Mainly used for kicking.



It seems like option 1 & 2 are thin, compared to 3 and 4.



Number 4 might not be big enough to protect the upper chest? Just incase a jumping back kick slips. But Option 3 looks abit unpractical and doesn't seem it will absorb the imapct well.



What do you guys think?
