It’s a hit!
Color: Brown Grey Camo, Size: Large
I picked on of these up after seeing it online. I have multiple Maelreg items and all are great quality. They are my go to golf and casual clothing brand. Super comfortable, soft, light weight, and perfect fit. Olive on the east coast and this color is all the rage in the area. These are some of the best value 1/4 zips out there.
