Cut too small - Shrinkage!
Size: 3X-Large, Color: Chill
This Costa Del Mar shirt is cut way too small and then shrinks from there. Could not wear after one wash. I’m 6’4” @ 215 and normally wear XL or sometimes XXL. This XXL was really too small from the jump and then shrunk down so much I can’t even wear it. If you just have to get it, I’d order 2 sizes up. Not the quality I’m accustomed to in Costa products.

Perfect Fit!
Size: Medium, Color: Dark Heather, Size: Medium, Color: Dark Heather
My daughter got the Costa T-shirt for her boyfriend, and he absolutely loves it! The fabric is super soft, lightweight, and breathable—perfect for everyday wear or a day out on the water. The fit is just right, and the design looks even better in person. Great quality and a solid pick for any Costa fan!
