Built in collaboration with Sig Zane Designs, the Florence x Sig Zane Koa Airtex Hooded Long Sleeve Shirt is engineered with lightweight, breathable Airtex fabric for maximum ventilation and quick-dry performance. Featuring Sig's original Koa artwork, it delivers UPF protection with a streamlined fit designed for long days in and around the water. Combining modern function with cultural heritage, this hooded shirt embodies the shared vision of FLORENCE and Sig Zane Designs.
This print, Ka-Maka-Lau-Koa, illustrates a cycle within the Hawaiian forest from the young sapling to the mature koa tree. At one hundred twenty-five years old, the koa tree would be large enough to be carved into a canoe. To hull a canoe, a thirty-five to forty-five foot length along with a diameter of forty-eight inches or more is required. Lashed and tied together our canoes allowed the culture to migrate and flourish.
