Sport-Tek LST350 Ladies Competitor Tee: Women's Performance DTF Printing Guide

Here's a scenario every DTF printer knows: a customer orders 30 unisex performance tees for a co-ed rec league and half the women complain the shirts are too boxy and long. You lose the reorder.

The Sport-Tek LST350 Ladies PosiCharge Competitor Tee solves this. It's the women's-cut version of our recommended ST350 Competitor Tee — same 3.8 oz polyester interlock, same PosiCharge dye-migration protection, same color palette — but with a gently contoured silhouette designed specifically for women's bodies.

Offering a ladies-cut option alongside the unisex ST350 shows your customers you care about fit, and it's the kind of detail that turns one-time buyers into repeat accounts.


Why the LST350 for Women's Performance Orders

Contoured Feminine Fit

The most important difference between the LST350 and the unisex ST350: the LST350 has a slightly tapered waist and shorter body length designed for women's proportions. It doesn't swim on smaller frames, and it doesn't bunch at the hips. Women actually want to wear this shirt — not just at the event, but afterward.

This matters for your business because shirts people wear after the event = free advertising for your customer = repeat orders for you.

Same PosiCharge Protection

The LST350 uses the exact same PosiCharge technology as the men's/unisex ST350. That means the same dye migration protection when pressing DTF transfers on dark and bright colors. Everything we covered about PosiCharge in our ST350 guide applies here — color locked into the yarn at the fiber level, less garment dye bleeding through white transfers, and better logo longevity through repeated washing.

25+ Colors — Perfect Color Match with ST350

The LST350 comes in 25+ colors that align with the ST350 palette:

Standard Colors: Black, White, Silver, Grey Concrete, Iron Grey, True Navy, True Royal, Carolina Blue, Atomic Blue, Tropic Blue, Kelly Green, Forest Green, True Red, Deep Red, Cardinal, Maroon, Deep Orange, Gold, Purple Neon/High-Visibility: Lime Shock, Neon Orange, Neon Pink, Neon Yellow Heather Options: Grey Concrete Heather, Iron Grey Heather

This means you can fill a co-ed team order with matching colors in both unisex (ST350) and ladies (LST350) cuts. Everyone gets the same team color, everyone gets a fit they're comfortable in.

Sizes XS Through 4XL

The LST350 goes up to 4XL, providing inclusive sizing for women's performance wear. This is important — women's athletic apparel often tops out at XL or 2XL, which leaves many customers without options. Being able to offer the same shirt through 4XL is a genuine competitive advantage.


LST350 Size Chart: Complete Measurements

The LST350 follows a women's contoured cut — narrower through the chest and shorter in body length compared to the unisex ST350 at equivalent letter sizes.

How Ladies Sizing Compares to Unisex

Ladies SizeLadies WidthUnisex EquivalentUnisex Width
LST350 S17½"ST350 XS18"
LST350 M18½"ST350 XS–S18"–20"
LST350 L20"ST350 S20"
LST350 XL21½"ST350 S–M20"–22"
The LST350 runs about 1–2 sizes smaller in width than the unisex ST350 at the same letter size. A woman who wears a Medium in unisex should try a Medium or Large in the LST350, depending on how fitted she wants it.
Order management tip: When quoting co-ed teams, always ask if women on the team want unisex or ladies-cut shirts. Include both options on your order form. This prevents complaints and returns, and it positions you as a printer who pays attention to detail.

DTF Printing on the LST350: Settings & Tips

Same fabric, same weight, same PosiCharge — same DTF settings as the ST350.

### Ladies-Specific DTF Tips
  1. Scale your designs for the contoured cut. A 12"-wide chest design that looks perfect on a unisex Large will extend too close to the side seams on a ladies Large (20" width vs. 24" width). Scale women's chest prints to roughly 80% of your unisex design width as a starting point.
  1. Placement differs from unisex. The LST350's shorter body length means your standard placement measurements from the collar will put the design lower relative to the overall shirt. Drop your starting point by about ½" to ¾" compared to unisex placement. Check our Shirt Placement Guide for details.
  1. Consider the contour. Women's shirts are tapered at the waist, which means wide, rectangular designs can look slightly distorted when worn. Designs that are taller than they are wide tend to look better on contoured-cut shirts.
  1. Smaller pressing pillow. The narrower body of the LST350 (especially XS–M sizes) needs a smaller pressing pillow than you'd use for unisex shirts. Using a too-large pillow will stretch the shirt on the press and can cause uneven adhesion.
  1. Same PosiCharge benefit. Dark color dye migration protection works the same as the unisex version. You still get that extra margin on reds, navies, and greens.

  • Higher perceived value — customers notice when you offer options instead of one-size-fits-all
  • Better word of mouth — women who love how their team shirt fits tell other team managers
  • Same DTF workflow — no additional setup, no different press settings, just a different blank from the same supplier

Common Questions

How does the LST350 fit compared to a standard women's tee? The LST350 has a relaxed, gently contoured fit — not skin-tight like activewear, but not boxy like a unisex tee. Think "flattering without being restrictive." Most women find it comfortable for both athletic activity and casual wear. Can I order ladies and unisex in the same color and they'll match? Yes. The LST350 and ST350 use the same dye lots and color standards. True Royal in ladies matches True Royal in unisex. This is one of the biggest advantages of staying within the Competitor family. Is there a ladies long sleeve version? Sport-Tek offers the LST350LS (Ladies Long Sleeve PosiCharge Competitor Tee) in select colors for women who want long-sleeve options. Is the LST350 available at S&S Activewear? No. Sport-Tek is a SanMar brand. Purchase through SanMar or JiffyShirts. Does the LST350 work for sublimation too? Yes. The 100% polyester construction works for both DTF transfers and sublimation. For sublimation, use white or very light colors.
