I didn't know there was a difference. So i guess I'm really no help at all.
Most TMA belts are thinner, and more cheaply made. Cheaper material, less of it, and comparatively poorly constructed.
BJJ/Judo belts tend to be thicker, a lot sturdier, and generally better made.
It's not necessarily that a BJJ/Judo belt is better than a TMA belt, as that's a relative term. They are more suited for grappling arts, and the greater tensions put on them. Wouldn't really be of any benefit to wear a BJJ belt in a TKD class.
Hope this helps.
Yes, very helpful. Would a TMA belt work for Jiu Jitsu? I'm assuming so, but it would just not be as sturdy?
