Smoke-tinted TPU window installed on G450 vestibule front

Daylight in. Outside view out.

Smoke tint turns the solid front panel into a tinted window. You can read inside without a headlamp at dusk, and check the weather without unzipping.

Close-up of 2-way bidirectional zipper opened from top for ventilation

Open top, bottom, or both.

The 2-way zipper means you can vent heat through the top while keeping the bottom closed against rain — or step out the bottom while the top stays sealed.

Same TPU door attached to both main and extension vestibule configurations

One door, two vestibules.

The zipper geometry is identical on the main vestibule (VM) and extension vestibule (VE). Buy one TPU door and use it on whichever configuration is up that trip.

Compatibility

Gopamir G450 Vestibule (Main) Main vestibule attaches to G450 body
Gopamir G450 Vestibule (Extension) Extension vestibule extends outward from main
Gopamir G450 Air Shelter Not direct — requires VM or VE between body and TPU door
Other Gopamir vestibules TN600 and T720+ use different vestibule geometries — see those product pages

Match the door color to your vestibule color: Sand Brown door for Sand Brown vestibule, Dark Green door for Dark Green vestibule. The TPU film itself is the same smoke tint on both — only the surrounding fabric trim color differs.

Storage bag × 1

Not included

Gopamir G450 Vestibule (Main or Extension)
Does not fit the main body door

Do I need a vestibule to use this door?

Yes. This is a replacement front panel for a Gopamir G450 vestibule (main or extension). It does not attach directly to the G450 body — the vestibule provides the zipper interface.

Which vestibule does it fit — main or extension?

Both. The zipper geometry is the same on the main vestibule and the extension vestibule. One TPU door fits whichever configuration is set up.

My TPU looks cloudy after storage — is it defective?

Almost certainly not. TPU film can develop a temporary white haze when stored in humid conditions — a phenomenon called whitening. The cloudiness usually clears when the panel airs out and warms up. Store dry and flat to prevent it.

Which way does the zipper close?

When you're standing outside the vestibule, zip from right to left. This is the brand-specified direction and keeps the 2-way zipper teeth aligned. The bidirectional design means you can open from the top, bottom, or both ends.

Does color matter — does Sand Brown fit a Dark Green vestibule?

It will physically fit, but it won't look matched. The TPU film itself is the same smoke tint on both color variants — only the surrounding fabric trim differs. Order the variant that matches your vestibule color.

Air shipping available?

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.
