【TOP-EX Instant Cooling Tech – No Water Needed】 Engineered for high-heat performance, this hat uses exclusive contact-cooling fabric in the sweatband, crown, and inner neck flap to deliver instant coolness—no water needed. The wide brim and full neck flap provide sun coverage while the breathable, sweat-wicking build keeps you dry. Ideal for hiking, fishing, beach walks, and long days outdoors. 【UPF 50+ Wide Brim & Neck Flap Protection】 With a 3.1" brim and 9.4" neck flap, this hat blocks 98% of UVA/UVB rays to protect your face, ears, and neck. Certified UPF 50+, it’s the ultimate sun defense for outdoor use—perfect for gardening, camping, boating, and travel. 【Rollable Brim That Holds Its Shape】 The soft-structured yet supportive brim is wind-ready and won’t flop. Our TOP-EX floating brim design adds structure and bounce-back recovery. Fold it flat, bend it inward, or roll it on the go—it’s packable, portable, and made for travel without losing its shape. 【Ventilated, Lightweight & Built for Movement】 Six mesh eyelets maximize airflow, and the moisture-wicking lining keeps you dry in heat. Lightweight yet durable, this hat stays put with an adjustable chin strap—great for outdoor work, hiking trails, or mowing the lawn. 【Sized for Every Head – Small or Oversized】 Unlike one-size-fits-all sun hats, TOP-EX offers 3 precision sizes for comfort and stability: M/L – 7 1/8–7 3/8 (22.4"–23.2"/57–59 cm) L/XL – 7 1/2–7 5/8 (23.6"–24.4"/60–62 cm) XL/XXL – 7 3/4–8 (24.8"–25.6"/63–65 cm). Each hat features an adjustable elastic drawcord at the back for fine-tuning fit. Whether your head is small or large, enjoy breathable, tailored sun protection built for real outdoor use. Stay cool, dry, and protected with the TOP-EX Cooling Sun Hat—engineered for real-world outdoor use. A 3.1" wide brim and 9.4" neck flap shield your face, ears, and neck with UPF 50+ sun protection, while our exclusive contact-cooling fabric delivers instant relief—no water needed. It’s built for hiking, fishing, gardening, camping, boating, and long summer days. Three packable options make it travel-ready: lay it flat (15"×7"×1"), fold from inside out (8.7"×6.7"×1"), or roll it down to the size of a large smartphone. The brim holds its shape, resists sagging, and recovers quickly—without being stiff or flimsy. Available in 3 sizes for a precise fit: M/L – 7 1/8–7 3/8 (22.4"–23.2" / 57–59 cm) L/XL – 7 1/2–7 5/8 (23.6"–24.4" / 60–62 cm) XL/XXL – 7 3/4–8 (24.8"–25.6" / 63–65 cm) Breathable, structured, and made for movement, this is the hat your summer needs.
