The DrystarXF membrane uses a laminated construction that fundamentally changes how waterproofing works in motorcycle jackets. This isn’t your typical removable waterproof liner – the membrane is directly laminated to the outer shell material.13 The “XF” stands for “extra flow,” which tells you exactly what sets it apart from standard waterproofing technologies.1
Unlike traditional membranes that can get waterlogged and heavy, DrystarXF prevents water from penetrating or soaking through the shell. I’ve ridden through some serious downpours, and the jacket stays lightweight and comfortable instead of becoming a soggy mess.15
Waterproofing | Delivers | Real-World Protection
The DrystarXF membrane incorporates hydrophilic technology where water vapor gets absorbed from your body and released to the outside.3 This two-way process creates an effective barrier against external moisture while allowing internal humidity to escape.
In practical terms, this means you stay dry from both rain and sweat. The membrane keeps water from getting in while simultaneously allowing the fabric to breathe.1 This balance is crucial for long rides where comfort directly impacts safety through rider fatigue.
Breathability | Creates | Climate Control
What impresses me most about DrystarXF is how it manages temperature regulation. The membrane works alongside strategic ventilation features:
- Direct ventilation ports on front and back
- Zippered air scoops on forearms
- Super-airflow panels on front zipper openings135
These ventilation options can be operated with one hand for quick climate control while riding.36 I’ve found this particularly useful when riding through changing elevations where temperatures can vary dramatically within minutes.
Construction | Enhances | Riding Experience
The DrystarXF membrane contributes to the overall lightweight design of jackets like the Hyde XT, Monteira, and AMT-10Lab. The membrane’s laminated construction eliminates bulk while maintaining protection.
The membrane’s fast-drying properties mean you’re not stuck with damp gear after the rain stops. This practical benefit can’t be overstated for multi-day tours where you don’t have the luxury of waiting for gear to dry.
Technical Performance | Exceeds | Traditional Waterproofing
DrystarXF offers several advantages over traditional waterproofing approaches:
| Feature | DrystarXF | Traditional Waterproofing |
|---|---|---|
| Water Resistance | Prevents penetration and absorption | Often absorbs before repelling |
| Weight When Wet | Remains lightweight | Becomes heavy and waterlogged |
| Drying Time | Fast-drying | Often requires hours to dry |
| Breathability | Maintains breathability when wet | Often loses breathability when saturated |
| Windchill Protection | Blocks wind effectively | Variable performance |
The DWR (Durable Water Repellent) treatment applied to jackets with DrystarXF provides additional wet-weather performance, creating a first line of defense that complements the membrane’s capabilities.36
DrystarXF represents a significant advancement in motorcycle apparel technology, delivering protection without compromise. Whether you’re commuting daily or embarking on a cross-continent adventure, this membrane technology provides the versatility modern riders demand.
