Performance Long Sleeve Shirt — "First Do No Harm / Primum Non Nocere" Minimalist Athletic Tee
This lightweight long sleeve blends performance and quiet confidence. Breathable, quick-dry polyester keeps skin dry during runs, hikes, or long days under the sun while UPF 30+ offers built-in protection when you push farther. The athletic cut moves with you without cling; the soft, low-weight fabric sits cool against skin. A subtle, centered Latin chest graphic gives the piece an understated, travel-ready look — easy to layer, easy to wear when you want function that doesn’t shout. Wear it for early morning training, late-afternoon paddles, or when you need a reliable layer for weekend adventures.
