Description

The Sport-Tek ST535 Sideline Polo is a light, performance ready polo built for active, outdoor wear and clean, professional branding. It is made from a 4.1 ounce 100% polyester with a UPF rating of 30 and odor resistant properties, so it blocks harmful UV rays and stays fresh through long days on the sideline, the course, or the field. The lightweight polyester stays moisture friendly, wrinkle resistant, and easy to care for, and the smooth surface gives decoration a clean area to work with. That protective, performance ready character makes the ST535 a strong choice for teams, coaching staffs, corporate programs, outdoor programs, and everyday active wear.

The construction is built for a clean, classic finish. A rib knit collar keeps the neckline neat and structured, and a 3 button placket with dyed to match buttons keeps the front clean and tonal. Back neck tape adds a clean, comfortable interior finish, the smooth polyester surface gives designs a clean area to work with, and a tear away removable label leaves a comfortable, brandable finish ready for your logo.
