A softshell hiking jacket you can use as an inner jacket? For sure – it's got a System Zip which means you can zip it into any compatible shell jacket. Worn on its own, the Womens Essential Altis Softshell Jacket from Jack Wolfskin has been designed for spring trails, summer adventures and autumn hikes in predominantly dry weather. Combined with a weatherproof jacket it offers all–round protection with basic thermal insulation. The softshell has a slightly longer cut and fits like a second skin, thanks to the exceptional stretch characteristics, soft microfleece reverse side and excellent breathability.
