In the latest Shackleton Briefing, explorer and product designer Charlie Smith introduces Active Insulation, our newest category of softshell jackets.

Tuned for moving fast and light from the valley to the summit, our Active Insulation range provides highly breathable, windproof jackets for all-day adventures. Erebus Jacket and Hawkes Gilet are made from recycled ripstop outer fabric and Clo VivoOcean insulation with patented perforations for 30% greater breathability.

Harness-compatible and technically adaptable for multiple activities, they excel as both windproof outer layers and mid-layers within a three-layer system whether you’re fastpacking in the Lake District, climbing fourteeners or ski touring in the Alps.
