Baseball uniforms are one of the most detail-heavy team orders in sports. Between jersey styles, pants, belts, socks, hats, and customization, a “simple” uniform purchase can quickly turn into a long checklist.

The good news: when you know what to look for, ordering custom baseball uniforms can be straightforward—and you can end up with a clean, consistent look that lasts all season.

At ST1 Sports, we support schools, clubs, leagues, and organizations with custom uniform ordering, team apparel, and bulk fulfillment.

What’s Included in a Baseball Uniform Set?

Most teams order a complete uniform package that includes:

  • Jersey (button-down, two-button, or pullover)
  • Pants (traditional, knicker, or tapered)
  • Belt
  • Socks
  • Hat

Many programs also add:

  • Batting practice shirts
  • Warmups (hoodies, jackets, pullovers)
  • Coach apparel
  • Spirit wear for families

If your program wants to sell apparel to parents without collecting money or managing sizes manually, a team store is one of the easiest solutions.

Popular Baseball Jersey Styles (and When to Use Each)

Full-Button Baseball Jerseys

This is the classic look. Full-button jerseys are popular for:

  • High school programs
  • Varsity teams
  • Travel baseball organizations

They offer a traditional style and tend to look the most “official” for game day.

Two-Button Jerseys

Two-button jerseys are a strong middle ground: clean, modern, and often slightly lighter. They’re popular for youth teams and clubs that want a sharp look without going fully traditional.

Pullover Jerseys

Pullover jerseys are typically the most budget-friendly and easiest for youth programs. They also tend to be durable and low-maintenance.

Baseball Pants: Traditional vs Knicker vs Tapered

Pants are where most teams run into sizing issues. Your choices usually include:

  • Traditional baseball pants (full length)
  • Knicker pants (stop below the knee)
  • Tapered pants (modern fitted look)

Tip: If your program has both youth and high school teams, you may want to standardize pants style across the organization so reorders are easier year to year.

What Can You Customize on Baseball Uniforms?

Custom baseball uniforms usually include:

  • Team name across the chest
  • Player numbers (front and back)
  • Player names (optional)
  • Sleeve patches (optional)
  • Color piping and accents

If your program wants to add sponsor logos (a great fundraising option), we can help with
that as well.

Custom Baseball Uniforms for Youth, High School, and Club Programs

Baseball programs have very different needs depending on level.

Youth baseball uniforms

  • Durability matters most
  • Budget is often a priority
  • Roster sizes change quickly

High school baseball uniforms

  • Consistency across JV/Varsity matters
  • Teams often need home/away sets
  • Fit and appearance become higher priority

Club / travel baseball uniforms

  • Multiple tournaments and travel schedules
  • Often includes extra gear (hoodies, bags, warmups)
  • More frequent reorders for new players

Baseball Uniform Sizing Tips (Avoid the Most Common Mistake)

The biggest uniform problems almost always come down to sizing. Baseball players often wear:

  • Sliding shorts
  • Compression layers
  • Belts
  • High socks

To avoid sizing issues:

  • Collect sizes early
  • Use consistent brand sizing year to year
  • Order a few extras if your roster changes often

Don’t Forget Softball

Many schools and organizations place baseball and softball orders at the same time. Bundling your ordering window can simplify fulfillment, reduce shipping complexity, and make program management easier.
