An incredibly versatile insulated layer, constructed with a lofty 700 fill power down, yet lightweight and packable, and now made even better with 100% recycled nylon fabric.
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.

Please note: Down is exceptionally fine and can work itself through small openings, especially if the feathers become compressed. To keep your garment looking neat do not pull feathers through (this will make holes bigger), but tease them back in and rub the fabric to help seal the hole. For more information on caring for your down garment please see the Care section on the Fjern website.

Good quality jacket, bought a size up after seeing reviews, fits fine. Pleased with purchase, now to see if it lasts the test of time……..😊
Thank you for your review, Rob! We're happy to hear that you're happy with the quality of the jacket and that it fits well. We hope that it will continue to serve you well and keep you warm for many winters to come. Thank you for choosing our product, and we appreciate your feedback!
Best regards,
The Fjern Team
The jacket performed brilliantly on an 18 mile hike in the Peak District where we was greeted by every weather condition , hail , snow , rain , sunshine and blizzards. Quality product and would definitely recommend
Brilliant warm jacket, incredibly comfortable and lightweight but does such a great job of keeping you warm.
I am very pleased with the jacket and even more pleased with the company. Fjern were very generous in helping me resolve a stolen package. My only reason for four stars is the placement of the zipper on the left side. All my rain shells are right hand zippers and it is awkward to switch zipper strategies when removing layers.
Thank you for taking the time to leave a review, Bradley.
We're delighted to hear that you are enjoying your jacket and that you had a positive experience with our customer service team. It's interesting to hear about the chest pocket placement of your other jackets. The industry standard typically features a left chest pocket, and we currently do not have any plans to deviate from this. Apologies for the inconvenience this has caused you!
If you have any further questions or feedback, please feel free to get in touch.
Best wishes,
The Fjern Team
I’m pleased with this product overall. It would be great if they offered a mens xs. I’m 5’7” and it’s a little large for me.
