That's a total rubbish. Yes, Reyes use different padding. But only in their fight gloves (safetec/horsehair) and AIBA (molded foam). Their training gloves all have the same latex and the different density of it is because the gloves are handcrafted and the nature of latex - even the 2 gloves in a single pair are sometimes softer/denser comparing to each other. Filling gloves with latex is totally different from using IMF - very often the gloves are not of the same density. Very usual in case of Reyes.
So, the 4 kinds of padding are: 1) latex (sparring/training/bag gloves - lace up and velcro), 2) horsehair (fight gloves), 3) safetec (fight gloves), 4) molded foam (AIBA gloves).
Guys, stop confusing people. Reyes training/sparring gloves are all latex, but it is common with Reyes they do not feel all the same, but you cannot find out it other way than trying a particular pair.
Solved.
