I swim 3 times a week for 90 minutes....the gloves grab the water and help propel me through faster...I bought small because I thought after use the gloves would stretch ...I could have used a medium (not a small/medium nor a medium/large)  The sizing is rather confusing..  The velcro closing is rather loose but not loose enough to slip from my hand or wrist.  Overall, the product is pretty good...as an aside, I would rather have them offered in all black.

The mesh fabric allows easier grip when using other pool equipment. I would prefer having the thumb tip opened as with the fingers.

The gloves fit fine however the velcro keeps coming undone during workouts.  Perhaps a button or some other way to secure the gloves would work better than velcro!!!!!
