Sport-Tek Custom Decorated by OTIA

Performance-apparel workhorse — the catalog you spec for athletic teams, golf outings, race events, and any program where wearers are active outdoors.

Direct answer

Sport-Tek is SanMar's performance-apparel brand, built around moisture-wicking polyester tees, polos, fleece, and outerwear. The ST350 PosiCharge tee, ST650 PosiCharge RacerMesh polo, and ST850 Sport-Wick fleece pullover are the most-decorated SKUs. Customers choose Sport-Tek for athletic teams, golf outings, race events, outdoor staff uniforms, and any program where the wearer will be active outdoors. OTIA decorates Sport-Tek with DTF and embroidery (both work well on PosiCharge polyester).

Where Sport-Tek fits

Brand positioning & why customers choose Sport-Tek

Sport-Tek is the performance-apparel sibling brand to Port Authority — same SanMar catalog, same color-book consistency across years, same depth of distributor stock — but built around moisture-wicking polyester fabrics instead of cotton-blend uniform pieces. The PosiCharge construction (Sport-Tek's permanent color-locking dye technology) is the brand's signature: prints and logos stay vivid through repeated washing and high-heat dryer cycles in a way standard polyester does not.

Where Sport-Tek fits in the catalog hierarchy: mid-tier performance. The pricing band is comparable to Port Authority's mid-tier polos, the fits are athletic (slimmer through the body and shoulder than corporate-uniform brands), and the color stories lean toward sport (color-block options, athletic tones, race-team palettes). Buyers reach for Sport-Tek for athletic team programs, golf outings, 5K and race-event tees, summer outdoor-staff uniforms, and any application where active wearers and moisture management are part of the brief.

Polo · PosiCharge Micropique

Sport-Tek ST650 PosiCharge Micropique Polo

Pullover · Sport-Wick Fleece

Sport-Tek ST850 Sport-Wick Fleece Pullover

Mid-weight performance fleece with quarter-zip front. Moisture-wicking, layerable, the right call for fall and shoulder-season athletic team programs, coach apparel, and outdoor-staff cool-weather kits.

Youth Tee · PosiCharge

Sport-Tek YST350 Youth PosiCharge Competitor Tee

Youth-sized version of the ST350. Most youth-league and school-program tees ship as a mixed-size order combining adult and youth — the matched YST350 / ST350 SKU pair keeps color and fabric identical across age groups.

Polo · PosiCharge RacerMesh

Sport-Tek ST640 PosiCharge RacerMesh Polo

Lighter-weight performance polo with open-mesh construction for maximum airflow. The right pick for summer outdoor-staff uniforms (golf course, marina, outdoor events) where heat management matters more than the dressier ST650 micropique.

Decoration guidance

How we decorate Sport-Tek — methods, fit, and tradeoffs

DTF printing on Sport-Tek's PosiCharge polyester takes a different recipe than DTF on cotton — the print sits on a polyester face, which means dye-migration risk (color bleed-through from the garment into the print after high-heat curing) is real and has to be managed at production time. We use a low-melt adhesive and a specific cure profile on Sport-Tek to control migration; the result is a vivid, durable print that survives the dryer cycles that destroy cheaper polyester prints.

Embroidery works cleanly on Sport-Tek's polos (ST650 RacerMesh, ST640 micropique) and fleece (ST850 pullover, ST253 Sport-Wick fleece). The denser PosiCharge knit takes embroidered logos without puckering, and the moisture-wicking properties of the fabric are not compromised by a left-chest embroidered hit. For full-back logos, embroidery is heavier than DTF and may be felt against the skin — DTF is the right call when wearer comfort is a priority.

Sport-Tek's race-event tees and athletic team programs frequently combine front-chest DTF + back-yoke number / name embroidery — a multi-decoration build we quote as one all-in per-piece number against the same pricing module that runs every written OTIA quote. The per-piece price is flat across order quantity.

When to spec Sport-Tek

Two strongest fit-for-purpose use cases

Best for athletic team + race event program

Team sport programs, 5K race events, golf outings, athletic recruiting events

Sport-Tek's PosiCharge polyester construction is built for active wearers — the color-locked print survives repeated wash cycles, the moisture-wicking fabric performs in heat, and the athletic fit reads correctly on race participants and team members. The ST350 tee is the default 5K race shirt in our shop; the ST650 polo is the default golf-outing polo. Per-piece pricing is flat across order quantity from 25 pieces to 2,500.

Best for outdoor-staff summer uniform

Landscape, parking, recreation, marina, and outdoor-event staff uniforms

Outdoor-staff uniforms in summer demand fabrics that wick moisture and stay vivid after heavy wash-cycle abuse — exactly what Sport-Tek's PosiCharge construction delivers. The ST650 RacerMesh polo replaces a cotton Port Authority Silk Touch for outdoor crews who'd otherwise be drenched by 11 AM. Color books are stable across multi-year programs, which matters for uniform-program reorders.

FAQ

Sport-Tek questions we get most often

What's the cost band for Sport-Tek blanks?

Mid-tier blank cost, comparable to Port Authority's mid-tier polos. The ST350 performance tee sits at the entry of the brand's range; the ST650 / ST640 polos and ST850 fleece pullover sit mid-band. All-in decorated pricing is flat per piece at any quantity. See /pricing for the live calculator.

What decoration methods work best on Sport-Tek?

DTF printing with a polyester-tuned recipe — controls the dye-migration risk that's inherent to printing on polyester. Embroidery works cleanly on the polo and fleece lines. For race-event programs we frequently combine front-chest DTF plus back embroidery in one all-in per-piece price.

Do you keep Sport-Tek in stock or order to job?

Order to job from SanMar. Sport-Tek shares Port Authority's distribution backbone — deep stock in the SanMar Robbinsville NJ DC, next-day to Long Island on most SKUs. We don't pre-stock — color books and seasonal palettes shift and stock should be pulled fresh against the quote.

What are typical lead times on a Sport-Tek order?

7–10 business days from artwork approval for DTF prints on in-stock Sport-Tek blanks. Embroidery on polos and fleece tracks the same window. Race-event multi-decoration builds (front DTF + back embroidery) sometimes add 1–2 days because of the two-decoration workflow.

How wide is Sport-Tek's color availability?

Good on the anchor SKUs — ST350 carries 25+ colors including the athletic and high-visibility tones the brand is known for, ST650 RacerMesh runs 15–20, ST850 pullover ~10. Color books are reasonably stable year over year; SanMar refreshes seasonal Sport-Tek palettes more aggressively than Port Authority palettes.

What sizing range does Sport-Tek offer?

Adult XS through 4XL on the core ST350 / ST650 / ST850; XS through 6XL on selected SKUs. Ladies' fits (LST350, LST650, etc.) ship in the same color books as men's, important for mixed-fit athletic team programs. Youth sizing on selected race-event SKUs (YST350) matches adult color and fabric.

What happens if a Sport-Tek blank arrives defective or mis-sized?

If a blank arrives defective from SanMar we replace at no cost. If the wrong size was ordered against the approved spec, we re-quote a replacement at cost. Sport-Tek's athletic fit runs slimmer than cotton uniform polos — first-time buyers from Port Authority sometimes spec one size up to match the looser corporate-polo feel.

Can I mix Sport-Tek with other brands in one order?

Yes. Common mixed build: Sport-Tek ST650 polos for the outdoor field crew plus Port Authority K500 polos for the office staff, all on one quote with one logo setup. Or a Sport-Tek race-event tee plus a Champion S700 Powerblend hoodie for the post-event finisher kit. Mixed-brand orders don't change per-piece decoration pricing.
