FAQs

• What is the standard material for baseball pants?

  Double-knit polyester with a dirt-resistant finish is the standard across all levels of organized play. It holds its shape through repeated sliding, dries quickly after contact with wet grass or infield mud, and resists abrasion from clay infields better than single-knit or cotton blends.

• What is the difference between open-hem and pinstripe baseball pants?

  Open-hem refers to the hem style at the ankle (an open finished hem that falls over the top of the cleat), not the fabric pattern. Pinstripe is a color pattern with thin vertical stripes on the fabric. Both are available in most youth and adult sizing. Whether your team uses plain or pinstripe is typically a team-level decision.

• Do baseball pants run true to size?

  Sizing varies by brand. Champro pants tend to run slightly loose in the waist. Mizuno adult pants tend to be longer in the inseam than average. Check each brand's size chart using waist and inseam measurements, especially for team orders where fit exchanges are complicated.

• What is the difference between a knicker pant and a full-length baseball pant?

  A full-length pant falls over the top of the cleat in a traditional modern style. A knicker pant ends below the knee and is worn with stirrup socks showing the traditional striped look. Knickers were the standard style in baseball through most of the twentieth century. Both are legal in all leagues. Style preference is typically team-mandated.

• What fabric is used in baseball jackets?

  Most baseball warm-up jackets use a woven polyester shell with a lightweight bonded fleece or mesh lining. The shell provides wind resistance and some water repellency. The lining provides warmth without bulk. Look for a design with raglan sleeves or articulated underarm panels for full throwing range of motion.

• Are baseball jackets allowed to be worn during games?

  Most leagues allow jackets in the dugout and during warm-ups. Players are typically not permitted to wear jackets in the field or at bat during game action. A long-sleeve performance undershirt visible at the wrist is the most common cold-weather solution during the actual game.

• Can I order baseball apparel in custom team colors?

  Yes. Our custom uniform builder handles jerseys and pants in custom colors with team names, numbers, and logos. Stock apparel in the catalog comes in standard team colors as shown in the product listing. For individual players who need a specific color not available in stock, the custom program is required.

• What is a performance base layer in baseball?

  A performance base layer is a moisture-wicking compression or fitted shirt worn beneath the game jersey. It manages sweat, provides light muscle support, and in cold weather adds warmth without restricting movement. Most baseball players at the competitive level wear a base layer under the game jersey year-round.

• How do I remove clay and dirt stains from baseball pants?

  Pre-treat the stain immediately with a spray stain remover or liquid dish soap. Machine wash in cold water on a normal cycle. Avoid hot water and high-heat drying, as heat sets stains permanently and causes polyester to shrink. Line dry or tumble dry on low. Clay stains from red dirt infields are the hardest to remove and may require multiple pre-treatment applications.

• What are batting practice jerseys?

  Batting practice (BP) jerseys are lighter, looser jerseys worn during warm-ups and pre-game hitting sessions. They preserve the condition of game jerseys and often feature a different design or color scheme. Many teams have dedicated BP jerseys as part of their full uniform program.

• What is the difference between a sublimated jersey and a tackle twill jersey?

  A sublimated jersey dyes the design directly into the fabric permanently during manufacturing. It does not crack or peel. Tackle twill sews cut fabric numbers and letters onto the base jersey and has a raised, traditional texture. Sublimated is now more common for recreational and travel teams due to lower minimum order requirements and more design flexibility.

• Do baseball caps come in fitted and adjustable versions?

  Yes. Fitted caps require an accurate head circumference for a proper fit. Adjustable caps use a velcro, snap-back, or stretch-fit closure that accommodates a range of head sizes. For team orders where measuring every player's head is impractical, adjustable caps reduce the risk of size errors.

• What is a compression undershirt and when is it used in baseball?

  A compression undershirt is a form-fitting moisture-wicking base layer worn under the jersey. It keeps moisture off the skin, provides light muscle support, and adds a layer of warmth in cold weather. Short-sleeve, three-quarter sleeve, and long-sleeve versions are available. Many players wear the three-quarter sleeve under a short-sleeve jersey to show the undershirt at the wrist, which is a common aesthetic in baseball at all levels.

• Are there youth baseball pants with reinforced knees?

  Yes. Most youth baseball pants designed for game use include double-knee reinforcement or reinforced sliding patches. This is one of the most important features to look for in youth pants, as younger players slide more frequently and on more varied surface conditions than older players who choose their sliding moments more selectively.

• How do I machine wash baseball apparel to make it last longer?

  Machine wash in cold water on a gentle or normal cycle. Turn jerseys and pants inside out to protect printed graphics and numbers. Use a mild detergent and avoid bleach on colored fabrics. Tumble dry on low or line dry. High heat shrinks polyester and can cause tackle twill numbers to peel. Following these steps consistently will significantly extend the life of any baseball apparel.
