Why Should You Install Thumb Warmer on ATV

Installing a thumb warmer on your ATV can greatly enhance your riding experience, especially during colder seasons or in chilly climates. Installing a thumb warmer on your ATV will bring you several benefits:

Comfort & Warmth: Riding with cold hands can be extremely uncomfortable and dangerous, affecting your grip on the handlebars. A thumb warmer ensures that your thumbs stay warm and nimble, allowing you to maintain full control of your ATV at all times.

     Prevents Frostbite: A thumb warmer can also help prevent frostbite or other cold-related injuries. Our fingers are more susceptible to numbness and reduced dexterity when exposed to low temperatures for extended periods.
By keeping your thumbs warm with a dedicated warmer, you minimize the risk of frostbite and maintain better control over throttle operation.

  Longer Riding: Installing a thumb warmer on your ATV allows you to extend your riding season into colder months without sacrificing enjoyment or safety.

It enables you to ride in lower temperatures for longer durations comfortably without having to endure freezing hands or limited mobility caused by the cold weather.

What is the best thumb warmer for your ATV? 

Finding a thumb warmer for your ATV need not be that tough, but with a little knowledge, you can avail the best one. There are just a few factors to consider. 

Heated Grips vs. Thumb Warmer

Firstly, you’ll should consider the type of thumb warmer that suits your needs. There are two main types: heated grips and heated thumb warmers.

Heated ATV grips cover the entire handlebar-thumb throttle and provide warmth for your thumbs and your hands, while heated thumb warmers specifically target warming just your thumbs. Heat Demon offers quality products to rely on. 

Power Source

Next, you should consider the power source of the thumb warmer. Some models require a connection to the ATV’s electrical system, while others operate on batteries.

An electrical-powered thumb warmer may be ideal if you prefer a more permanent solution and don’t mind connecting it directly to your ATV’s power supply. Conversely, a battery-powered option would be more suitable if you value portability and flexibility.

Advanced Features

Lastly, take into account additional features that might enhance your experience with the thumb warmer. Some models offer adjustable temperature settings, allowing you to customize the level of warmth according to personal preference or weather conditions.

Others come with a quick heat-up function for instant warmth as soon as you start your ATV. Consider these aspects when deciding which thumb warmer is best suited for your comfort and riding style on your ATV.
