This is an upgraded set, so you can feel confident that your child is being well protected. Our Pro advice for a lacrosse player that is just starting to play: Gloves - need to be mobile and have thinner palms so new players can get a good feel for the stick. Even in the backyard, when not at practice, new players should practice in their gloves. Arm Pads- must have a top velcro attachment - most younger players have trouble with pads sliding down the arms. These Under Armour pads have nice, adjustable straps that close on the tops of the biceps and keep the pads secure. Shoulder Pads - Good sternum protection and plastic coated caps. Must have nice material to wear next to skin, not cheap stuff. Full range of arm motion and ability to have helmet mobility.
