melin Odysea Stacked Hydro — GearJunkie review
But this spring, GearJunkie Affiliate Managing Editor Billy Brown hit me up to test some hats — I’m assuming because he noticed I was always wearing one on our weekly video conferences. It was a brand called melin. He told me to hop on the site and pick a few out.
Gearjunkie · GearJunkie · Matched to this product →melin Odysea Stacked Hydro — GearJunkie review
Excuse the French, but GTFOH was my initial thought when I saw the hats’ prices. They wanted dang near $100 for a baseball hat. That was absurd. But I had a job to do, and told Billy what I wanted. I planned on ripping melin a new one.
