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.

    It stayed perfectly in place even during crazy wind and snow. Super easy to take off, too.

    Everything You Need to Know About Theren™

    Will Theren™ fit my car?

    Yes! Theren is a universal size that fits most cars, SUVs, and trucks. It’s designed to cover the entire windshield and wipers.

    Can it handle snow and strong wind?

    Absolutely. Theren is built with heavy-duty magnets and anti-theft door flaps that keep it secure — even during snowstorms or gusty winds.

    Can someone steal my Theren™ windshield cover?

    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.

    This design also keeps it secure against wind and snow, so it stays perfectly in place no matter the weather.

    Will it actually stop frost and ice buildup?

    Yes. Theren blocks frost, snow, and ice from forming directly on your windshield, so you wake up to a clean glass surface every time.

    Is it easy to install and remove?

    Very. Just lay it over the windshield, let the magnets grip, and close your doors over the side flaps. To remove, just peel it off and go.

    Will it scratch my paint or glass?

    Not if used properly. Theren is made with soft, non-scratch materials. Always lift the magnets instead of sliding them to avoid friction.

    Is Theren washable?

    Yes! Theren is made from waterproof, easy-clean material. You can rinse it with warm water or gently hand-wash it with mild soap to remove salt, dirt, or slush. Let it air dry — it’s ready for reuse within minutes.

     
     
       
       

      ❄️ No More Scraping

      Blocks snow, frost, and ice from forming overnight — wake up to a clean windshield every time.

      💨 Windproof & Secure Fit

      Heavy-duty magnets and anti-theft door flaps keep Theren locked tight, even through strong wind and snow.

      Built for Winter. Made to Last.

      Winter to Summer, One Simple Switch.

      When winter ends, Theren™ doesn’t.

      Simply fold it into its compact storage pouch and keep it in your glove box or trunk — ready for next season. Then, when the summer heat hits, flip it over to the reflective silver side and protect your car from scorching sunlight.

      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.

      Protected by Our 60-Day Satisfaction Promise.

      We’re confident you’ll love how much easier your mornings feel with Theren™ — but if you’re not completely satisfied, you’re protected by our 60-day money-back guarantee.

      Try it through snow, frost, and freezing temps.

      If Theren doesn’t save you time, stress, and scraping, simply send it back — no questions asked.

      Your comfort, safety, and satisfaction come first.

      That’s the Theren™ promise.

      • “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.

        Lucas D. (Verified Buyer)

      • “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!

        Amanda P. (Verified Buyer)

      • “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.
