Premium polyester or technical fabric (nylon ripstop, polyamide/elastane blend) with quick-dry properties and low water absorption for minimal retention and maximum comfort in wet conditions.

Water-repellent finish (DWR – Durable Water Repellent): optional but recommended to prevent water absorption and keep the cap lightweight and breathable even when wet.

UV protection: UPF 50+ blocking over 98% of harmful UV rays for maximum sun safety during long exposure sessions.

Ventilation / breathability: side panels or mesh eyelets designed to promote airflow, reduce heat buildup, and speed up drying.

Inner sweatband: an antimicrobial, anti-odor moisture wicking band that efficiently absorbs sweat and stays comfortable after immersion.
