Portwest Breathable Sun Shield Cap

Maximum sun protection, minimum weight. The Portwest Breathable Sun Shield Cap (HA22) is purpose-built for outdoor workers who spend long hours in direct sunlight, combining UPF 50+ UV protection, an integrated neck shade, and reflective visibility features in one lightweight, comfortable package.

Constructed from 100% nylon at just 110g, this is one of the lightest sun protection caps in the Portwest range. Nylon's natural strength-to-weight ratio means the HA22 delivers durability without any of the heaviness — you get a cap that holds up to daily outdoor use while feeling barely there on your head. The fabric is inherently quick-drying and resists moisture absorption, making it ideal for hot, humid, or physically demanding environments.

The standout feature is the UPF 50+ rating, which blocks over 98% of harmful UV radiation. This is the highest UPF classification available, offering excellent protection for the scalp, face, and — thanks to the integrated neck shade — the back of the neck and ears. These are the areas most frequently affected by sunburn and long-term sun damage on outdoor worksites, yet they're often left completely exposed by standard caps and hard hats.

The built-in neck shade extends coverage down the back of the head, providing continuous protection without the need for a separate accessory. It's a practical, all-in-one design that removes the hassle of retrofitting neck flaps or remembering to apply sunscreen to hard-to-reach areas.

Reflective piping across the cap enhances the wearer's visibility in low-light conditions — a valuable safety detail for early morning starts, late finishes, or overcast days where standard workwear can blend into the surroundings.

An adjustable toggle and bungee cord system at the back delivers a secure, personalised fit that won't loosen during movement or in windy conditions. No slipping, no readjusting — just set it once and get on with the job.

Available in two colours, the Portwest Breathable Sun Shield Cap is the practical, professional choice for anyone who works under the sun and needs protection they can rely on all day.

What does UPF 50+ mean? UPF (Ultraviolet Protection Factor) measures how effectively a fabric blocks UV radiation. UPF 50+ is the highest rating available, meaning the fabric blocks over 98% of both UVA and UVB rays. For comparison, a standard cotton t-shirt typically offers only UPF 5–10. The HA22 provides significantly more protection than most everyday fabrics.

How does the neck shade work? The neck shade is built directly into the cap and extends down from the rear to cover the back of the neck and ears. It provides continuous UPF 50+ rated sun protection to the areas most commonly missed by standard headwear, without requiring a separate attachment.

What is the Portwest HA22 made from? The cap is constructed from 100% nylon at 110g. Nylon is naturally lightweight, strong, and quick-drying — making it ideal for outdoor use in hot and humid conditions.

Does the reflective piping provide high-visibility certification? The reflective piping is designed to improve the wearer's visibility in low-light conditions, such as early mornings, dusk, and overcast weather. It is not a substitute for certified high-visibility garments where formal hi-vis PPE is required by site regulations.

How does the adjustable fit work? The HA22 uses a toggle and bungee cord system at the back of the cap. This allows you to tighten or loosen the fit quickly and securely, accommodating different head sizes and ensuring the cap stays in place during physical activity or windy conditions.

Is the HA22 suitable as a replacement for a hard hat? No. The Breathable Sun Shield Cap is a comfort and sun protection accessory, not a safety helmet. It is designed to be worn in situations where hard hat regulations do not apply, or during breaks and transit off site. For combined head and sun protection, consider pairing a hard hat with the Portwest Cooling Helmet Neck Shade (CV26).

What colours is the HA22 available in? The Breathable Sun Shield Cap is available in two colourways. Check the product page for current colour options and stock availability.

Who is the Portwest Sun Shield Cap best suited for? The HA22 is ideal for anyone working outdoors for prolonged periods — including construction workers during non-helmet tasks, landscapers, groundskeepers, surveyors, road workers, farmers, and utility teams. It's also popular for leisure activities like fishing, hiking, and gardening.
