Fit Guide

Structured Athletic Fit

Designed to feel premium and intentional: fitted through the arms and chest, slightly tapered through the body, and extended in length so the shirt stays clean during training and daily wear.

Fit Philosophy

AAO tees are intended to fit athletic, not boxy. The goal is a clean silhouette that sits close through the upper body while still allowing movement.

Fitted sleeves, structured collar, slight taper, and extended length for training and daily wear.
