About Theren
About Theren
Theren™ was built for one purpose: to make winter mornings easier. We were tired of frozen windshields, early scraping sessions, and starting the day cold and frustrated — so we created a smarter solution.
Our all-weather windshield cover protects your car from snow, frost, and ice overnight. Just lay it on, secure it with magnets and door flaps, and peel it off in the morning to reveal a clean, clear windshield. No scraping. No stress. No wasted time.
Theren™ is designed for anyone who parks outside, lives in a cold climate, or simply wants to start their day warm and ready. Whether you're commuting to work, getting the kids to school, or gifting a loved one — Theren makes winter a little more bearable.

No — Theren™ is designed to prevent that. It features built-in anti-theft side flaps that tuck securely inside your car doors. Once your doors are closed, the cover is locked in place and can’t be removed without opening the car.

Worried About Theft?
Theren™ is designed with built-in anti-theft side flaps that tuck securely inside your car doors — once the doors are closed, the cover can’t be removed without unlocking the vehicle. This simple but effective design keeps your Theren™ protected from wind, snow, and unwanted hands.
Plus, its discreet look and snug fit make it blend in naturally with your windshield, so it doesn’t attract attention like bulky covers.

“No more frozen mornings!”
I used to spend 10 minutes scraping ice before work — now I just peel this off and drive. It stays tight even after heavy snow. Honestly the best winter buy I’ve made in years.
-
“Still perfect after a blizzard”
We got 8 inches of snow last week and Theren didn’t move an inch. My windshield was spotless underneath. It’s so easy to put on and take off — takes less than 30 seconds!
-
“Got one for my parents too”
My dad hates scraping ice, so I got him one after trying mine. Now he says it’s the first winter he’s actually on time! Keeps the frost completely off. Great quality too.
