When I began my martial arts journey I received a "free" 6 oz. martial arts gi. After a year of training with it, it literally felt like I was wearing a piece of paper. A couple months ago I bought an 8 oz uniform, it was much more crisp, and my techniques had a louder snap when being performed. i really like it. There are also 10, 12 ,and 14 oz. uniforms. What are your personal favorite and why (oz wise)?
