The Inertia X Frame is an ultralight inflatable mattress created by the brand Klymit, located in Utah, United States, and it is practically the most minimalist inflatable mattress you can find.
When to use it
The X Frame is recommended to be used inside a down sleeping bag. It will fill the gaps in the mattress and ensure proper thermal comfort. Some hikers also use it in combination with another foam mat. In this case, you can use it with a quilt or blanket.
When used with a down sleeping bag, it will support you in 3 seasons, including light frosts. If you have a blanket or pillow, you can use it to enhance comfort.

Design
The Inertia X Frame is designed to strike a balance between weight and comfort. It provides support at key pressure points and eliminates every gram of unnecessary material. Don’t be fooled by its minimalist design; this mattress offers a lot of support and comfort for an insignificant weight.
It was created with the human body in mind. Its advanced design places air chambers only where needed and eliminates them where they are not, allowing for weight reduction without sacrificing comfort. It inflates quickly in just 5 or 7 breaths and includes a hand pump for faster inflation. The clever valve design allows for micro-adjustments to adjust the pressure.

Light and comfortable for what one can expect from something so light, ideal for backpackers, bikepacking, etc...
Jaime Toro
Excellent for ultralight and long-distance backpackers. 12-day trip through the Aragonese Pyrenees and it worked perfectly. I love it!
Jonatan Arroyo
I used this on my trip to the Alps and it’s super light. If you put it inside a sleeping bag, it makes it very comfortable to sleep with a high R-value.

I have used this pad on my long-distance outings with great success. It inflates instantly, and I especially like using it inside my sleeping bag. I also sleep on my side, and it has worked well for that too.

Super comfortable and extremely lightweight. The hand pump is much less efficient than using your lungs, but overall, it takes up little space and weighs almost nothing.
