The Mizuno Samurai Baseball Catcher's Face Mask is built to keep backstops protected without weighing them down. This mask is constructed from hollow-construction Chromoly steel, a strong yet lightweight alloy, finished with a reduced-weight powder coating so catchers get maximum protection with minimal fatigue over a long game behind the plate. A built-in throat protector shields the neck from foul tips, while a breathable mesh face liner and adjustable harness deliver a comfortable, secure fit inning after inning. It's a proven, no-nonsense mask for programs that want durable protection at a fair price.

Key features & specs:

• Hollow-construction Chromoly steel frame: strong and lightweight
• Reduced-weight powder coating cuts mask weight without sacrificing strength
• Built-in throat protector for foul-tip protection
• Breathable mesh face liner for comfort and airflow
• Adjustable harness for a secure, custom fit
• Adult traditional profile; Mizuno Style #380438

Coach's tip: check the harness tension before every game so the mask sits stable and clears cleanly on a pop-up. Wipe down the frame and liner after use and store dry to prevent rust and odor.

Add upper-arm coverage to your chest protector with the Pronine 4½-inch Bicep Extensions. Sold as a pair, these padded extensions attach to a Pronine CPU chest protector to shield the biceps from foul tips, backswings, and errant throws — the exposed zone many plate umpires wish their protector covered. It's a simple upgrade that turns a good chest protector into a more complete piece of protective gear.

Key features & specs:

• Bicep extension pads designed for use with the Pronine CPU chest protector
• Sold in pairs for balanced left- and right-arm coverage
• 4½-inch length adds protection to the exposed upper-arm area
• Attaches to the existing CPU harness and shoulder system
• Color black to match your Pronine umpire kit

Coach's tip: Position the extensions so they cover the outer bicep in your set stance, where most foul tips catch you. Care: Wipe clean with a damp cloth after games, air-dry completely, and store flat with your chest protector.

Dial in the fit and coverage of your chest protector with the Pronine 4-inch CPU Extension. Taller officials and umpires who want extra torso protection can add this simple panel to lengthen a Pronine CPU chest protector, closing the gap between the shell and the abdomen so errant balls and backswings meet padding instead of skin. It's a small, inexpensive add-on that makes a well-fitted protector fit even better behind the plate.

Key features & specs:

• 4-inch extension panel for Pronine CPU umpire chest protectors
• Adds vertical length and coverage for taller officials
• Helps close the gap between the protector shell and abdomen
• Attaches to the existing CPU harness system
• Color black to match Pronine umpire gear

Coach's tip: Test the added length in a full crouch before your first game so the extension sits flush and doesn't ride up. Care: Wipe down with a damp cloth after use, let it air-dry fully, and store flat with your chest protector.

Work the plate all doubleheader long with the Pronine Adjustable Umpire's Leg Guards. Built to disappear under your pants while still taking every foul tip and backswing, these guards pair a ventilated wrap-around design with a floating knee cap that flexes naturally in the crouch. Removable, washable liners keep them cool and fresh across a hot season, and the adjustable sizing means one pair fits a wide range of officials comfortably.

Key features & specs:

• Wrap-around, webbed, ventilated mesh padding for airflow and comfort
• Ventilated ABS plastic shin plate with embedded plastic ankle protection
• Floating middle knee cap for exceptional flex, plus a deep wrap-around main knee cap
• Removable, washable, adjustable knee pad and Cool Max shin liner
• Washable and quick-drying; designed for both men and women
• Adjustable 15–17 inch size fits under most makes of umpire pants; color black

Coach's tip: Set the straps snug but not tight so the floating knee cap can move with you through every pitch. Care: Remove the liner and knee pad, hand-wash, and air-dry; wipe the ABS shell clean and store flat.

Get maximum lower-leg coverage behind the plate with the Champro Pro-Plus Umpire Leg Guard. A triple-knee design extends protection up the thigh, while contour-molded, ventilated shin caps shield the front of the leg and keep air moving on hot days. Full calf and ankle wings wrap the sides, and an extra-long hinged instep cap guards the top of the foot — a key feature for umpires who don't wear protective footwear.

