Check these out! Neat new hand weights with an "open palm"/"loop fingers" design that's extra easy to put on/take off, and cool to wear (for hands and fingers that tend to be on the sweaty side)! Provides excellent proprioceptive input. Durable lycra, that's double stitched for strength, filled with lead-free steel shot. For left or right hand. XS has 1/4 lb. of weight; Sm has 3/8 lb. of weight; Med. and Lg. have 1/2 lb. of weight. To determine the correct size, measure along the base of the pointer finger to the base of the pinky finger along the palm (MP joints on the palmar size from outer to inner edges). 2-1/4" is an XS; 2-1/2" is a Sm; 2-3/4" is a Med; 3" is a Lg.
