SALEWA Puez TiroWool Celliant

RRP: £195 Target price: £160 At 515g this is the heaviest jacket in our test – and it proves our point about weight not equalling warmth, as the Rohan, Rab and Berghaus jackets are definitely warmer per se. But that extra weight isn’t troublesome on the go, and the jacket is more about temperature regulation rather than outright heat. At the heart of it is TiroWool Celliant, a hybrid insulation that blends wool from Tirolean sheep with a synthetic polyester yarn. It makes an extraordinary claim: that it “recycles radiant body heat into infrared light and converts, stores and reflects it back to the body.” It scores highly on aesthetics too: it’s sharply sculpted, with neat jazzy flourishes, and you may lose count of the times someone says “nice jacket” in its presence. I tested the hoodless version, and in fact missed the hood when caught in severe gales on the Eildon Hills, but you can get a hooded version for the same price. So although it’s not warm enough for wildlife watching or photography (where you stay still), it’s pretty much flawless when it comes to on-the-go heat management. NH
