• Self-fabric collar — clean, modern neckline
• Heat-seal label — tagless comfort
• Side-seamed construction — contoured athletic fit

Why Choose Performance Over Cotton for Long Sleeves?

• Moisture management — cotton absorbs sweat and stays wet; polyester wicks it away and dries in minutes
• Wrinkle-free — looks crisp straight out of the bag, no ironing needed
• Odour resistance — doesn't hold odour like cotton after a long day
• Sun protection — full arm coverage plus UV-blocking polyester for outdoor crews
• Lighter weight — at 3.8 oz, it breathes better than a cotton long sleeve for active work
• Colour retention — polyester resists fading from washing and sun exposure

Best Print Methods for the S350LS

• Screen Printing — excellent results with athletic-grade polyester inks. Bold, durable prints for team logos and event graphics.
• DTF (Direct-to-Film) — outstanding on polyester. Vibrant full-colour transfers with excellent adhesion and durability.
• Heat Transfer / Vinyl — the smooth polyester surface provides superior adhesion. Ideal for names, numbers, and team customization.
• Embroidery — works well for small left-chest logos. Use lightweight backing for best results on this light fabric.
• Sublimation — 100% polyester means sublimation is an option for all-over prints on white/light colours.
