But that's not quite the end of the story, because fill weight is important too… What is fill weight?Extreme winter conditions: winter and alpine mountaineering, high altitude climbing, polar expeditions Insulation:800FP European Goose Down with Nikwax Fluorocarbon-Free Hydrophobic Finish (250g / 8.8oz, Size M) Stuffed with 650+ FP down (certified by the Responsible Down Standard but at the upper end of what we’d class as ‘entry-level’ in terms of fill power) the Janhukot tips the scales at 800g, so it’s no lightweight. It’s also pretty chunky, with large baffles and a fairly boxy silhouette. You’d struggle to wear it under a shell, so this is certainly not intended to work as a midlayer. Instead, it’s designed as a standalone barrier against the cold. And in that regard, it does a very good job. Indeed, its sheer heft makes it feel extremely cosy. Best uses: winter hillwalking, winter country walking; trekking; climbing; mountaineering; urban use.

Surrounding all this luxurious insulation is the new 13D Gore-Tex Infinium Windstopper membrane. This new membrane provides complete wind-proofing, high levels of breathability and excellent weather resistance. Technically this membrane isn't 100% waterproof, but in practice we've found that only prolonged torrential rain will eventually seep through.
