Some call it Casual Friday, but we call it Tropical Friday with our new signature Hawaiian shirts.

Always fresh and cutting edge Half Sumo has created the ultimate short sleeve button up summer shirt. We've paired the original Half Sumo Irezumi designs with a new lightweight and athletic 100% polyester shirt that will not only keep you cool during these warm months, but its flexibility will make it a great companion for any fun activity this summer.

Have fun exploring the intricate design and get up close to new details like custom HS buttons and our signature Yurei patch on the left sleeve.

Fits a bit like a track shirt on the narrow side, we recommend sizing up for a looser fit, especially for larger sizes. Slim fit.
