Engineered by Experience is not a slogan; it is how TUOA(R) builds gear, and this tee carries the line. The body runs 4.3 oz./yd^2 of 60/40 combed ring-spun cotton and polyester knit at 32 singles, a finer yarn that gives the fabric a smooth hand and a light, soft feel. A self 3/8" shoulder to shoulder binding reinforces the shoulder line and helps the tee hold its shape, while a 3/4" neckband with 1x1 rib keeps the collar from stretching out. Side seams give it a cleaner drape than a tubular body, and the regular fit leaves room to move. Everyday wear, built the way we build everything else.
