The Jack Wolfskin Helium High Jacket is based on the incredibly popular Jack Wolfskin Helium Down Jacket it has the same high performance insulating duck down fill with a windproof and water resistant ripstop outer to keep you warm and protected from the chills but the main difference is that this jacket has a high collar rather than a hood making this a great jacket for colder months and for layering up Our favourite feature of this Jack Wolfskin jacket is the stowaway pocket you can stuff it into its own pocket so it takes up very little space perfect for keeping at the bottom of your rucksack so it is always close to hand when you need an extra layer to keep warm
