Sport-Tek Apparel

Sport-Tek is a dominant brand in wholesale athletic apparel, carried by more decorators, teams, and uniform programs than any comparable performance line. At Bulkthreads.com, the full Sport-Tek catalog ships fast with automatic bulk discounts — no codes, no minimums.

The ST350 PosiCharge Competitor Tee is one of most decorated blank performance tees in the wholesale market. PosiCharge technology locks in color during printing and washing, which explains why so many screen printers and decorators default to the ST350 for their athletic lines. It's available in basic, traditional, and extended colorways, plus a long-sleeve version (ST350LS) for year-round use. Women's and youth are covered too: the LST350 Ladies Competitor Tee and YST350 Youth Competitor Tee. For big and tall programs, the TST350 Tall Competitor Tee and TST350LS Tall Long Sleeve fill a gap most competitors leave open.

The ST550 PosiCharge Competitor Polo covers the value end of Sport-Tek's polo range — moisture-wicking, color-locking, and available in the same broad color palette as the ST350. For clients that want a finer fabric hand, the ST650 Micropique Sport-Wick Polo offers a tighter knit with a more refined appearance, one that works for golf, hospitality, and corporate uniforming. The ST640 PosiCharge RacerMesh Polo is knit with an open-mesh construction for maximum breathability indoors and out. Women's versions are available for all three: LST550, LST650, and LST640. The TST650 Tall Micropique Polo rounds out the polo lineup for extended sizing programs.

The ST420 Posi-UV Pro Tee is Sport-Tek's purpose-built sun-protection tee — UPF 50+ rated, moisture-wicking, and built for outdoor programs, summer camps, and water-adjacent activities. It's available in short and long sleeve (ST420LS), with a youth version (YST420) and a ladies scoop neck (LST420). The ST520 Posi-UV Pro Polo brings UPF 50+ protection into a polo construction for golf and outdoor staff programs, with a women's version (LST520) available as well.

The ST356 PosiCharge Competitor Tank is the sleeveless counterpart to the ST350 — same PosiCharge fabric, same color-locking for decoration. The LST356 Ladies Racerback Tank and LST402 Tri-Blend Wicking Tank cover the women's segment. For programs that want a cotton-feel hand with performance properties, the ST450 Competitor Cotton Touch Tee bridges the gap — polyester construction that mimics the feel of a ring-spun cotton tee.

Sport-Tek's fleece lineup spans from athletic to premium. The F281 Heavyweight Hoodie and F280 Heavyweight Crewneck are built for programs that need substantial weight and structure — heavier than standard blanks, with a surface that holds print particularly well. The F282 Heavyweight Full-Zip completes the set. The F244 Sport-Wick Fleece Hoodie is the performance alternative — moisture-wicking polyester fleece for athletic programs that want warmth without cotton. For stretch and versatility, the ST850 Sport-Wick Stretch 1/2-Zip is a standout — four-way stretch fabric that works for both athletic and smart-casual applications, with a women's version (LST850) and tall sizing (TST850) available.
