Backpacking Tents
A Sibley tent (bell tent) had a circular floor plan some 10 ft to 15 ft across, a single central pole some 10 ft high, and walls about 3 ft high. Guy ropes were connected every 2 ft around the first-rate of the walls - these had to carefully tensioned to hold the pole upright and keep the tent in shape.

Depending on the desired tent size, airbeams can be anywhere from 2-40 inches in diameter, inflated to different pressures. High pressure airbeams (40-80 psi) that are filled Page by compressors are most often used in fewer than shelters, whereas low pressure beams (5-7 psi) are preferred for recreational use. The relatively decumbent pressure enables the employment of a manual pump to inflate the airbeam to the desired level
- Airbeams have the unique essence of bending, rather than breaking, when overloaded
- Tents that convenience inflatable airbeams are structured almost identical to those that use flexible poles.
