I am looking into purchasing a good belt. I am a little unsure what to get. I was looking at an Inzer belt, one was 10mm and one was 13mm. I do not compete and the belt would be used for low rep squats and deadlifts only. What is the difference between the two? And if anyone has some input on a belt they think is the way to go let me know and the site you can order it from. Thanks
