You'd expect any piece of kit named after Italy's toughest mountain to be pretty hardcore and Sportful's new jacket doesn't let the side down.
The Italian brand's new outer layer is so effective in fact that it has picked up an award at Eurobike: “The fit of the Stelvio Jacket is great, with its stretch material, perfect for athletes, such cuts for real cyclists are unfortunately too rare in the market,” said the judges.
Sportful have spent three seasons nailing down the details of the Stelvio, including a shedload of product testing with Tinkoff, the pro team they supply kit to.
The jacket was apparently inspired by the Gavia-Stelvio stage of the 2014 Giro d'Italia which stopped the peloton in its tracks amid severe snowstorms. If only they'd had a decent jacket ...
Sportful cranked into action with a brief to create a jacket offering full protection with the ability to be packed down to almost nothing, whilst taking into account fit and breathability. The result is a garment featuring Sportful's breathable 50,000g/m2/24h RainWick Stretch fabric that offers a close aerodynamic fit, double stretch cuffs that make it easier to get the jacket on and off and a waterproof rating of 20,000mm (that's quite serious).
What's more, at 165g it can not only be stowed into a jersey pocket, but you also won't know it's there and Sportful claim it can be worn in any temperature from zero to 20 degrees comfortably.
So it looks like Sportful have discovered the holy grail of rain jackets. The only question now is if you would even consider riding in the kind of weather that it is made for.
Available spring 2017 in Anthracite and bright yellow.
