The only gloves I have in mind now are:
1- UFC training gloves
2- UFC gloves
3- WEC gloves(I know someone who sells them if anybody wants a pair BTW)
4- CSI Pride-style gloves
5- Fairtex(could someone help recommend which is better between thumb or thumbless?)
When you said Fairtex, I hope you were talking about these:
Fairtex Combat Sparring Gloves from Combatsports.com
You mentioned SPARRING earlier and other than the Fairtex I showed, all of the gloves you named are designed like PRO FIGHT GLOVES. That means the people hitting each other in the face with them are getting paid! There is hardly any padding over the knuckles on any of those. You would have to pay me to let you hit me in the face with anything but the Fairtex's I linked above.
