When we first came across this jacket at Salewa’s stand at Kendal Mountain Festival we couldn’t work out whether it was filled with down or Polartec/Polartec-like synthetic fibres. We asked one of the Salewa team there and were subsequently embarrassed to find out that it’s neither.
It’s actually mostly filled with wool. Tirolean wool to be precise, coming from a breed of sheep that’s able to survive all-year-round at over 2,000m above sea level.
As you have probably already guessed, this wool alone gives the Puez excellent insulation properties, but Salewa have gone one step further by adding a clever synthetic fibre called Celliant that takes things to another level.
They describe this as a ‘patented mix of thermo-reactive minerals’ that, when embedded within polyester fibres, is able to recycle heat that’s radiating from your body. It does this by converting it into infrared light, storing it and then slowly reflecting it back.

Clever stuff, but does it actually work? Our answer’s yes.
It’s a warm jacket that feels surprisingly lofty considering the nature of the fill, and it’s also light – not as light as some of the high performing down or synthetic filled jackets out there, but still pretty good at 587g.
Its outer fabric has a durable feel to it as well, giving the impression that it wouldn’t melt away with the smallest of embers hitting it, or tear when you’re pulling yourself over any rocky boulders.

It has an alpine fit that doesn’t feel too bulky, meaning that it can be worn comfortably underneath a waterproof shell, and it has an elasticated hood and cuffs. Then there’s the half length zip, which can be opened at both ends to give ventilation potential.
Pockets-wise, there’s one zipped kangaroo pouch on the front that’s harness-friendly and comes with a little stuff sack clipped inside it and there’s a zipped pocket on the breast plus two zipped mesh ones inside. So there’s plenty of storage space for anything from car keys and smartphones, to maps and sandwiches.
It’s worth us mentioning the steps Salewa have taken towards reducing the Puez Tirolwool Celliant’s environmental impact. First of all, they say that their desire to minimise the transportation footprint played a large part in their decision to choose wool from just down the road from their factory. Then they’ve also chosen a PFC-free DWR (no environmentally hazardous chemicals), and have been given Bluesign approval for their dyeing process.
If you’re looking for a standalone insulator for summer camping and for pulling on on a windy summit, or you’re looking for something that can be worn underneath a hardshell on cold and wet autumn days, this would be a good shout.
Not sure about the half zip? Well, good news is that it comes in a full zip version. There’s also a hoodless version, a gilet and more.

The amount of innovation here is admirable, so too is Salewa’s sourcing and manufacture process. I’ve used this a fair bit, and while the insulation and wet weather performance has impressed me, I’ve been equally endeared by its durability. It’s a very smart insulator.
