The Mad Science behind the Inertia XL: Introducing the Anatomical Body Map, and true backcountry comfort.



Before we started Klymit, we found most camping pads very uncomfortable.  They do not contour with the human body, and allow air to be the least stable under the heaviest parts of the sleeper, or where they need it the most.  They allow air to negatively affect the orientation of the sleeper’s body, and encourage the movement of air by pressure bottlenecks and releases.  There are things about camping pad design that simply make us scratch our head, and make odd faces.

Even still, the “side rails” of our competitors are larger air chambers that collapse easier when weighted, and counterproductive.  The weights of our pads are being chased by companies willing to sacrifice durability for a marketing story, and some just flat out lie about the performance of their pads.

Where others mislead is where we have legitimacy.  Everything we do, every shape, loft pocket, weld termination, taper, or contour, is to support your body while you sleep, and the truth is emerging quickly due to this advanced step forward in camping pad thought.  Straight up, our anatomically body mapped pads, the Inertia XL, Static V, Insulated V, and upcoming V Luxe are the most comfortable and supportive camping pads ever designed.  If you haven’t given them a try, here is why you should:

The Mad Science behind the Inertia XL:  Introducing the Anatomical Body Map, and true backcountry comfort.


We have all been told that there are no straight lines in nature (which isn’t necessarily true.  Once you get to the intra-cellular level most structures are triangular and geodesic, which essentially are comprised of many small straight lines…but I digress.  Here is where our minds were at:

Premise 1:  Support of the body is optimal when matching the contours of the body.

Premise 2:  The human body does not have any straight lines.

Premise 3: The human body does not weight a surface in a linear fashion.

Conclusion 1:  To optimally support the body, then, a straight line, like those on longitudinally and horizontally baffled camping pads would not be optimal.

Conclusion 2:  A camping pad that is designed to contour around and assist the body optimally where it applies the most pressure would be more supportive and enhance comfort.

Solution: The patented Anatomical Body Map only from Klymit.

Our approach here was to take a look at how the human body is structured and reproduce the angles of support as close as possible to the body.  We match the angles of the muscular structure of the human back, and adjoin the angles with a weld shape that better contours and supports the human spine.  The resulting shape resembles a ‘V’ pattern, and it is a more comfortable shape that supports the body better.

The advantages of the Patented Klymit V Shaped Anatomical Body Map:


  1. 1.    Air Dispersion:  This body map naturally disperses and deters the movement air, making an inflatable pad more comfortable, more stable, and more supportive.
  2. 2.    Deep, Shaped Welds: One glance at any of our camping pads and it is easy to see the difference in our welds vs. any of our competitors.  Our welds are deep, and shaped in this body map, with varying widths and tapers.  This allows us to do so many things, and combined with our superior welding technology equals a more comfortable and durable pad with lightweight fabrics.
  3. 3.     Thermodynamic Efficiency:  We distribute heat across the channels and use both loft pockets and the weld channels to more efficiently capture and retain warmth.
  4. 4.    Volume Control:  We customize the volume of air in the pad and make it take only a few breaths to inflate, drastically increasing functionality and decreasing setup and take down time.
  5. 5.    Dynamic Flow Control: We disperse the air to desirable places to add comfort while you sleep and move on the pad.  In this body map we focus the air towards the side rails, making them work effectively to have higher pressure as you approach the edge.  This naturally pushes you back to the center of the pad, and keeps you locked in all night long.
  6. 6.    Dynamic Movement:  “The Fish Tail Effect”  This is the only pad that is designed to flex with you while you sleep in the fetal position.  It hinges at the point of the knee, and really does curl up with you.
  7. 7.    Anatomical Neutrality:  Like the Inertia X Frame the design of the anatomical body map inhibits the movement of air into your lower back causing it to arch, and disallows the weight of your torso to cause your legs to elevate.  This keeps you more comfortable and gives your body the relief it needs to recover and truly rest.
  8. 8.    Ergonomic Head Cradle:  The built in pillow cradles your head comfortably, and supports your spine completely.  Your body stays supported, and neutral.
  9. 9.    78 inches by 26 inches  and one pound: Huge real estate with itty bitty weight…awesome!


Klymit’s anatomical body map, when combined with the well thought out creature comforts of the Inertia XL, yields a massive sleeping surface that, upon waking in the morning, will make you realize how far camping pads have come.
