The Portwest KX302 KX3 Sport Hi-Vis Zip Polo Shirt represents the pinnacle of athletic-inspired high-visibility workwear, combining advanced moisture management technology with certified safety performance. Part of Portwest's innovative KX3 collection, this contemporary polo delivers the comfort and flexibility demanded by modern professionals who refuse to compromise between style and protection.

Engineered with Portwest's exclusive MeshAir™ aerated mesh fabric, this polo maximises airflow and breathability during physically demanding work. The moisture-wicking properties actively draw perspiration away from the body, keeping wearers cool, dry and comfortable throughout extended shifts. A slim fit design provides a form-fitting yet unrestrictive silhouette that moves naturally with the body.

The quarter-zip closure offers versatile ventilation control, allowing wearers to adjust airflow based on activity level and environmental conditions. Heat-applied segmented reflective tape provides enhanced visibility without the bulk and stiffness of traditional sewn-on strips, maintaining the polo's athletic character while ensuring workers remain visible in low-light conditions.

Certified to EN ISO 20471 Class 1 after 50 industrial washes, this polo maintains its high-visibility compliance throughout its working life. The orange colourway additionally meets RIS 3279-TOM requirements for UK rail industry applications, making it suitable for trackside and depot environments. A 40+ UPF rating blocks 98% of harmful UV rays, providing essential sun protection for outdoor workers.

The ribbed collar maintains a professional appearance while ensuring lasting shape retention. Additional thoughtful details include twin needle stitching for durability and an extended size range from S to 6XL, ensuring an optimal fit for all body types. Whether on construction sites, road maintenance, warehouses, or rail infrastructure, the KX302 delivers premium performance with certified safety compliance.

TECHNICAL SPECIFICATIONS

Q1: What makes the KX302 different from standard hi-vis polo shirts?

A: The KX302 features Portwest's exclusive MeshAir™ aerated mesh fabric and 4-way stretch Kingsmill™ Polyester Stretch construction, delivering athletic performance that standard hi-vis polos cannot match. The moisture-wicking technology, slim athletic fit, and quarter-zip closure create a modern workwear polo that performs like sportswear while meeting EN ISO 20471 Class 1 certification requirements.

Q2: Is the KX302 suitable for UK rail industry work?

A: Yes, the orange colourway of the KX302 is fully compliant with RIS 3279-TOM (Railway Industry Standard), making it approved for trackside and rail depot environments. The yellow colourway does not carry this rail certification. All colours meet EN ISO 20471 Class 1 for general high-visibility applications.

Q3: What does EN ISO 20471 Class 1 mean for this polo?

A: EN ISO 20471 Class 1 indicates this polo meets the minimum requirements for high-visibility clothing, providing enhanced daytime visibility through fluorescent material and night-time visibility via reflective tape. Class 1 is appropriate for lower-risk environments or as part of a layered hi-vis system. The certification is maintained after 50 industrial washes.

Q4: How does the MeshAir™ fabric technology work?

A: MeshAir™ is Portwest's advanced aerated mesh fabric system that creates strategic ventilation zones throughout the garment. The open-mesh construction allows air to flow freely, dramatically improving thermal comfort during physical activity. Combined with moisture-wicking properties, MeshAir™ actively pulls sweat away from the skin and accelerates evaporation, keeping wearers cooler and drier.

Q5: What UV protection does this polo provide?

A: The KX302 offers 40+ UPF (Ultraviolet Protection Factor), blocking 98% of the sun's harmful UV rays. This level of protection is classified as 'Excellent' and is particularly valuable for workers spending extended periods outdoors in construction, roadwork, landscaping, and other exposed environments.

Q6: What does 4-way stretch mean and why is it beneficial?

A: 4-way stretch means the fabric stretches both horizontally and vertically, allowing unrestricted movement in all directions. This is achieved through the Kingsmill™ Polyester Stretch blend (93% polyester, 7% elastane). The benefit is complete freedom of movement during physically demanding tasks like bending, reaching, and climbing, while the fabric recovers its shape without sagging.

Q7: Can I add my company logo to this polo?

A: Yes, the KX302 is specifically designed to be ideal for corporate wear and custom finishes. The smooth face fabric accepts both embroidery and printing, allowing for professional company branding. The slim, athletic fit creates a smart appearance suitable for corporate identity programmes across construction, logistics, utilities, and service industries.

Q8: What sizes are available and how does the fit compare?

A: The KX302 is available in sizes S through 6XL, offering inclusive sizing for all body types. The polo features a slim/athletic fit that is form-fitting yet unrestrictive. Those preferring a looser fit or who fall between sizes should consider sizing up. Refer to Portwest's size guide for specific chest measurements.

About the KX3 Collection

The Portwest KX3 collection represents a superior line of trend-led athletic workwear that combines quality construction to the highest standards with technically advanced fabrics. Key characteristics include abrasion resistance, moisture management, and stretch properties for sustained agility and effortless movement. Every KX3 garment is designed to complement the others, enabling workers to build a personalised layering system that maintains comfort across varying conditions.

Kingsmill™ Polyester Stretch Technology

Portwest's cutting-edge Kingsmill™ Polyester Stretch is a 4-way stretch fabric constructed from 93% polyester and 7% elastane. This blend provides exceptional ease of movement and effortless comfort during active use. The fabric delivers technical superiority with high breathability, moisture-wicking properties, and fast-drying performance. A UPF rating of 40-50+ blocks up to 98% of harmful UV rays, making it ideal for outdoor work.

MeshAir™ Ventilation Technology

MeshAir™ represents Portwest's approach to active cooling in workwear. The aerated mesh fabric creates open channels that allow warm, humid air to escape while drawing cooler air towards the body. This convective cooling effect dramatically reduces heat build-up during physical exertion, maintaining core body temperature for improved comfort, concentration, and productivity.
