The technical winter jacket: Sorona® insulated and waterproof

The James & Nicholson JN1815 Pro Multi-weather winter jacket brings two functions in one: insulation and protection. Its DuPont® Sorona® padding (fibres from renewable resources) retains warmth, while its 10,000 mm waterproof and 5,000 g/m²/24h breathable membrane blocks rain and wind. Built for manual work in the cold season, it is made of 100% recycled polyester (PET bottles), with a stand collar, removable hood, sealed seams and zips and reflective strips.

Notre avis Grand Froid

We like that it does everything in one piece: Sorona® insulation keeps you warm, the 10,000 mm membrane keeps you dry and blocks wind, and the breathability avoids the sauna effect during effort.

On the ground, everything is work-focused: sealed seams, waterproof zips, reflective strips, inner elastic cuffs, drawcord and a removable hood. And the 100% recycled eco-design is a real bonus.

When to wear this jacket?

This winter jacket is particularly suited to:

Manual work outdoors in the cold season
Wet and windy conditions (rain, snow)
Outdoor activities in bad weather
A single insulated and waterproof piece, without adding a shell
Environments where visibility matters (reflective strips)

Thermal protection

This jacket insulates AND protects in a single layer: Sorona® padding for warmth, 10,000 mm / 5,000 g/m² membrane for water and wind. In deep cold, add a warm mid-layer (fleece) and a thermal base layer. The use temperature is not stated by the manufacturer; felt warmth depends on the layers worn underneath, wind and humidity.

How to use it well?

This jacket already combines insulation + protection (2nd and 3rd layers). For deep cold, complete it as follows:

1st layer (Transfer): a breathable thermal base layer
Mid-layer (in deep cold): a light fleece to boost insulation
JN1815 jacket (Insulation + Protection): Sorona® padding + 10,000 mm membrane as the outer barrier
