Great purchase
Size: Large, Color: Blue Shark-white
Shirt was the perfect gift for my 21 year old son. The small pattern was perfect and he said that made the shirt cool. The material is comfortable and light enough for warm weather without feeling cheap. Shirt is versatile with the ability to dress up or down.
