Facts as the maker states them, read 20 Oct 2026

A Pro Select M-Print glove in the Miami Breeze colorway, 11.5 inches, offered in right-hand throw only. The page describes premium Steerhide, genuine full grain leather and a 3D silicone logo.

Type	Baseball glove
Size	11.5 in What this means Measured from the heel to the top of the index finger. Infielders use smaller gloves (10.25 to 11.75 in) for quick transfers; outfielders larger (12 to 12.75 in); first base and catcher's mitts are measured differently. Tip: Bigger is not better for a young infielder. A glove they can close beats a glove that looks like a pro's.
Leather	Premium Steerhide leather; genuine full grain leather What this means Heavy, durable adult-cattle leather. Stiff at first, lasts for years. Most pro lines use it.
Hand	Right-hand throw

Fit profile

Stated comes off the maker's page; derived is worked out from what the maker states: its words, its leather, its numbers; graded is Patrick's call; unknown means the class is not known yet.

LeatherstatedSteerhide
Break-inderivedStiffDerived from leather type (steerhide / pro-grade wording).
What this means
Pro-grade leather such as Japanese kip or steerhide. Can take weeks to months to break in and a young player may not be able to close it at all at first. Lasts for years once broken in.
Tip: Do not buy a stiff pro glove for a player under 12 unless you are ready to break it in for them.
Closing effortderivedHardDerived: stiff build.
What this means
How hard a young hand has to squeeze to close the glove on a ball. Easy means a soft build and a smaller pattern; hard means stiff leather or a big mitt.
Tip: If your player drops balls that hit the pocket, closing effort is usually the reason, not the hands.
