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.

HOW IT CHANGES THE VESTIBULE
Three things to notice once it's on.
Three close-ups of the tint, the zipper, and the vestibule fit.
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.
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.

- Gopamir G450 Vestibule (Extension) Extension vestibule extends outward from main

FREQUENTLY ASKED
Questions, answered.
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.
