Train More. Feel Less Impact.

Reinforced with Kevlar laces and built with a foam core, these are designed for high-rep training without beating up your hands, bat, or body.

Why It Matters

Real baseballs wear you down over time. These reduce vibration and impact so you can train longer and safer. For pitchers, they’re ideal for high-volume throwing, machine work, and building mechanics without the same stress on your arm.

Key Features

• Kevlar-reinforced laces for durability
• Foam core for vibration dampening
• Bat-friendly design
• Pitching machine ready
• Premium cowhide covering
• Slight “give” for safer reps

The Bauer Outage Middle Finger Glove is a 12-inch pitchers pattern built to the exact specs Trevor Bauer takes to the mound, not a retail version of it. Every detail, from the leather to the lacing, exists for one reason: making life harder for hitters.

• Reinforced Lacing Durability: Back finger lacing does double duty, hiding the ball deeper in the pocket while reinforcing the fingers against breakdown across a full season of work.
• Authenticated Game Spec: Gold Trevor Bauer palm stamp and NO MERCY wrist embroidery mark this as the unmodified glove, not a softened, cheaper clone built to hit a price point.
• Palm Protection System: Extra palm padding cuts sting on impact and extends the life of the leather, built for pitchers who actually catch return throws all game.
• Pro-Issue Japanese Kip Construction: Built from the same Japanese Kip leather Trevor wears in games, with the FAH cutout cut straight into the web, not stitched on after the fact. This is the pro-issue glove itself, no consumer downgrade in the build.

This includes a free limited Bauer Outage Graffiti Tee, only available with the glove.
