Coaches love this one: run ST350 tees for players and ST550 polos for staff in the same color, decorated in one order under one setup.

How the ST550 decorates

This is the part most printers will not tell you before they take your money.

Smooth interlock face

Denser and smoother than mesh, so embroidered logos sit flat and printed logos hold detail.

Color that stays put

PosiCharge locks the garment color through commercial washing – team maroon stays team maroon.

Poly handled properly

Like every 100% polyester piece here, it gets low-temperature finishing and low-bleed process on any printed decoration. The fabric demands it; we deliver it.

Match it with ST350 performance tees for the full team package.

Sport-Tek ST550 questions, answered

What is the minimum order on ST550 polos?

24 pieces, with no setup fees. Mix colors and sizes inside that 24 with the same logo.

ST550 or ST640?

Same price class, different fabric. The ST550 interlock is smoother and a touch dressier; the ST640 mesh is the maximum-airflow pick. Outdoors all day, take the 640; front of house, take the 550.

Does it match the ST350 tee?

Yes - same fabric family and PosiCharge color system. Players in tees, coaches in polos, one color, one order.

Can you put ours labels in it?

Yes - the tag is removable, so relabeling with your own brand is straightforward.

Will it fade or shrink?

PosiCharge locks the color and polyester barely shrinks. Wash cold, skip softener, dry low.

Do you ship, or is this local pickup only?

Both. We are in Deerfield Beach and plenty of customers pick up, but we ship orders anywhere in the US.

24-piece minimum. No setup fees. Same-day pricing from a shop that runs this blank every week.
