Main vestibule attached to G450 body with mesh window installed on front skin

Main bolts onto the G450.

Main connects directly at the G450 doorway zipper. Adds 100 cm of covered floor — one cot crosswise, or a generous gear porch under the canopy.

Main plus one Extension chained for 2-cot lengthwise sleeping interior view

Add Extension for two cots.

Main + Extension = 220 × 240 cm of covered length. Two cots fit end-to-end, or one cot with a full gear vestibule alongside.

Multiple Extension units chained forward from Main creating long covered corridor on grass

Chain more for more length.

Each Extension has its own front skin that accepts the next one. Three, four — the system extends until you run out of ground or stakes.

Compatibility

Gopamir G450 Air Shelter Main Type attaches to G450 body — match Sand Brown to Dark Green
Another Gopamir G450 Vestibule (Extension Type) Extensions chain forward from Main (or from another Extension) — order this product again with Extension Type
Gopamir G450 Vestibule TPU Door Attaches to either Main or Extension front skin in place of the mesh window or the next Extension
G450 body (Extension Type direct attach) Extension Type does NOT attach directly to the G450 body — Main Type is required between them

The Main Type attaches to the G450 body — color-match. The Extension Type attaches only to a Main front skin (or to another Extension in a chain) — it cannot attach to the G450 body directly. The front-skin zipper line accepts one accessory at a time: included mesh window (Main only), TPU door (sold separately), or the next Extension. Swap by unzipping one and zipping in the next.

Included

Vestibule body × 1 (each Type)
Aluminum pole set × 1 (each Type)
Storage bag × 1 (each Type)
Mesh window panel × 1 (Main Type only)

Not included

Mesh window panel — not included with Extension Type (only with Main)
TPU door — sold separately (fits both Types)
Additional Extensions for longer chains — sold separately
G450 body — Main attaches to it but is sold separately

Should I start with Main or Extension?

Start with Main. The Main Type is the anchor that attaches to the G450 body — Extensions only attach forward of a Main (or another Extension). If you're sleeping solo or using it as a gear porch, Main alone is enough. Add Extension Type when you need two cots lengthwise or a longer covered corridor.

Can I attach the Extension Type directly to the G450 body?

No. The Extension Type attaches only to a Main front skin — or to another Extension already in the chain. The G450 body does not accept the Extension directly. If you don't own the Main yet, add it to your order alongside the Extension.

Why doesn't the Extension Type include a mesh window?

The mesh window ships with Main as the default front-skin attachment. The brand's logic is that one mesh window covers any vestibule chain — you move it to whichever front skin needs ventilation that trip. Skipping a duplicate mesh on the Extension keeps the price lower per unit.

Can the front skin take mesh + TPU + Extension at the same time?

No. Each front skin has only one zipper line, so only one accessory connects at a time. Unzip one to zip another — mesh for airflow, TPU for tinted daylight, or Extension for more length. Plan the configuration before pitching.

Can I chain three or four Extensions together?

Yes. Each Extension Type has its own front skin that accepts the next Extension. Chain as many as your site, stakes, and patience allow. The brand explicitly describes the system as indefinitely extendable.

Will it leak in heavy rain?

The fabric itself is waterproof — silicone-coated on both sides. The seams are stitched with waterproof thread and zigzag construction, but not taped (silicone coating prevents tape adhesion). In sustained heavy rain, brand recommends applying silicone seam sealer to leak-prone seams. Same construction across both Types.

How many people can sleep inside?

Main alone: one person, cot oriented crosswise (the 220 cm width). Main + Extension: two people, cots end-to-end (220 × 240 cm covered floor). Main + 2× Extension: three cots, and the pattern continues. Width stays 220 cm — only the length grows per Extension.

Air shipping available for the Main Type?

Yes. Weight-based air surcharge shows at checkout — duties and customs covered, no surprise bills later. Five days versus the standard six-week ocean lead time.

When does the Black color come out?

Marketing photos show a Black variant, but Gopamir has not released it yet. Current available colors are Sand Brown and Dark Green only, on both Main and Extension Types. Black timing not yet announced.
