The classic T3 Hat is built with the Tilley Hat fabric that started it all - cotton duck. This rain-repellent and mildew-resistant, preshrunk 10-oz., 100% cotton fabric is derived from an incredibly durable sailcloth that is still used in boating today. The T3 is designed with a medium brim that snaps up on both sides, a dark underbrim for glare protection, a secret pocket for storing small personal items, and ventilation grommets to keep you cool in warmer weather. This feature-rich hat offers excellent sun protection with a UPF 50+ rating, is machine-washable, won't shrink, ties on in the wind, and it floats, too! Each hat is handsewn using super-strong thread, and all seams are lock-stitched so they won't unravel. Tilley Hats are guaranteed for life not to wear out and are insured against loss. 2-3/4" brim in front and back; 2-3/8" brim on the sides. Weighs 5.4 oz. Imported.
