Ultralight down insulation for any British winter
Peak Performance built the Helium range on a simple idea: down insulation should keep you warm without weighing you down, literally or figuratively. This version packs 700 fill power duck down into an ultralight nylon ripstop shell that’s wind and water resistant, tipping the scales at just 340g – light enough to stuff in a daysack and forget about until the temperature drops. The two-way adjustable hood and elastic cuffs keep the weather where it belongs, outside, whether you’re walking the dog along a frozen towpath or waiting for a delayed train on a windswept platform. It comes with a repair patch included, because good gear should be fixed, not binned, and the recycled fibres and responsible down standard mean it’s kinder to the planet than most jackets this warm. A genuinely versatile layer for anyone who feels the cold.

The purchase of RDS certified products demonstrates demand for better animal welfare practices in the down and feather supply chain. Peak Performance is certified to the RDS.
Peak Performance started with two skiers on a chairlift in Åre, wondering why nobody made kit that worked as hard as they did. Forty years on, that same stubborn Scandinavian practicality runs through everything they make – gear built to survive the sort of weather that makes you question your enthusiasm for the outdoors, without looking like you’ve raided a search-and-rescue team’s locker. There’s a reason the motto “if it can handle Åre, it can handle anything” has followed them since day one. Reach for the brand’s Helium jackets on frost-bitten dog walks, stick one in your pack for the inevitable change in conditions halfway up a Lakeland fell, or layer it under a shell for reliable core warmth. Scandinavian minimalism meets genuine mountain pedigree – no fuss, no filler, just gear that gets on with the job.
