SEALSKINZ Langham Waterproof Unisex Running Cap, Black, One Size, V2 — SPF 40+ breathable Aquasealz

SEALSKINZ Langham is a lightweight, fully waterproof unisex running cap with breathable Aquasealz membrane and SPF 40+ sun protection.

The Langham cap blends weatherproof performance with casual style so you can run, hike or commute without stopping for a downpour or intense sun. Built from a three-layer polyester construction and SEALSKINZ’s patented Aquasealz technology, it keeps external moisture out while letting heat and perspiration escape. An adjustable buckle-clip closure helps you dial in the fit, and the cap is designed for easy machine wash care.

How does this cap keep water out while staying breathable?

The Langham uses a waterproof Aquasealz membrane layered between polyester fabrics to block rain and spray. Unlike simple coated caps, the membrane vents internal moisture so you don’t feel clammy during sustained activity.

• Three-layer construction with sealed seams for reliable waterproofing
• Aquasealz membrane allows vapor transfer to reduce sweat build-up
• Lightweight polyester outer resists wind and splatter without adding bulk

Will it protect me from the sun and harsh light?

Yes — the Langham offers high UV protection rated at SPF 40+, helping to reduce solar exposure to your face and scalp during outdoor sessions. The peaked brim gives additional shade while maintaining a low-profile technical look.

• SPF 40+ fabric for UV defence during long outings
• Structured peak shades eyes without blocking airflow
• Available in muted colourways that coordinate with outdoor gear

How should I size and care for the cap?

The cap is one-size with an adjustable buckle clip and fits up to a 58 cm circumference measured above the eyebrows. For a more comfortable fit if you normally prefer a looser cap, consider choosing one size larger where available.

• Adjustable buckle closure adapts to most head sizes up to 58 cm (22.8")
• Machine-washable at 30°C/85°F; drip dry recommended
• No special detergents needed; avoid high-heat drying to preserve membrane

What makes the Langham suitable for everyday use as well as performance days?

The Langham balances technical features with a streamlined, urban-friendly silhouette so it works equally well on a trail run or a rainy commute. Its lightweight feel and packable design make it easy to stash in a pack or bag until needed.

• Low-profile look that pairs with performance kit and casual wear
• Lightweight and packable — won’t crush easily in a bag
• Durable polyester construction built for frequent wear and wash cycles

Who is this for? The SEALSKINZ Langham cap is designed for active men and women who want dependable waterproofing and sun protection without sacrificing breathability or style. It’s ideal for runners, hikers, cyclists and anyone who needs an all-weather, easy-care hat that performs during both short outings and long days outdoors.
