our performance protects yours
We're not just workwear providers; we are innovators dedicated to pushing boundaries and engineering clothing that redefines excellence across multiple environments.
Alsico was founded in 1934 in Belgium and has since grown to become one of Europe's largest workwear providers.
We are innovators, wise to the fact that a company that sits still, never grows, continually searching for new solutions and technologies to further improve our products.
But we’re not just providing workwear; we’re enabling businesses to grow, supporting your teams so they can do the very best they can. Providing the garments you need to conquer every challenge. Because when you’re equipped with the best, you can achieve the extraordinary.

90 years of sustainable solutions
Our history
1934
Alsico’s beginnings
It all started in 1934 when Leopold Aelvoet decided to start his own company for professional workwear.
1947
Gaston Siau, the visionary
The small workshop that manufactured the first of the emblematic blue overalls was taken over in 1947 by son-in-law Gaston Siau. He expanded the company to a European workwear specialist. Aelvoet and Siau Confection thus became Alsico.
1975
First overseas production
In the mid-1970s, Mr. Gaston Siau was the first to start production overseas.
1982
The third generation takes great strides
Thanks to the vision and tireless work of the third generation - Bernard and Philippe Siau - Alsico grew to become a global player.
2016
Alsico Group with its fourth generation on board
In 2016, with Vincent and Gauthier Siau, the fourth generation joined the ranks.
2023
A new global brand
After many years of many brands across the world, Alsico moved to one single, unifying brand. A brand that captures the strength, scale and vision of the global company.
The future
A vision driven by performance
Moving forward, we have ambitious growth plans. Including more fabric technologies, our own fabric ranges, sustainability goals, and global expansion.
Global reach
nearly 100 years of experience in garment manufacturing
We have a team of around 7,200 employees within 21 factories in 11 countries over 4 continents. We truly are a global company with global reach.
All of our production units, with local management, are owned by the alsico group and exclusive to us.
The size of our global manufacturing operation means we can deliver the quickest lead times on the market today. We have full control of our supply chain and resources, therefore we can successfully manage the requirements of multiple contracts and clients across the world.
All of this gives us the capability to respond to your order and your delivery date in a timely fashion. If we don’t have the items you want in stock or if you have requested bespoke products, we have the manpower, the materials, and the infrastructure to deliver.
The alsico group is the largest purchaser of workwear fabrics in Europe, which not only helps us give you competitive products at competitive prices, it also enables us to source the most technically advanced fabrics available. Sourcing, developing, and bringing innovative workwear solutions to market is at the heart of what we do.
