The Gill Hydrophobe Trousers are designed to work seamlessly with the Hydrophobe Top, delivering lightweight thermal protection, flexibility and all-day comfort on the water. Worn as a base layer under wetsuits or drysuits, they help regulate body temperature and keep you comfortable during long sessions in changing conditions.

Constructed from a soft, fast-drying polypropylene blend with 4-way stretch, these thermal leggings move naturally with the body while maintaining a close, supportive fit. Built-in thermal insulation and UPF 50+ sun protection make them suitable for both cold-water performance and brighter conditions.

Flatlocked seams minimise irritation during active use, while the adjustable waist provides a secure, custom fit when layering. Lightweight, breathable and quick-drying, the Hydrophobe Trousers complete your sailing thermal system — delivering warmth and performance without unnecessary bulk.

Ideal for: Sailing, dinghy racing, paddlesports and cold-water watersports
