Sealskinz Black Thursford Ultra Lightweight Foldable Running Cap

Our lightest-weight running cap, designed for runners who need maximum ventilation, minimal weight, and zero distraction. Built for fast-paced sessions and warm-weather runs, this cap delivers breathable comfort with an ultra-light, barely-there feel. A streamlined, foldable design makes it easy to stash when not in use, while Solarsealz™ UV protection ensures unwavering protection and efficient performance from start to finish. Technology Engineered for high-output performance, Thursford uses an ultra-light, unlined construction to reduce weight and enhance breathability. Perforated side panels allow heat to escape quickly, promoting airflow and helping regulate temperature during intense activity. Quick-drying fabric efficiently manages moisture, while built-in Solarsealz™ UV protection adds confidence for long days outdoors. A shorter, foldable peak improves forward visibility and makes the cap easy to pack away, while an elasticated rear drawcord provides a secure, adjustable fit that stays comfortable on the move. Activities Designed for runners who train hard in warm and variable conditions, Thursford is ideal for daily training runs, tempo efforts, and race-day use. Its lightweight, breathable construction and added Solarsealz™ UV protection make it particularly well-suited to hot-weather running and high-intensity sessions, where ventilation and moisture management are essential. Whether you’re pushing the pace or heading out for long miles under the sun, Thursford helps you stay cool, focused, and comfortable. Materials and Construction Sealskinz accessories are subject to intensive testing before coming to market.
