When it comes to waterproof riding gear, many riders immediately think of GORE-TEX®.
Known for its excellent breathability and waterproofing, it’s long been regarded as the gold standard—especially in premium riding apparel.
But here’s something worth revisiting: GORE-TEX® was not developed specifically for motorcycling.
It was originally engineered for active outdoor sports—skiing, trekking, mountaineering—where the body moves intensely and breathes heavily. In these conditions, high breathability is a major advantage.
In contrast, extreme wind resistance and water ingress under pressure are not the primary concerns.
But motorcycle riding is an entirely different story.
When you’re on a bike, your body is largely static, offering little movement to generate sweat. In regions like Malaysia, where high-speed highway riding through tropical downpours is an everyday occurrence, the riding environment places a whole different set of demands on gear.
The challenge isn’t breathability—it’s pressure resistance and durability.
Unlike hiking, riding at over 100 km/h in heavy rain means your gear is subjected to constant windblast that forces water into the fabric. Even a small puncture in the membrane can lead to failure.
Add to this the abrasion between your jacket’s armor and membrane layer, and it’s clear that motorcycle gear needs a different kind of resilience.
This is why some brands have developed motorcycle-specific waterproof membranes that prioritize long-term waterproofing and durability over sheer breathability.
Take H2OUT®, developed by SPIDI in collaboration with Toray® of Japan.
Unlike general-purpose membranes, H2OUT® was engineered for the real-world riding conditions that motorcyclists face—especially the combination of rain, wind pressure, and mechanical stress. It sacrifices some breathability in favor of lasting water resistance and structural integrity.
SPIDI garments featuring H2OUT® also incorporate strategically placed adjustable ventilation zippers, which allow riders to control airflow directly—achieving comfort through ventilation, not just membrane permeability.
The takeaway?
When shopping for your next waterproof jacket, don’t just look for the GORE-TEX® tag. Ask yourself:
What kind of riding do I do?
What kind of environment am I exposed to?
What is my priority when choosing riding gear?
Understanding the membrane technology behind your gear—and the riding context it was designed for—might just lead you to better, longer-lasting protection.
And that’s what really works on the road.