Key features & specs:

• Triple-knee design for added upper-leg protection
• Contour-molded, ventilated shin caps for coverage and airflow
• Full calf and ankle wings for wraparound side protection
• Extra-long hinged instep/foot cap — removes with a screwdriver
• Low-profile build ideal for plate umpires who don't wear protective shoes
• SKU: CS-CG385-CG370-CG355

Coach's tip: Take advantage of the removable instep cap — leave it on if you wear plate shoes without toe protection, or take it off for a lighter setup if your footwear already covers the foot. Care: Wipe the caps clean after games, air-dry the straps and liners so sweat doesn't degrade the elastic, and store flat to protect the molded shape.

Step behind the plate with premium protection using the Champro Professional Umpire Gear Box Set. This upgraded kit pairs Champro's PRO-PLUS protective gear with the game-management tools an official needs, delivering a higher level of coverage and comfort than an entry set. It's the smart choice for experienced umpires, varsity-level officials, and programs that want their crew in professional-grade equipment.

Key features & specs:

• Lightweight umpire mask for reduced fatigue over long assignments
• PRO-PLUS umpire chest protector for premium upper-body coverage
• Low-profile PRO-PLUS umpire leg guards for shin, knee, and instep protection
• Wood-handle umpire brush for cleaning the plate
• 4-dial indicator for tracking balls, strikes, outs, and innings
• Professional umpire ball bag to hold spare baseballs and tools
• SKU: CS-CBSUVK

Coach's tip: Ideal for umpires working full varsity or tournament slates — the lighter mask and PRO-PLUS padding pay off over back-to-back games. Care: Air out all pads after each game, wipe the mask and hardware clean, and store the set together so your crew's gear stays complete and ready.

Get a new umpire fully outfitted in one purchase with the Champro Performance Umpire Gear Box Set. This complete kit bundles the core protective and game-management gear an official needs to work behind the plate, taking the guesswork out of piecing a set together. It's an ideal starter package for schools breaking in new umpires, rec leagues equipping their officials, or anyone stepping behind the dish for the first time.

Key features & specs:

• Adult umpire mask for face and head protection
• Inside chest protector for a low-profile, under-shirt fit
• Single-knee leg guard for shin and knee coverage
• Wood-handle umpire brush for cleaning the plate
• 4-dial indicator for tracking balls, strikes, outs, and innings
• Professional umpire ball bag to hold spare baseballs and tools
• SKU: CS-CBSUSK

Coach's tip: Great value for outfitting a first-year official — everything works together out of the box, so a new umpire can focus on positioning and calls instead of shopping for gear. Care: Air out the pads and protector after each game, wipe down the mask and hardware, and store the set together so nothing goes missing before the next assignment.

Work the plate with low-profile protection using the Champro MVP Umpire Inside Protector. This chest protector is built to be worn under a shirt or jacket, giving umpires a streamlined silhouette without sacrificing coverage. Durable compression-molded foam absorbs and disperses the energy of foul tips and rebounding pitches, while armor-plated shoulder caps add extra defense over the most exposed area behind the dish.

Key features & specs:

• Durable compression-molded, energy-absorbing chest protector
• Armor-plated shoulder pads for extra coverage
• Abrasion-resistant braided nylon binding for long-lasting edges
• Rust-resistant nickel-plated steel hardware
• Low-profile inside design for a streamlined fit under clothing
• SKU: CS-CP9

Coach's tip: Adjust the harness so the protector sits snug and high on the chest — an inside protector should move with you through every crouch without shifting. Care: Wipe it down after games, let it air out so sweat doesn't sit in the foam, and hang or lay it flat so the molded padding keeps its shape.

Stay protected behind the plate with the Champro Umpire Outside Protector. This traditional body protector shields the chest, shoulders, and midsection from foul tips and errant pitches, giving umpires confidence to work close and make the call. One-piece polyurethane foam absorbs and disperses impact, while a tough 420-denier nylon cover stands up to season after season of contact and handling.

Key features & specs:

• One-piece polyurethane foam for reliable impact protection
• Tough 420D nylon cover for durability
• Dimensions: 21" x 23.5"
• Built-in ball pocket to keep spare baseballs handy
• Adjustable web shoulder straps with a handle at the waist for easy carry
• SKU: CS-CP07-B

Coach's tip: Adjust the shoulder straps so the protector sits high enough to guard the collarbone but still lets you turn and track the ball freely. Care: Wipe the nylon cover down after games, let it air out so sweat doesn't sit in the foam, and store it flat or hung so the padding keeps its shape.

