Wilson youth first base mitts are intended for a younger, more advanced ball player who is looking to take their game to the next level. For the 2018 season, the A900 series is just what the doctor ordered to help get an edge on the diamond. Each model offers a cool, old-school look with the dark brown, full leather construction that comes game ready with absolutely zero break-in period. If you're sick and tired of having a sore wrist and knuckles from an extensive break-in, the A900 is just what you need. From day one, these mitts are ready to go when you are.
