The versatile Totally Tubular is a must-have for any kid that loves to be and stay outside! Lightweight and pocket-packable, the Totally Tubular are comprised of our proprietary technical fabric, Comfort Shell™, which sets it apart from all other multi-functional headwear. It is moisture-wicking and form-fitting with a 4-way stretch fit, anti-microbial properties, and a soft, brushed interior - designed with just one small seam up the back. Solid color options have a bold color on the outside and inside, while the printed options are bright and fun on the outside and white on the inside.
