What Fabric Technologies are Used in Sport-Tek: Sport-Wick, PosiCharge, Dri-Mesh
By: ShirtsBargain Posted on: Sep 15, 2025Sport-Tek is becoming an increasingly popular name in the U.S. wholesale performance apparel market thanks to its innovative blend of quality materials, serious functionality, and budget-friendly price points. With consumer demand for performance fabrics surging year-over-year, Statista reports that athletic and activewear, including performance shirts and polos, accounts for over $80 billion in U.S. sales as of 2025—brands like Sport-Tek are under the spotlight for teams, schools, businesses, and sports leagues nationwide.
But what really sets this brand apart is their forward-thinking fabric technologies that fuel performance on the field, in the gym, or at work; they are legitimately designed to address real performance challenges.
Let’s take a look at Sport-Tek’s fabric technologies behind some of their top-selling blank t-shirts and blank polo shirts in ShirtsBargain.
Key Fabric Technologies That Power Sport-Tek Apparel
Be it Sport-Tek polos, jerseys, jackets, active pants, or even their blank caps, Sport-Tek’s lineup features fabric innovations built for sweat-busting, color-holding, and all-day comfort. These are the core technologies that keep Sport-Tek ahead in the wholesale game.
PosiCharge—Lasting Color and Crisp Graphics
Posicharge technology locks in color and prevents logos from fading, making it Sport-Tek's flagship innovation. This electrostatic treatment bonds colorants at the molecular level during fabric production. The technology works across multiple fabric constructions and weight categories and is one big reason why their iconic ST350 Competitor t-shirt is a ShirtsBargain bestseller.
- Keeps garment color & custom logos looking new, wash after wash.
- Locks in dyes to prevent fading and color bleeding.
- Essential for teams and businesses using screen printing, DTF, or embroidery.
Apart from the customization of the Sport-Tek ST350 PosiCharge Tee, the Sport-Tek ST550 Competitor Polo, the ST340 RacerMesh t-shirt, the STC36 Mesh Back Cap, and a few other styles feature PosiCharge.
Sport-Wick - Peak Moisture-Management & Quick-Drying
Sport-Wick technology forms the foundation of Sport-Tek's performance fabric platform. This moisture-wicking system pulls sweat away from skin surfaces and disperses it across fabric exteriors for rapid evaporation. That is why Sport-Wick garments from Sport-Tek also dry up quickly. The technology works through specialized fiber construction and chemical treatments, all focused on enhancing performance for not just athletes but also casual wearers.
- Engineered to pull moisture away from the skin so wearers stay dry.
- Helps shirts dry quickly and reduces cling during workouts or outdoor events.
- Sport-Wick fabric features in Sport-Tek jackets, pullovers, and polos for enhanced moisture management.
The best example is the Sport-Wick ST650 Micropique Polo, which combines Sport-Wick and a silky smooth micropique texture, making it a go-to for golf clubs and coaches. As a matter of fact, Sport-Wick technology is the biggest reason why many Sport-Tek polos outclass traditional uniform shirts. It’s also one of the main differences between the ST650 and its preceding style, the ST550.
Sport-Wick fleece is also used in hoodies and pants to deliver sweat-free comfort, regardless of the environment.
Micropique and Polyester Knits—Comfort and Snag Resistance
Though technically not a fabric technology, Sport-Tek’s polyester knits and pique construction deserve praise for what they grant the brand’s offerings. Particularly, their polyester tricot micropique knit, like in the ST650, gives the polo its smooth, luxurious feel. This tricot knit also grants enhanced stretch, excellent snag resistance, and soft feel for all-day wear and resists pilling. They even named one of their Blank Track jackets after its tricot fabric construction.
- Popular for frontline employees or industries needing tidy, comfortable uniforms.
- Gives the garment a smooth, silky texture.
- Bonus features like snag-resistance, odor-resistance, shape retention, and breathability
Dry Zone and Dri-Mesh - Breathability in Every Layer
Sport-Tek’s Dri-Mesh fabric tech is a double polyester mesh construction that enhances breathability and comfort. The fabric will also wick moisture. Though the brand doesn’t offer a lot of Dri-Mesh styles, some of them, like the Sport-Tek K469 Dri-Mesh performance polo and the T474 Pro Polo, are great picks for hot climates and outdoor training. Dry Zone is similar but has a primarily polyester pique construction, offering moisture-wicking and odor resistance. Custom-ready baseball uniforms from Sport-Tek, like the T473 raglan t-shirt and the T478 colorblock crewneck t-shirt, feature Dry Zone technology.
- Dri-Mesh garments have a double-layer mesh to maximize airflow and release heat.
- Dry Zone garments wick moisture, resist odor, and are exceptionally breathable
- Both fabric technologies minimize sweat buildup.
- Dri-Mesh and Dry Zone apparel from Sport-Tek are generally lightweight and ideal for teams training or competing outdoors.
Versatile Embroidery and Decoration-Ready Fabrics
Sport-Tek’s polyester apparel is designed to deliver amazing results with embroidery, DTF, sublimation, and HTV processes. The color retention and durable weave help maintain the integrity of branded designs even after many wash cycles. We have customers who’ve been using the ST350 t-shirt for close to two years, without replacements. If you are new to Sport-Tek, you may want to check out our guide on Sport-Tek apparel wholesale.
- Schools often pick the ST350 or ST550 for spirit wear, as both styles deliver excellent results for complex team logos.
- Sport-Tek blank t-shirts and polos are great choices for events and promotions
- Sport-Tek sweatshirts are good choices for school-goers during the fall.
Buyer Tips: Investing in the Right Sport-Tek Apparel

- For outdoor leagues: Look for PosiCharge with UV protection (such as ST420 tee or ST740 polo).
- For heavy athletic use, choose Sport-Wick polos or pullovers for superior sweat control.
- For high-visibility branding: PosiCharge and smooth knits like micropique deliver the best result.
- For long-term value: Opt for snag-resistant styles.
