I was gonna make a new review thread but since crossdx already did such a detailed review, I'll just add to his.
After using the gloves for about a little over a month I agree with crossdx. The gloves do make better bag gloves than actual sparring gloves due to the hard density foam the gloves use.
As for the dual closure strap system the glove uses, it works extremely well at securing your wrist and with hand wraps its a very snug fit. The only gripe I have about this system is it is extremely hard to get the snug secured feeling on both hands when you are trying to secure the straps yourself with one glove already on. :icon_conf
I also had a slight problem with my gloves where the stitching by the wrist straps was coming loose. I e-mailed Hayabusa about this problem and Craig sent out a replacement pair that same day. Now, if that's not customer service, than I don't know what is! Craig is definitely the man to speak to at Hayabusa. He's prompt, friendly and extremely helpful! :icon_chee After e-mailing him, within a few hours he sent out my package via FedEx and it arrived the very next day. Thanks Craig!!!
I give these gloves a 8/10.
