The Tilley LTM3 Airflo Hat is practically identical to the Tilley T5MO Organic Cotton Airflo Hat except for a few small differences. The LTM3 doesn't use organic cotton, and it allows you to snap the sides of the brim up, and the brim is a slightly different shape. Other than these things we didn't notice any differences. Both of them have decent protection, good style, and are the most durable hats we tested.
We recommend using these hats for traveling because their amazing durability, the secret stash pocket in the top of the hat, and their small brim allows you to navigate the crowds while staying protected at the same time.
