March 16, 2024 | Helly Hansen



As outdoor enthusiasts, we all know the importance of staying dry and comfortable during our adventures. Whether we're hiking through the rainforest, skiing down snowy slopes, or sailing across choppy waters, having reliable rainwear is essential for enjoying the great outdoors.  

But with so many waterproofing technologies on the market, it can be challenging to decipher which ones offer the best protection and performance. In this blog, we're diving into the world of Helly Tech® – a leading waterproofing technology developed by Helly Hansen.  

From its innovative design to its practical applications, we'll help you make informed decisions when choosing your next outdoor gear.

So, what is Helly Tech®? 

Helly Tech® is a proprietary waterproofing technology developed in the 1980’s by Helly Hansen.  

Helly Tech® utilises a laminate membrane that is bonded to the outer fabric of clothing or gear. This membrane acts as a barrier to prevent water from penetrating the material while allowing moisture vapour to escape. This breathability is crucial for regulating body temperature and preventing the buildup of sweat and moisture inside the garment. 

A unique feature of Helly Tech® waterproof technology is the reduction of harmful chemicals, such as PFC (polyfluorinated chemicals) commonly used in the production of many outdoor textiles. Across the Helly Tech® range you’ll also find most of our garments are bluesign® certified and incorporate OceanBound recycled materials.  

bluesign® certified materials and products meet stringent criteria for resource efficiency, consumer safety, and environmental protection. This includes requirements for energy and water usage, chemical management, air emissions, and worker safety. 

Is Helly Tech® right for me? 

This answer depends on a few factors, one of the most significant being the intended use of your gear.  Helly Tech® can be broken down into 3 levels, each serving a different purpose and level of protection.

Although a fabric technology's waterproof rating is important, it's not the sole factor determining weather protection. Design details like seams, vents, zippers and pockets can make or break a jacket’s performance. 

The key feature of Helly Tech® is its ability to keep you dry and comfortable in wet conditions. Whether you're hiking in the rain, skiing in the snow, or sailing in windy conditions, Helly Tech® gear is designed to withstand prolonged exposure to water and wind while keeping you dry on the inside.
