Baseball First Baseman's Mitts

First baseman's mitts typically range from 11.5" to 13"; choose larger sizes for adult play and smaller sizes for youth. Try the glove on for a snug but comfortable fit with enough pocket depth to scoop throws; consider hand length, brim width, and whether you prefer a break-in-ready glove or stiffer leather for long-term shaping

Synthetic mitts are lighter and cheaper but less durable, split leather offers a balance of cost and durability, and full-grain leather provides the longest lifespan and better feel but requires more break-in and costs more. Choose based on budget, how often you play, and how much break-in and maintenance you’re willing to do

A deeper pocket and a closed or modified web (e.g., H-web, basket) help secure throws and scoops, while extra palm and thumb padding protect against hard catches. Look for reinforced lacing and a slightly longer cuff for reach and stability

Prices vary widely by material and brand; budget options can be found under $50, mid-range split-leather mitts commonly range from about $50–$150, and full-grain professional-style mitts often go above $150. Average prices in many selections tend to fall in the mid-hundreds for adult full-leather models

Break in new leather by applying small amounts of glove conditioner, playing catch, and using a mallet or ball in the pocket to form shape; avoid over-oiling. Maintain by wiping off dirt, reapplying conditioner sparingly a few times per season, checking and replacing laces as needed, and storing in a cool, dry place with a ball in the pocket to retain shape

Yes—buy a mitt that fits the hand you catch with: right-handed throwers wear a mitt on the left hand (often labeled ‘RHT’), and left-handed throwers wear it on the right hand (often labeled ‘LHT’). Confirm product labeling before purchase to ensure correct orientation

Youth mitts often use lighter or synthetic materials to reduce break-in time and weight, have shallower pockets for smaller hands, and sometimes feature adjustable straps for fit; adult mitts prioritize durable leathers and deeper pockets for higher-level play
