I have some Nike 2.5 lb each wrist weights that loop over the thumb and velcro around the wrist as well. They are just enough to add that extra bit of weight for STS and such. I also have an Atlus set of incrimental ankle/wrist weights from 1 to 10 lbs... I bought mine at Fred Meyer for the Nike Wrist weights, and Sports Authority for the ankle/wrist weights... I think they were $15-20...
