Pattern is the Regan- Aviator hat by Julie Taylor (Ravelry Link) 
 Made from Miss Babs Yowza in Moss & Starling.
Gauge on a size 7 was 5 st/in. and 7.25 rows/in.
Rockwell is 6 months old, but I made the 1 year size in the pattern to give him room to grow.
Special thanks to his mamma, Katie for the adorable Carhartt shots.
