Common questions from gyms and studios

How fast can you turn around trainer shirts for a new hire?

Reorders of an existing design (art already on file) ship in 4 business days standard, 2 days rush. Since your art and logo are saved forever, adding one more polo is a two-line email.

Can you do names on the back of trainer polos?

Yes. Names, titles, or credentials on the back with embroidery. $6/piece extra per name — you send us the list, we handle the rest.

What's the best fabric for a hot Bikram or spin studio?

Sport-Tek ST350 or ST650 — 100% polyester with PosiCharge (colors don't bleed with sweat). Slightly upcharged vs. cotton but essential for cardio-heavy studios.
