How the ST640 decorates
The part most contract shops leave out of the quote.
Built to breathe
The flat back mesh is the whole point, noticeably cooler than a standard polo. Landscapers, valet, outdoor events, patio staff.
PosiCharge keeps it looking new
Color-lock technology means team colors stay bright and logos stay crisp through commercial washing.
100% poly, handled properly
Heat-sensitive fabric gets low-temperature finishing, and any printed decoration runs with a low-bleed process so dye stays out of the design. Standard here.
ST640 questions from resellers
What is the minimum order on ST640 polos?
24 pieces, with no setup fees. Mix colors and sizes inside that 24 with the same logo.
ST640 or K110, which polo should I pick?
The ST640 is the breathability champion, the pick for anyone sweating outdoors. The K110 is the snag-resistant classic uniform look with UPF 30. Tell us who is wearing it and we will point you right.
Does it match the ST350 tees?
Yes, same PosiCharge color system, so a team can run tees and polos in one coordinated color. We can decorate both in one order.
Embroidery or print?
Either works; embroidery is the usual pick for polos. The mesh face embroiders cleanly with proper backing, which we handle in-house.
Will it fade?
That is what PosiCharge is for, it locks in the garment color through repeated washing. 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.
