1 - normal belt (usually 10-15 pounds, 10 pouches, straight form)
2 - a 5 pound thin format (usually supplements/added over the top of the other belts)
3 - the super comfy one that has a lumbar support form (really popular with a lot of freefliers)....
I don't think that's up on the site yet. I'll try to find a picture. I use the lumbar one for RW, don't need weights for FF though. It's getting super popular (not Freeflying, that belt is getting popular with freeflyers)
