The more breathable cousin of our other UPF shirts, the Florence Marine X Airtex L/S Shirt features a 20+ UPF rating, an airflow-friendly knit with 4-way stretch and an antimicrobial construction so you stay cool and fresh when you’re going for your personal best on the court or in the gym. Great for pickleball, surfing, climbing, hiking and staying comfortable while staying active on long hot days.

Long sleeve shirt
Very comfortable but seems to run large. I ordered large and just ordered medium for another one as I usually order large and seems slightly to big. Will see how medium works.

Recommended!
Fits pretty great, 5’9, 170lbs athletic build and the large fits a little loose but it’s nice and comfy! Breathable as well.

CRBN x Florence Marine X Airtex Long Sleeve Shirt
Way too big and I didn't care for the fabric.

Florence Marine X Airtex Long Sleeve Shirt
Great! Love this shirt. It's warm, but breathable. Love the simple design and the little red flag on the sleeve. Highly recommend. Would love to see a shirt like this in 100% cotton.
