Durable Water Repellent (DWR) is a chemical application that manufacturers use to create rain-proof gear, like rain jackets, rain pants, and waterproof backpacks. DWRs make water bead up, then disperse, preventing surface moisture from accumulating on rainwear. Even in a waterproof jacket, it is important that the surface doesn’t just keep water out, but pushes water away. If you have a soggy surface, your skin feels clammy and wet, even if the water does not actually penetrate the surface.

Primaloft® Black Insulation Eco is not only an excellent thermal insulator, but also resembles down in its lightness, breathability and fluffiness. Unlike down, however, it is much easier to maintain, machine washable, dries very quickly and is also suitable for allergy sufferers.
The filling is made of polyester fibres, and these fibres have a very high density, making the material very durable and suitable for more robust and heavier winter jackets with a membrane. Nevertheless, the filling is very soft, pleasant to wear and adapts to the shape of the body.
The specially designed polyester fibres are very fluffy and create a moisture wicking fabric, so you stay dry and warm even in extreme conditions.
The entire Primaloft® Black Insulation Eco filling is very fluffy and has an excellent warmth to weight ratio, so the jacket warms very effectively without having to be heavy or too thick, but it's also very easy to pack down to a minimal size so it won't take up extra space in your pack.

HELLY TECH® is the waterproof and breathable outer layer between you and the elements. Its unique membrane will keep water molecules out, while allowing sweat vapor to pass through – keeping you dry from the outside and comfortable on the inside.
