I have above average hands for my size (185cm, 77kg), but regular wrists. The fit is great. The inner orthopaedic foam really covers the hand and make the fit snug but not tight. The 'strips' of padding along the wrist are very supportive and the wide strap is great.
It's a big, wide pillowy glove. Both weigh 16.35oz, so that's nice for a glove to have the advertised weight. Despite being on weight the physical size of the glove feels cumbersome sometimes.
Unfortunately I have punched through a little bit the padding. (My fault, I used these on the bag for a time. If it wasn't for the New Sporting debacle this wouldn't have happened) I've felt my knuckle land on sparring partners recently so I appear to have aged them prematurely. If i was to buy them again, I would keep a pair only for sparring and have a glove with firmer padding for bags & mitts. I am interested too hear peoples opinions on the Win1 style glove 14oz and below.
As for the Boon gloves, sorry no. I had a pair of Twins 14oz in the past and hated them
