Air-column expansion
Both listed sections use a pump-assisted Ø15 cm air-column frame after the tent is unfolded and connected.

This 8 + 8 m² expandable polycotton inflatable tent uses 210 g polycotton in Green, with air-column expansion and a skylight. Each tent includes a compatible air pump and a confirmed 3000 mm complete-tent waterproof rating for campsite, rental and wholesale projects.
The pitched configuration is 320 × 250 × 220 cm + 320 × 250 × 220 cm. The 220 cm figure is the peak height and does not apply across the whole interior.
The listed 8 + 8 m² area describes a main body and an air-column expansion. Listed capacity is 10 or more people. Listed weight is 31 + 12 kg for the two packed sections.
The outer fabric is 210 g polycotton in Green as shown, with a double-layer PVC groundsheet and a Ø15 cm / 0.52 mm air column. Compare this expandable format with other camping tents, large group camping tents and inflatable camping tents.
Shared capacity, campsite-fit, setup, waterproof-evidence and repair guidance is in the 8 + 8 m² polycotton family guide. Compare the distinct IT020 structure.
