Question 1

Is Sport-Tek ST350LS a performance t-shirt?

Accepted Answer

Yes. The ST350 and its variants including the long-sleeve ST350LS are all performancewear. The ST350LS in particular is designed for mobility and comfort with excellent moisture-wicking and durability.

Question 2

Can the ST350LS handle high-sweat situations better than cotton?

Accepted Answer

Yes. The Sport-Tek ST350LS performance tee is made of 100% polyester interlock, giving it moisture-wicking that’s superior to regular cotton t-shirts at an attractive price point.

Question 3

How does Posi-charge technology impact performance and comfort?

Accepted Answer

Sport-Tek’s PosiCharge does not impact performance and comfort. The fabric technology gets the best out of the 100% polyester interlock weave of the ST350LS and locks in the colors to deliver amazing results when customizing or branding the t-shirt. But because this is a performance t-shirt, its design itself is focused on remarkable comfort complemented by performance features.

Question 4

Is the Sport-Tek ST350LS t-shirt good for screen printing?

Accepted Answer

The Sport-Tek ST350LS can be screen printed. We have customers who have consecutively achieved great results printing on the ST350 and its variants. However, screen printing on polyester with plastisol may lead to dye migration. You can mitigate this to an extent with a blocker base ink. The PosiCharge technology also helps here by locking colors. We recommend simple designs when screen printing on the ST350LS.

Question 5

What do sports coaches say about outfitting teams with the ST350LS?

Accepted Answer

The ST350LS offers exceptional value, with a combination of performance features, durability, and excellent comfort. Though it falls under the performance apparel category, it’s not completely an end-to-end performance shirt. The key benefit is the value it offers to sports teams with tighter uniform budgets. For its price, the 350LS certainly delivers more than what’s expected. ShirtsBargain’s ST350 buyers include sports coaches and sports clubs.

Question 6

What is the difference between the ST350LS and PC380LS performance shirts?

Accepted Answer

The main difference is in customizability and applicability outdoors. The PC380LS t-shirt from Port & Company and the ST350LS from Sport-Tek are long sleeve performance t-shirts in the same weight category, designed for athletic environments. Both offer moisture-wicking with the PC380LS featuring DryZone wicking technology. The PC380LS also offers UPF 50 sun protection, which the ST350LS lacks. But the latter makes up for it with better durability and PosiCharge technology for color-locking. The polyester interlock fabric of the ST350LS also gives it more breathability than the 100% polyester PC380LS.

Question 7

Is the ST350LS better suited for high-impact sports or casual team runs?

Accepted Answer

We’d recommend it for casual team runs as high-impact sports require outfits specifically engineered for enhanced performance, superior comfort & mobility, and superior moisture management. Though the ST350LS is a performance t-shirt, it offers only a slight improvement over basic performance tees in the market. The low pricing is the main benefit. We would call it a lightweight athletic t-shirt that’s great for casual sports sessions, outdoor training, and workouts.

Question 8

Does the ST350LS feel like cotton?

Accepted Answer

No. The ST350 feels more like a jersey with a silky texture due to being 100% polyester.

Question 9

How does the ST350LS fit?

Accepted Answer

According to many of our customers, the ST350 runs a little big. If you order a size smaller, it will give you a fitted, not-too-tight athletic fit.

Question 10

Is ST350LS available with short sleeves?

Accepted Answer

Yes. The short sleeve variant is ST350 which comes in 35 colors. A youth-size variant is also available in ShirtsBargain with the style code YST350.

Question 11

What is the fabric and weight of the ST350LS?

Accepted Answer

It’s a 3.8 oz, 100% polyester long-sleeve tee featuring PosiCharge technology to lock in color and resist fading.

Question 12

Is the fit unisex and what sizes are available?

Accepted Answer

Yes. It’s a unisex style offered in XS, S, M, L, XL, 2XL, 3XL, and 4XL.

Question 13

What does the shirt feel like and how breathable is it?

Accepted Answer

It has a soft, silky feel and is lightweight, highly breathable, and moisture-wicking. In general, 100% polyester is less breathable than 100% cotton.

Question 14

Is this shirt good for sublimation and will colors stay vibrant?

Accepted Answer

Yes—it's great for sublimation, and PosiCharge helps colors remain bright through many washes. Because sublimation uses high heat, sample-test by color and consult your decorator.

Question 15

Which decoration methods are recommended?

Accepted Answer

Best for sublimation, screen printing, and heat transfer; also suitable for DTF and vinyl. While some crafters DTG on polyester, ShirtsBargain currently offers DTG only on 100% cotton t-shirts.

Question 16

Any tips for heat-applied decoration on this tee?

Accepted Answer

For HTV on 100% polyester, use lower temperatures with longer press times and test a small patch first. To avoid press marks, keep temps/time appropriate and the heat-press platen clean; for sublimation, sample-test by color before production.

Question 17

What sleeve and tag details should I know?

Accepted Answer

It features set-in sleeves and a removable tag (tag-free label) for comfort and easy relabeling.

Question 18

Does it wick moisture and work for outdoor activities like fishing?

Accepted Answer

Yes. The fabric is moisture-wicking, lightweight, and breathable, making it a solid pick for activities like fishing and long days outdoors.

Question 19

How does the ST350LS compare to the ST350 short-sleeve tee?

Accepted Answer

Both use the same 3.8 oz, 100% polyester interlock with PosiCharge and share moisture-wicking performance; the ST350LS has long sleeves, while the ST350 is short-sleeve.

Question 20

How does the ST350LS compare to the ST550 polo?

Accepted Answer

Both are 3.8 oz, 100% polyester with PosiCharge; the ST550 adds a flat knit collar and 3-button placket for a polo look, while the ST350LS is a crewneck performance long sleeve suited to tee-style projects.
