Our t-shirts are a regular fit and are true to size. Black and navy colors are made from 100% cotton. Sport Grey color is a 90%/10% cotton/polyester blend and Dark Heather color is a 50%/50% cotton/polyester blend.

Our t-shirts feature a preshrunk jersey knit, ensuring a comfortable and reliable fit. The design includes a seamless double-needle 7/8" collar, along with taped neck and shoulders, providing enhanced durability.

The tear-away label adds convenience, and the double-needle sleeve and bottom hems contribute to a polished finish. Moreover, the quarter-turned construction eliminates the center crease, further enhancing the shirt's overall appeal and wearability.

A Length

Place the end of the tape beside the collar at the top of the tee (Highest Point Shoulder). Pull the tape measure to the bottom of the shirt.

B Chest

Measure yourself around the fullest part of your chest. Keep the tape measure horizontal.

C Sleeve length

Place the end of the tape at the center back of the collar, then pull the tape measure along the top seam of the sleeve. When you get to the shoulder hold the tape in place at the shoulder and continue to pull down the sleeve until you reach the hem of the sleeve.
