Like its nimble little brother the Inertia X Frame, this Inertia XL is the lightest, most compact and technically advanced camping pad in its category of oversized camping pads. The Inertia XL offers increased support, body mapping, coverage area, tossing room, and even an integrated head cradle pillow. The Inertia XL accommodates more body shapes and sizes with its more neutral body map design. The Klymit Inertia XL offers the same technologies as the Inertia X Frame, such as loft pocket technology, customizable pressurized comfort and support, ultralight and compact, and low volume for inflation. This is the ultimate pad for those looking for a little more comfort and support but still want the smallest, lightest thing out there.
