Hi Mabdoo:
I think you might be getting the fitness gloves confused with the weighted gloves... the fitness gloves from Cathe's site are not weighted and do come in small-lg sizing.
EDITED: post by Carrie is correct, while the Cathe sight does list the Weighted gloves for size, the description states "One size fits most" ~ thanks Carrie
the weighted KB gloves (adjustable weights) come weighted in .5 lb incriments filled bags (1lb per glove) but are a one size fits all/most...
I have the weighted KB gloves and do like them but wish they were designed a bit better. They are only adjustable at the wrist with a velcro closure. the fingers are loops that you slide your fingers and thumb through with an open palm with the weight zipper on the back side of your hand. I use them for KBoxing and they tended to flop around during punches, etc. because while my hands are thick, they are a little on the small side as well... I have had to resort to wrapping a piece of athletic tape around the backside of the glove around my palm to hold everything in place... makes it harder to get off though! but I manage to use what I have.
I plan on using these with STS (as Cathe references microloading gloves) so I will be able to hit some of the inbetween DB weights. these gloves with the open palm make it easier to grab the grip of DB and BB's although without the padded protection of weight gloves...
I have seen other KB weighted gloves on TV that the weight pouch is on the inside palm area and fingers can wrap around the weight during punches, but would make them harder to use for anything but KB workouts.
