Thomas G.wrote a review of Sunday Afternoons River Guide Hat - Men's on August 25, 2016
Familiarity: I've used it once or twice and have initial impressions
Fit: True to size
This hat will protect you all day and is a well built product that should last a very long time.
It's my third Sunday Afternoons hat and the biggest by far. I use all three depending on the amount of sun and time I'll be in it.
