Pump valve assemble is a disaster.
- Great support
- Valve leaks
I've owned a Klymit Air Beam for about a year now — it was great. Light, offered excellent support. Then the pump valve failed and the thing absolutely will not hold air. It failed right in the middle of a five-day trip and I was left with a pack frame that would not hold air. No way to fix; hopefully Klymit can/will replace.
2/27/14 Update: I've upgraded from one star to three as Klymit did replace the pump as it was still under warranty. That required me sending the whole assembly back for replacement. Did not go all the way up to three stars as the possibility of failure of this simple little part could put a damper on your whole trip; have a backup — in my case I put the aluminum stay back isn the pack as the weight penalty isn't that bad.
Where to Buy
The Klymit Air Beam is a backpack frame sheet inflated with pressurized air that uses lightweight fabric to create a strong structure. The frame sheet weighs 2.4 ounces without the hand pump, 3.3 ounces with the hand pump. The hand pump can be used to customize the air pressure in the frame sheet.
The Klymit Air Beam offers a variety of advantages over regular frame sheets. It is lighter due to the use of pressurized air, stiffer, more comfortable, allows freedom of movement, increased adjustability and optimal load transfer. At only ¾ of an inch thick, the Klymit Air Beam keeps the load close to the user’s back for a direct transfer of weight to the hips.
Here's what other sites are saying:
Lighter, stiffer, and great load transfer for your pack. The Klymit AirBeam Pack Frame is the solution to allow you to move more comfortably on the trail by replacing your removable pack frame in your current pack. Unique aspects of the Klymit Frame; 1 - This is the first framesheet that has a positive correlation with load. Up to 40 pounds the framesheet gets stiffer as the backpack load increases. 2 - The concept rests that under medium to high pressures (4-10 psi) the framesheet resists horizontal collapse, allowing for chambers of air to maintain vertical orientation and allow gravity to force pressure downward directly to the hips for optimal load transfer. 3 - This is the first framesheet that is vertically rigid to maximize load transfer, but compliant during motion and conforms with the human body during strenuous activity, and allows malleability for simple tasks such as bending over and tying your shoes. 4. This framesheet was designed to increase comfort while decreasing weight, and to sacrifice nothing in rigidity and load carrying capability.
