detailed description

The Rab Ultrasphere 1.5 is a lightweight summer version of the popular Rab Ultrasphere 4.5, which won the prestigious ISPO Awards in 2023. Its thermal resistance is R = 1.3, clearly making it ideal for summer activities.

Sustainability

As a climate-neutral company, Rab naturally uses recycled materials in its production. The outer material is recycled 20D polyester with an inner layer of TPU and DWR fluorocarbon-free. The outer fabric also features a gradient print that helps keep the sleeping bag in the same position.

Simple and quick inflation

Rabu really nailed the valve. It’s located at the bottom of the mat near the head; it’s flat and therefore doesn’t get in the way at all. To inflate, simply flip open the first cap and you can start inflating right away; in this case, air enters the mat in only one direction (it cannot deflate). When you want to deflate the mat, just flip open the second cap and the air is out in a second. Deflating is surprisingly easy and fast. The package also includes a great inflatable bag. In our opinion, it’s the best inflatable bag we’ve ever seen. It’s huge, but weighs only 71 grams. It’s incredibly easy to pump air into it, it has taped seams, and you can easily turn it into a fully functional waterproof bag that you can use, for example, as a cover for your sleeping bag. You can inflate the mat in about three pumps. Easy and fast—we give it 10 out of 10 here.

Great cover

Another thing Rabu really nailed is the perfect sleeping pad cover. It works completely differently from all the traditional covers from other manufacturers. It’s essentially a simple pouch with an elastic hem; you can easily slip the rolled-up mat inside, and the opening is covered by a simple “lid” with integrated elastic bands. There’s no struggle when packing. Packing is truly a breeze. Inside the pouch, you’ll also find a small pocket with a repair kit.

Dimensions

It comes in two sizes. The Regular is the standard 183 x 51 cm with a mummy shape. The Long Wide version is ideal for taller people thanks to its dimensions of 196 x 64 cm. Both versions are the same height—a wonderfully comfortable 8 cm.

We recommend placing Tyvek under every inflatable sleeping pad, as it significantly reduces the risk of punctures.
