The FeatherFlage shirt is about a 3.0oz cotton - super light.
These all feature a mesh-lined vented back like a fishing shirt, long tails, broad shoulders, and twin breast button flap pockets. Get some and don't look back.
Sizing Tip - These are a full cut, with long tails (37"+ on a 4XL - So it's a TALL Cut). They are made to fit a guy comfortably according to our expectations on our size chart. THANKS!
