Klymit Inertia XL Inflatable Sleeping Pad

Item # KLYA1404

Availability: Out of Stock

Despite its generous 78" x 25" dimensions, the innovative Klymit Inertia XL inflatable sleeping pad weighs just 16.8 ounces and has a packed size barely bigger than a standard water bottle (4" x 9"). The Inertia XL is ideal for 3-season backpacking.


Despite its generous 78" x 25" dimensions, the innovative Klymit Inertia XL inflatable sleeping pad weighs just 16.8 ounces and boasts a packed size of 4" x 9". Taking up only as much space in your pack as a standard water bottle, the Inertia XL is ideal for 3-season backpacking.

The body mapping construction of the Inertia XL ensures that you have padding where you need it most, while stripping away weight in other places. The cut-away "Loft Pockets" help to lower weight and bulk while effectively capturing the heat of your body. Strategic baffle placement makes the Inertia XL surprisingly supportive while inflating quickly and easily. For those who like their pad as firm as possible, Klymit includes a Dry Air Pump to help you "top off" pressure after mouth inflation. The welded pattern enables the Inertia XL to deflate quickly and roll up in just seconds so you can get on with your adventure.

The Inertia XL is a full 1.5" thick when inflated and its full dimensions are a sprawling 78" x 25". An integrated Head Cradle provides extra support, warmth and comfort. The Inertia XL is built for 3-season use but can also be used in tandem with another pad for snow camping or winter backpacking.

Constructed of 75D polyester, each Klymit Inertia XL inflatable sleeping pad includes a Dry Air Pump, a patch kit and a stuff sack.

Likes: What I like most about this product is that you no longer have to sacrifice comfort and durability for pack weight! It's surprisingly really comfortable. Size of pad is perfect - I'm 5'9", 175lbs.

Dislikes: Nothing

Likes: Great compact design is true spacesaver and lightweight. Works well when put inside sleeping bag, especially effective when using a Hennesay Explorer Deluxe Hammock. Especially liked the small hand inflation device provides adjustment to pad effortlessly.

Dislikes: Although it only takes a couple of full breaths to fill, the humidity of breaths may be problematic over time.

Likes: This is one of the most comfortable pads I've used. I took it on a Scout backkpacking trip and it was wonderful. It rolls up compact and is super lightweight. I'm a big guy and it was plenty wide enough for me.

Dislikes: nothing.
