Sport-Tek PosiCharge RacerMesh Long Sleeve Tee

The Sport-Tek® PosiCharge® RacerMesh® Long Sleeve Tee ST340LS is a lightweight performance shirt built for exceptional breathability, moisture management, and lasting brand visibility. Made from 3.8 oz. lightweight 100% polyester flat back mesh, its ultra-fine RacerMesh® construction delivers subtle texture and excellent airflow without the bulk of a traditional jersey. PosiCharge® technology helps preserve color and maintain a professional appearance over time, while the smooth, fine mesh surface gives your company logo, team name, slogan, or brand message a sharp, athletic look.

This performance tee offers versatile options for customized branding. Screen printing produces bold, long-lasting graphics and is a cost-effective choice for larger team, school, company, and event orders. Full-Color DTF printing handles detailed artwork, gradients, and unlimited colors, making it ideal for intricate logos and vibrant graphics. Embroidery provides a premium, dimensional stitched appearance for organizations looking for a more elevated and professional presentation.

Designed for active use, the ST340LS combines moisture-wicking performance with ultra-fine flat back RacerMesh® for outstanding breathability and comfort. Set-in sleeves provide a clean, structured silhouette, while the lightweight polyester construction is durable enough for repeated wear. A tag-free label eliminates the distraction of a traditional neck tag for added comfort during long days, practices, events, or work shifts.

Ideal for sports teams, school athletics, corporate events, employee apparel, outdoor crews, promotional programs, and branded merchandise, this long sleeve performance tee delivers comfort without sacrificing visibility. Its breathable construction, moisture-wicking performance, and color-preserving technology make it a smart investment for keeping your branding bold, sharp, and professional through repeated use.
