Shoulder Pad Sizing :

Measure the player's chest just below the arm pits.

Match the player's chest size to the shoulder pad that corresponds.

The bicep pads should not interfere with the player's elbow pads

The center of the player's shoulders need to line up directly with the center of the shoulder cups to protect the shoulder joint

Lifting the arms above the head should not push the shoulder pads uncomfortably high around the player's neck
