market analysis for Brazilian Jiu-Jitsu sports equipment

For our new bjj (brazilian jiu jitsu) brand, we need some information about our competitors. I would like to have a list of all competitors and their Gi/kimono (its a sport suit) models with their technical details (which material, which gsm, which weaves, weight, colour). And if its possible I would like to have information about their market share. which kind of gi is most popular, design character (plain or fancy). Maybe also information which kind of other equipments or other stuff they are selling which are related to bjj (like basecap, keychain, etc...)
