Dionic utilizes a Polartec fabric for their latest rendition of their fan-favorite headwear piece. Check out the Glacial OctoSlugger 59Fifty Fitted Hat. This one’s built for wintertime thanks to the blue Polartec fleece fabric used for the dome and uppervisor. The OctoSlugger appears in a sky blue embroidery for the front design of this hat. They then placed the Polartec woven label between the left front panel and the uppervisor. The undervisor is made of satin fabric in sky blue. On the left panel is the New Era Flag, and at the back is the Dionic logo. Available now at the Dionic online shop.
