100% polyester cooling performance fabric. Moisture-wicking. UPF 30+ sun protection. Sizes S through 4XL. Multiple colors.
A4 built a reputation in the athletic apparel market by engineering performance fabrics that deliver real functional benefits at wholesale prices, and the N3142 Cooling Performance Tee is a solid example of that approach. The 100% polyester construction wicks moisture away from the body during active use, the UPF 30+ rating provides meaningful sun protection for outdoor programs, and the odor resistant treatment keeps the garment fresher through extended wear. For athletic programs, outdoor staff, summer camps, and any application where the shirt gets worn hard in warm conditions, the N3142 covers all the functional bases.
The flat seam construction reduces chafing during high-output activity, which matters for programs where athletes wear the shirt for extended periods. The 100% polyester construction makes the N3142 fully compatible with sublimation printing for programs that want vibrant, all-over color decoration — a meaningful advantage over cotton or cotton/poly blends for sublimation decorators. Heat transfer and screen printing with poly-appropriate inks also work well on the smooth polyester surface.
For a women's version in the same A4 cooling performance lineup, check the A4 NW3142 Ladies Cooling Performance Tee. For a comparable moisture-wicking performance tee from another brand, the Sport-Tek ST350 PosiCharge Competitor Tee is one of the most widely ordered performance blanks in the wholesale market. For an athletic tee with a cotton-feel fabric, the Sport-Tek ST410 PosiCharge Tri-Blend Wicking Draft Tee offers a softer hand feel with moisture management.
What does UPF 30+ mean?
UPF stands for Ultraviolet Protection Factor. A UPF 30+ rating means the fabric blocks at least 97% of UV radiation from reaching the skin. For programs that spend extended time outdoors — summer camps, outdoor sports, field staff — a UPF-rated garment provides meaningful sun protection beyond what an unrated tee offers.
Is the N3142 good for sublimation printing?
Yes. The 100% polyester construction is fully compatible with sublimation printing, which requires high polyester content for vibrant, durable color transfer. The N3142 is one of the better wholesale blanks for sublimation programs that need an athletic tee rather than a standard sublimation blank.
