An incredibly versatile insulated layer, constructed with a lofty 700 fill power down, yet lightweight and packable. Warm enough to stand on its own in frigid, dry conditions but compact enough to be used as part of a layering system, the Aktiv is designed to accompany you on active alpine pursuits offering an extra layer of warmth. With a Nylon ripstop outer and an insulated & adjustable hood you'll be feeling confident as you strike out BEYOND BOUNDARIES.

Men's active down jacket

The first jacket that was sent out was labelled wrong size but this was soon sorted out without any issues( I don't understand the negative reviews) nice layer jacket that doesn't look cheap or make you look like a chav!!

Thank you, Martin.