Add a critical layer of protection to your mask with the Pronine Umpire's Throat Guard. This 4-inch guard hangs from the bottom of your umpire or catcher's mask to shield the throat from foul tips and deflected balls — one of the most vulnerable spots behind the plate. Quick to attach and just as quick to remove, it's an inexpensive piece of insurance no plate official or catcher should work without.

Key features & specs:

• 4-inch hanging throat guard for umpire and catcher's masks
• Velcro attachment for fast on-and-off setup
• Fits Pronine CH1SZ, CHYTH, and CHPRO mask models
• Shields the throat from foul tips and deflected pitches
• Sold separately; color black

Coach's tip: Check that the guard swings freely and fully covers the throat opening before every game — a guard that's ridden up or torn loose isn't protecting anything. Care: Wipe clean with a damp cloth, keep the Velcro free of debris so it holds firmly, and store attached to your mask.

Make every call heard with the Champro Electronic Whistle. A push-button electronic whistle delivers a loud, consistent tone every time — no lung power required — which is ideal for officials working multiple games, coaches running long practices, or anyone who wants a touchless option. It reaches a commanding 120 dB in any direction, cutting through crowd noise and carrying across the field or court.

Key features & specs:

• Loud, consistent whistle tone with each press of the button
• Reaches 120 dB projected in any direction
• Touch-free operation — no blowing required
• Complete with a wrist rope strap for quick access
• Requires 2 AAA batteries (not included)
• SKU: CS-A339

Coach's tip: Great for officials and coaches who work back-to-back games — and the no-blow design is a smart hygienic choice for shared or high-use settings. Choose from multiple tones if your model offers them to distinguish your whistle from a nearby field. Care: Keep it clean and dry, remove the batteries during long-term storage to prevent corrosion, and carry it on the included wrist strap so it's always ready.

Mark the line to gain precisely with the Champro Chain Clip / Yard Marker. This bright orange nylon marker attaches to the chain-crew system to track yardage, giving officials a clear, adjustable reference for measurements and first-down spots. A black plastic slider marks yardage from 0 to 50 in five-yard increments, and the end metal clip fastens securely to the chain so it stays exactly where the crew sets it.

Key features & specs:

• High-visibility orange nylon marker
• Black plastic slider marks yardage from 0 to 50 in 5-yard increments
• End metal clip fastens securely to the chain
• 14" long for a clear, readable reference
• Part of a complete chain-crew measurement setup
• SKU: CS-AF51

Coach's tip: Set the slider carefully at the start of each series so measurements are consistent — an accurate clip is what makes a chain measurement fair and beyond dispute. Care: Wipe it down after wet games, keep the slider moving freely, and store it with the chain gear so it's ready for the next game.

The Champro AF31 is the single-sided, long-neck design in the Champro throw down bean bag lineup — purpose-built for football officials who need a bag that tucks easily into the belt, stays firmly in place throughout the game, and pulls out cleanly and quickly in the heat of a play. The 4" long neck is the defining feature of this model: it gives officials a clear, extended grip point that makes both tucking and retrieval faster and more reliable than standard short-neck designs, keeping the bag secure without fumbling when it matters.

Each bag is constructed from weather-resistant ripstop nylon that holds up through outdoor game conditions — rain, turf, and field debris — season after season. The weighted center ensures the bag drops straight down and holds its position on the ground after the throw, so it marks the exact spot of the foul or line of scrimmage without rolling or shifting during active play. At 3" wide x 6" long x 1/4" thick, the AF31 sits flat and compact, making it comfortable to carry on the belt without adding bulk under the uniform.

The single-sided construction and long neck make the AF31 the preferred choice for officials who prioritize easy handling and speed of access over the double-sided flip functionality of the AF34. Available in white. Sold by the dozen.

Key Features:

• • Model: AF31 — Single-Sided, Long Neck design
  • 4" long neck for easy belt tuck and quick retrieval
  • Single-sided construction
  • Dimensions: 3" wide x 6" long x 1/4" thick
  • Weather-resistant ripstop nylon construction
  • Weighted center — drops straight down, holds position on ground
  • Compact, flat profile — comfortable carry under uniform
  • Available in white
  • Sold by the dozen (12 bags per pack)
  • Ideal for football officials at all levels
