The Official Spartan Race Glove, designed by Fit Four, had given a solution for zero ripped calluses during the Spartan Race and during your obstacle specific training. They provide two similar Spartan gloves, the Spartan OCR Slit Grip and the Spartan OCR Slit Leather. Both will help you to avoid ripped calluses and aid with your grip strength during the race. You may be wondering which one is the better one. If you have the money, you may go ahead to buy both and test it for yourself.
If you want to save some cash by making the right decision, let me help you to decide. I have personally tested both gloves for Spartan Race and also for Spartan obstacle training. Let me remind you, this is based on my personal opinion and experience.
