Question: Why are there 2 options for 12oz - 18oz gloves? Are two different types of gloves being offered for each?
Document: Great gloves, i love using them and although they take a day or two to break in they fit secure and comfortably. i feel like a champion with these gloves and they look great.
I have purchased and used both 16oz to 12oz, and both caused significant pain in my hands after moderate use.
Gloves feel real nice like having two pillows on.I really enjoy training with them. The only problem I had was the color started bleeding after just a week and a half of use and I don't really understand why such expensive gloves would do this. You'd think such gloves would have no imperfection but I guess I'm wrong. Kind of made me think the gloves sent to me might've been fake but then again they feel pretty legit and color is really just a small problem.
The impeccable craftsmanship as well as the premium goat leather reflect the time, care, and love devoted to their construction. The smell of the leather alone is astonishing. Truly works of art.-- The reduced amount of knuckle padding gives these gloves a ton of pop. If you like to feel the impact of your shots, these gloves are what you're looking.-- These gloves will take amount 2-6 months to break-in depending on your training schedule.
Even if you don't have hand problems, I still wouldn't recommend using them as workhorses. They're really not meant for that. However, if you have confidence in your hands then by all means, give them a try.-- The price is incredibly high even with the exceptional quality simply because of the below average utility offered.All-in-all: Great quality but only a good glove not suitable for everyday use
Great gloves
very overrated. i should have went w/ the winnings. these gloves did not meet my expectations for the price at all.
