Fuzzballs get wearing once
Color: Black, Size: X-Large
Very smart to wear, but the quality is terrible so after one wash the collar start fraying and fuzzballs start forming. Very disappointing.

Comfy and well made
Hubby wears this when he golfs & weather is cool. Material is soft. Fits well. Looks more pricey than it is.
