      The Polar Grit X is our favorite Polar wearable of all time. Personally, I’ve never been a fan of the typical Polar “style.” They’ve always been too bulky and odd-shaped for my taste, plus they usually never use industry-standard 20mm or 22mm watchbands.

      Their Vantage Series was a nice upgrade with the round, more watch-like look. Now with the Grit X, you also get the 22mm pin setup, so you have endless options for replacement bands. That’s just icing on the cake, though.

The Grit X has every premium fitness tracking feature you could want, and a nice training software platform to match. The best comparison is to the Forerunner 745 and 945 models. For whatever reason you’re looking for the best Garmin alternative, then look no further.

Best Band Replacement Options...

      For the best options to replace the stock watchband on the Polar Grit X, we put together a list of our TOP 3 WATCHBAND BRANDS. Whether you like sporty silicone straps for fitness or elegant leather bands for formal occasions, all of the top 3 brands have a HUGE variety to choose from. On top of that, they all feature quick-release pins, so you can swap out bands quickly, without having to break out the old watch tool kit.

     The most important part of finding the perfect watchband for a multi-sport GPS watch like the Grit X is to get the best fit when working out. This allows you to take full advantage of their premium heart rate sensor and all of the dependent metrics. The best style of watchband to get that perfect balance of snugness, flexibility, and comfort is the Nylon Hook & Loop Sport Loop variety. Also featuring quick-release pins, you’ll be able to clean and dry the nylon sport loop and let it dry, so it’s fresh and ready to go for your next workout.
