The Uber Storm Interactive Coat. This shorter length version of the Storm coat has the same exceptional construction features & outer fabric. However it differs slightly by having a hood that rolls-away into the collar, & insultion that is an integral part of this jacket. Glossary Prima Loft One (Primaloft One* 60g body/40g sleeves). The ultimate microfibre insulation, it has one of the highest warmth-to-weight ratios of any synthetic insulation. Ultra fine fibres are specially treated & then combined into an insulating core that is incredibly soft, lightweight & water resistant.
