WHAT IT DOES

Four reasons to swap the fabric door.

Smog TPU panel installed on T-250 Air Shelter front showing forest view

Daylight without the bake.

The smog tint cuts UV and tempers glare. Per KZM, five stars on UV blocking vs two for clear TPU panels — interior stays comfortable in afternoon sun.

Inside view through smog TPU window with privacy comparison overlay

Privacy from outside.

Smog TPU dims the view from outside. Per KZM, four stars on privacy vs one for clear TPU. Inner panel restores full privacy at night.

YKK zipper on TPU panel being engaged on shelter door frame

Zips into either tent.

Same open-zipper standard as the T-250 shelter and vestibule. Replace the fabric door with this panel in seconds — no tools, no re-pitch.

Inner panel zipped across the window from inside the cabin

Inner panel for night.

An internal panel zips over the window from inside. Daylight by day, full privacy by night — without packing up the entire door.

SMOG TPU VS CLEAR TPU

Why KZM picked smog instead of clear.

Per KZM's published comparison ratings.

UV BLOCKING

UV blocking — five stars vs two.

Per KZM's chart, smog TPU rates five stars on UV blocking versus two stars for clear TPU. Less fade on fabrics and gear inside the shelter.

PRIVACY

Privacy — four stars vs one.

Smog tint limits the outside-in view. Per KZM, privacy rates four stars versus one for clear TPU — and the included inner panel handles night-time fully.

YELLOWING

Yellowing resistance

Clear TPU yellows visibly over time. Per KZM's rating, smog TPU sees less colour shift — four stars vs one — so it stays looking right for longer.

FREQUENTLY ASKED

Questions, answered.

Where exactly does this install?

On the T-250 Air Shelter (K251T3T28) front or rear door, OR on the T-250 Vestibule (K251T3T30) wall panels. Same open-zipper standard on both — zip the fabric door out, zip this panel in.

Does it work on Albion or other Kazmi tents?

No — this panel is cut to the T-250 module zipper standard only. For the Albion line, see the matching Kazmi AON Albion TPU Window (Smog) — K251T3T27.

Why smog instead of clear TPU?

Per KZM's comparison ratings: better UV blocking (five vs two stars), better privacy from outside (four vs one), better yellowing resistance (four vs one), and reduced interior glare and heat.

Will rain leak through the zipper?

KZM discloses that during persistent or heavy rain, mesh-mount TPU zippers may see minor seepage at the zipper seam — not a defect, but expected behaviour. Most weather is fine.

Does TPU yellow over time?

All TPU yellows somewhat over years — KZM discloses this is inherent to the material. Smog TPU yellows less than clear and disguises remaining shift better thanks to the dark tint.

How does it behave in cold?

KZM notes TPU stiffens at very low temperatures. Handle the panel gently below roughly -10 °C / 14 °F — avoid sharp creases when cold to prevent stress whitening.

What about privacy at night?

An inner panel zips over the window from inside the shelter — full privacy at night while keeping the daylight benefit during the day. No tear-down needed.

FROM THE CURATOR

Why we carry it.

BIGTENT ·Coquitlam, BC

"A lot of TPU-window add-ons on the market are clear plastic that yellows in two seasons and reads cheap. KZM's smog tint solves both — UV protection plus a colour that hides the inevitable material shift. The fact that the panel fits both the shelter and the vestibule is the practical part: one accessory, two installation paths. Buyers who already own the T-250 setup add this for the daylight cabin look; we restock it because the swap-in-seconds workflow actually delivers on the promise."
