Alf tests one of the lightest shell jackets on the market - the Helio by Black Diamond.
WEBSITE: Black Diamond
WHAT THEY SAY: "A ski mountaineer and ultralight alpinist’s dream jacket, the Helio Shell is our lightest GORE-TEX jacket and the king of packability. With an all-new GORE-TEX C-Knit backer, the crispy feel of most hardshells is replaced with a soft-to-touch construction that increases comfort on missions where luxury is a premium."
WHAT ALF SAYS: The Helio Shell is the lightest of Black Diamond’s three-layer shells, weighing in at just 370g – this means you barely notice it whether wearing or carrying it in your pack, and it also packs down very snugly too. All of this makes it ideal for ski tourers, ski mountaineers and alpinists.
