Introducing Arctic Tern Flat Windows by Tern Overland – the ultimate choice for adventurers seeking durability, performance, and style.

These lightweight windows, 60% lighter than standard glass, deliver superior thermal insulation, ensuring year-round comfort in your vehicle or expedition build.

Each window is equipped with a fine mesh insect screen and a reflective blackout blind, both of which can be used independently or together for optimal ventilation and privacy. The blackout blind also boosts thermal efficiency, especially in cold weather.

Designed to regulate interior temperatures, these windows help minimize energy consumption, making them perfect for all-season use. Some models also double as emergency exits—check the reference documents to see if your window qualifies.

Choose between the Classic style with a lighter tint and domed exterior, or the Flat style featuring a darker tint and sleek, contemporary design.

So versatile!

These windows are of excellent quality and come with great documentation. The bug screen and thermal window shade are awesome and easy to deploy. The option to be able to leave the window cracked in a locked position is also a great feature.

Love em!

Thanks to the staff at expedition upfitter, they answered all of my many many questions! I'm beyond happy with the Arctic Tern windows I installed! These really are such an upgrade from all of the alternatives I checked out! I will be back to purchase more.

Good fit and extremely good service!

I'm very happy with my two 450 X 900 mm windows that I installed on my Ford Transit van. The product is exactly as described and the documents (consideration for fitment and installation instructions) are complete, well detailed and very useful. But, most of all, I'm more than happy with the level of service that I experienced with Expedition Upfiter: one of the three windows I ordered was broken during shipping. I was in contact with Katie, that took really good care of the whole claim process. She was transparent and really customer-oriented while resolving this pickle. Finally, while UPS was rather slow fixing this problem (more reactive than proactive...), Expedition Upfitter decided to send me back a new window. Thumbs up! I will definitely do business again with these people!

Great Window

I love this window but wished we got one slightly bigger! Bigger is always better! My husband installed 2 of these windows in our van in an afternoon, I couldn't believe how fast that went! Love the bug screen mesh and blackout ability of these.
