Varsity / Cruise Jackets
Cruise jacket sizing runs true to standard letterman fits. Check the size chart photo in each jacket listing for exact measurements.
How to measure: lay a shirt that fits you well on a flat surface. Measure across the chest from armpit to armpit (chest width) and from the highest point of the shoulder to the bottom hem (length), then compare to the chart.

Crossing the Equator for the first time turns a sailor from a “Pollywog” into a trusty “Shellback” — one of the oldest and most enduring traditions in naval service.
This long sleeve shirt carries that legacy wherever you go. Printed to order.
