How the ST550 decorates
The part most contract shops leave out of the quote.
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.
ST550 questions from resellers
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 I ship blanks in, or do you source them?
Either one. We are a SanMar PSST decorator, so you can order on your own account and have blanks ship freight-free with no minimum to our dock. If you would rather not carry the blanks, we source and bill them through.
Will the order ship blind under my label?
Yes. Your packing slip, your label, nothing of ours in the box. We can drop ship to your client or straight to their end customer.
