How does the ST550 perform compared to other performance polos, like the Port Authority K540?

The Port Authority K540 is an upgrade to the iconic K500 Silk Touch Polo. The K540 is a performance polo at a slightly higher per-piece pricing compared to the ST550, but quite close in performance. The ST550 and K540 are made of 100% polyester double knit. Both styles feature PosiCharge fabric technology, to hold colors better. The ST550 is a bit lighter than the K540 but it isn’t noticeable. Both styles wick moisture, offer exceptional comfort, and are very durable. Overall, we would say the K540 scores a little higher. But at a lower per-unit price, the ST550 is a solid option with performance that comes really close.

Can the Sport-Tek ST550 retain its shape after multiple washes?

Yes. The performance polo shirt is made with 100% polyester interlock. Polyester gives the polo superior durability and shape retention. With PosiCharge technology, the fabric also locks in colors when customizing, offering durable prints as well.

Where to buy the Sport-Tek ST550 in bulk for team or corporate uniforms?

You can buy Sport-Tek polo shirts in bulk from any wholesale distributor. ShirtsBargain is one source that offers the best value on bulk purchases of popular blank apparel styles from brands like Sport-Tek, Port Authority, CornerStone, Hanes, Mercer + Mettle, and more with the lowest per-unit prices in the wholesale market. The ST550 polo shirt in ShirtsBargain starts at $5.95 per piece, which may vary but continues to remain the lowest year-round. Make sure to log in to ShirtsBargain to view our low store-pricing on products.

Is the ST550 Competitor polo appropriate for casual wear, or is it better suited for promotional use?

The Sport-Tek ST550 is engineered to be a budget-friendly, performance uniform polo shirt. Its customizability and low-pricing also make it a solid choice for promotions and reselling. The ST550 is also preferred by golfers and golf clubs.

What types of customization works on Sport-Tek ST550 performance polo?

The 100% polyester performance polo is excellent for sublimation, HTV, and DTF. It can also be screen printed by experts with simple designs as the PosiCharge bypasses dye migration to an extent. The polyester interlock weave provides a great space for machine embroidery as well. We don’t recommend using the ST550 for DTG projects as the ink may not penetrate the interlock or may result in faded or cracked prints.

What performance features does the Sport-Tek ST550 have for active use in warm weather?

The ST550 is lightweight at 3.8 oz and is made of a polyester interlock fabric that ensures breathability. Though the polo isn’t as breathable as a 100% cotton polo, it more than meets your expectations of breathability from a polyester polo. The fit, breathability, durability, moisture management, and comfort of the lightweight ST550 combined make it a great choice for active use in warm weather. As a matter of fact, some of our customers in the corporate and hospitality sectors buy ST550s to outfit their teams during warmer months.

How can I choose the right color of Sport-Tek ST550 for branding?

Compare your brand’s color palette to the 17 color choices of the ST550 to find a close or exact match. You should consider the core colors in your brand’s logos, team colors, websites, and other promotional materials. Then it comes down to choosing an ST550 color that complements the core colors of your brand or matches them exactly. Complementary colors can still fit into the color palette after customizing the polo with your brand’s logo. There’s a lot of ways to go about this. Feel free to talk to our customer support team for guidance.

Is the Sport-Tek ST550 worth it if you’re looking for a high-end, luxury polo shirt?

No. The ST550 is engineered to be a value-priced performance polo that suits executive uniform programs, team outfitting, events, and promotions. If you wish to buy luxury polo shirts in bulk, check out ShirtsBargain’s Tommy Bahama polos or polo shirts from TravisMathew. These brands offer luxe polo shirts made with the finest materials in the world and designed to offer absolute comfort.

Is the Sport-Tek ST550 really worth the price compared to other polos?

Absolutely. Sport-Tek specializes in offering customizable athletic and performance apparel at budget-friendly prices. At this price range, Sport-Tek is also among the top brands in America offering good-quality polo shirts. Certain polo styles from Sport-Tek rival even iconic polos from leading brands that charge significantly higher prices in terms of features, color options, and durability.

Does the ST550 polo shirt from Sport-Tek offer sun protection?

No. The ST550 is praised for durability, color-locking, moisture management, and smooth texture. For sun protection, you need to get polo shirts with a high UPF rating. If you prefer Sport-Tek polos, we recommend the Sport-Tek ST740 UV Micropique Polo, which has a UPF 50 rating for excellent sun protection. If you need PosiCharge polo shirts with UV protection, check out Sport-Tek ST520 Posi-UV ™ Pro Polo or the ST520LS long sleeve variant.

What is the fabric and weight of the Sport‑Tek ST550 polo?

It’s made from 3.8‑ounce, 100% polyester interlock with PosiCharge technology.

Does this polo wick moisture and help colors last?

Yes. It’s moisture‑wicking, and PosiCharge technology helps lock in color to prevent logos from fading.

What collar and placket details does it have?

It features a flat knit collar and a 3‑button placket with dyed‑to‑match buttons, plus set‑in, open hem sleeves.

Does the ST550 have a tag, and how is the neck finished?

It has a removable tag for comfort and relabeling, and a taped neck.

Is the material lightweight or sheer?

The fabric is lightweight and breathable, with a slightly sheer hand noted by customers.

What sizes are available for the ST550?

Sizes range from XS to 4XL (XS, S, M, L, XL, 2XL, 3XL, 4XL).

Can I customize this polo, and which decoration methods are recommended?

As a 100% polyester performance polo with PosiCharge, it’s optimal for sublimation, HTV, and DTF transfers. Due to the nature of performance polyester, special care must be taken throughout the printing process.

Do you offer screen printing or DTG on this polo?

We do not currently offer polos with a screen‑printed logo. We offer DTF (direct‑to‑film) printing that you can apply to this polo, and we currently offer DTG only on 100% cotton t‑shirts.

How does the ST550 compare to the LST550 ladies version?

Both use 3.8‑oz, 100% polyester with PosiCharge and share similar features; the ST550 is the men’s fit with a 3‑button placket, while the LST550 is the ladies fit with an elongated 2‑button placket and women’s sizing.

How does the ST550 compare to the ST350 PosiCharge Competitor Tee?

Both are 3.8‑oz, 100% polyester with PosiCharge and moisture‑wicking performance; the ST550 is a polo with a flat knit collar and 3‑button placket, while the ST350 is a crewneck tee. Both are suitable for sublimation and DTF transfers.
