Exceptional trekking jackets require exceptional materials …
Duuton®3 - Naturally Comfortable Weatherproof Protection™
Made in Switzerland, Duuton®3 is a no compromise - 100% premium cotton - technical outdoor fabric.
The special extra long staple (ELS) yarns - for superior strength - and precision high density weave protects against wind, rain, snow and sun, yet remains incredibly durable, breathable and comfortable. Its low maintenance micro construction dynamically expands when wet to repel foul weather without the need to add wax or oils. Being unimpeded Duuton®3 maintains its full breathability with a rustle-free comfort and performs across an extreme diversity of weather conditions and temperatures.
We use 200g Duuton®3 throughout the TREK MKII jacket.
ELS cotton fibres are only available from around 2% of the world's entire cotton crop, but due to their naturally long length this creates yarns of superior strength as they can be spun using an exceptionally low twist. To then create the tightly woven high density textile takes several more hours of skilled labour resulting in a particularly strong fabric with excellent dimensional stability, a superior lustre and a visibly smoother finish.
Duuton®3 is also treated with a special Durable Water Repellent (DWR) finish to improve drying times and help repel moisture.
