how alsico’s Makalu fabric is helping protect outdoor workers from skin cancer
Every day, millions of outdoor workers face hidden risks that go far beyond immediate job site hazards. One of the most serious? Long-term exposure to harmful UV rays. For those in construction, rail, and utilities, extended time in direct sunlight can significantly increase the risk of developing skin cancer, especially on areas of the body that remain exposed despite PPE compliance.
high-vis clothing designed for
visibility, built for protection
Our mission has always been to protect the people who keep the world running. That is why we developed Makalu, our high-visibility fabric that exceeds basic safety standards.
Powered by ALSIFLEX® stretch technology, our innovative Makalu fabric delivers the perfect balance of flexibility, comfort, and environmental impact. This ground-breaking fabric is made from recycled and bio-based fibres, offering alternatives for the modern workforce that require high vis clothing.

high-vis workwear with UPF 50+ protection
Makalu is designed with UPF 50+ sun protection, creating a reliable barrier against ultraviolet radiation. Only 1/50th of UV rays are able to penetrate the fabric, which greatly reduces skin exposure and supports long-term skin health for outdoor workers who spend hours in the sun.
Unlike ordinary high-vis garments, which may fade, wear out, or provide little UV shielding, Makalu offers durable, dependable protection without compromising comfort or compliance.

a smarter approach to PPE
Too often, sun safety in the workplace is treated as an afterthought, a poster on the wall or a seasonal reminder. Sun protection should be built directly into workwear.
Makalu goes beyond visibility and UV resistance. The fabric combines UPF 50+ sun shielding with lightweight breathability and built-in stretch, giving workers the freedom to move comfortably through demanding tasks.
By integrating safety, comfort and flexibility into every garment, it delivers on the promise that performance protects yours.
comfort meets compliance
Makalu is not only protective, it is designed for all-day wearability. The fabric is lightweight, breathable, and offers built-in stretch, making it ideal for challenging outdoor environments. It provides high visibility in both daylight and low-light conditions while keeping workers cool, comfortable, and protected from harmful sun exposure.
protecting more than the job
Skin cancer is one of the most common and most preventable cancers worldwide. For employers, reducing sun exposure for their teams is not only a legal responsibility, it is a moral one. With alsico’s Makalu garments, protection from UV radiation becomes part of the uniform itself. It is a seamless element of everyday workwear that provides peace of mind and can make a life-saving difference. Our specialists work with you to design and deliver the right protective garments for every role and environment, ensuring your teams are safe, comfortable and compliant.
