Mizuno Prime Elite X 12.5" Baseball First Base Mitt: GPEX-30 Custom Broken In Game Ready

The Mizuno Prime Elite X GPEX-30 12.5” First Base Mitt is built for baseball players who want premium performance, modern customization, and a controlled feel around the bag. Designed with Mizuno’s attention to detail, the Prime Elite X series brings innovative features to a traditional first base mitt build.

This 12.5” first base mitt gives players a strong target for picks, stretches, and receiving throws across the infield. The first base-specific design helps create the pocket shape and control needed to secure the baseball with confidence.

The Prime Elite X includes a moisture-wicking back-of-wrist pad to help keep your hand dry during hot days on the field. A dimple-textured palm liner under the middle and ring fingers improves dexterity and glove control, giving players a more precise feel when making plays.

A removable back-of-wrist patch allows athletes to easily change the look of the glove without needing a second mitt. The innovative pull/attach feature also adds convenience by letting players connect the glove to a bag or fence, while also allowing fit adjustments by tugging on the leather pull tab for a more controlled feel during play.

Glove Conditioning Service Details:

You know the routine – your season opener is a week away and that brand new glove on your hand – well, it feels like it’s never going to break in. Balls bounce out of the pocket and you are left wondering how you’ll ever have it ready in time for first pitch.

You can worry no more! At ProRollers, our goal is a simple one. We want your gear to be in PEAK CONDITION long before that critical first game. Our bat rolling service optimizes every hit you make and now our glove conditioning service makes that new glove feel just like an extension of your hand – like it’s been there for years. Nothing beats the feeling of a well-conditioned glove!

Over the years, we have perfected the process of optimizing equipment. There is no guesswork with our Baseball Glove Conditioning Service. We have the entire process down to a science.

Our Glove Conditioning: Quality and Perfection!

Step 1: The right tool for the job: Our shop has six different glove-shaping mallets, and every glove needs something different. Your glove is unique, so it gets special treatment as well. We use each specially designed mallet to break down each glove at its specific flex points, form a pocket, or help break in the palm with a weighted head. This particular working of the leather increases the effectiveness of the manual labor process. Since every glove is built differently, this is where our knowledge and experience come into play. Forming the leather on these proper crease points while holding the integrity of the rest of the glove is the key to success. This process is completed in 4-5 sessions over 2-3 days. Working the gloves by hand, along with our conditioning services, is the key to proper break-in.

Step 2:  Manual Labor:  There is no easy way around breaking a good leather glove; it is all manual labor. We do not use heat, steam, or any shortcuts in our break-in process, so they return feeling 100% natural break-in and not a rushed steam job by your local sporting goods store. We use weights overnight, mallets on the pocket, muscle on the flex points,  and time to perfectly break in the gloves immediately for game use.

Step 3: Hydrate the leather: We apply a small amount of specially formulated glove conditioner to the leather and laces inside and out. This conditioner is absorbed by the glove’s pores, which helps keep the glove in top condition all year. This extra conditioning step helps keep dirt and debris out of the newly stretched-out leather pores. Hydrating the leather will also help the glove last longer as it will resist absorbing water, which can lead to early dry rot. We recommend hydrating the leather at the end of each season to stay ready and prevent dry rot.

Step 4: Proper form: To get the perfectly formed pocket, each glove has 100 weighted baseballs/softballs caught in the web, helping form the pocket and laces. Once the glove has a nice pocket formed, we must ensure it maintains its proper form en route back to you. After the glove conditioning process is completed, we put a ball in each glove and wrap it up with rubber bands prior to shipping it back to you. This ensures the glove holds its form on its way back to you. It is imperative that the glove maintains its form during use and does not collapse when fielding a ground ball. Gloves will not come back floppy rags as this is not a helpful tool on the ball diamond. We take these extra steps to provide the full effects of our break-in process.

Step 5:  Glove Maintenance:  Once you receive your glove back, there is nothing you need to do immediately to use it. Remove the rubber bands holding the ball in place and get the leather accustomed to your hand so it gets the proper fit. Once you have it situated, play catch with it right away so you can feel the softness and squeezability of the glove while getting used to it. After the initial catch, you can put a ball back to keep its shape and put it in your bag for future play.
