    The overall weight of the garment. Lower ratings indicate heavier, more robust gear designed for extreme weather, while higher ratings mean lightweight options ideal for packability and speed-focused activities.
  • 3
    How effectively the fabric allows moisture and sweat to escape. Lower ratings suit low-output activities where warmth is the priority, while higher ratings are better for high-intensity activities, reducing overheating and condensation inside the garment.
  • 4
    How much warmth the garment provides. Lower ratings favour breathability and mobility, while higher ratings mean maximum warmth for extreme cold, often using high-loft down or synthetic insulation.
  • 2
    The garment's ability to keep water out. Lower ratings are for water-resistant or showerproof materials that handle light rain, while higher ratings signify full waterproofing with sealed seams and durable water repellent (DWR) coatings for prolonged exposure.
  • 3
    How well the garment resists wind penetration. A lower rating means the fabric allows some air movement for better breathability, while a higher rating indicates a near-complete wind barrier, reducing windchill in exposed conditions.
  • 5
    How compactly the garment can be packed. Lower ratings indicate bulkier items that prioritise warmth or durability, while higher ratings mean the garment compresses down small, ideal for fast-paced activities or lightweight travel.

Men’s Aktiv Down Hoodless Jacket

I had been looking for some time for this style jacket, I had looked at the Rab and the Patagonia and the Fjern was definitely the best for fit and value for money while being the same spec as the Rab and Patagonia. I’m so impressed I’ve ordered the body warmer version too!

Fab piece of outdoor kit.

Purchased this a few months ago and it’s now coming into its own with the drop in outdoor temperature. It fits well, very warm and looks awesome. It could do with a wash now to freshen up so what would one advise? Many thanks.

Thanks for the feedback! We're glad to hear you're enjoying the jacket.

As for washing it, we recommend using a down-specific detergent. You can machine wash it on a delicate, cool (30°C) cycle. Make sure to rinse thoroughly and spin on low speed. When drying, use a tumble dryer on a low heat with dryer balls (or a tennis ball in socks) to help restore the down’s loft. Alternatively, you can hang it to dry, but be sure to shake it occasionally to redistribute the down. Do not use fabric softener or bleach, and don't dry clean or iron the jacket.

Fianlly, make sure the jacket is completely dry before storing it.

Nice and Warm

I've had this jacket for about three weeks now, and it fits me perfectly. I've worn it with a baselayer and on its own, and it's kept me nice and warm. I wore it in a steady shower, and it held up well, but I haven't tried it in heavy rain yet. I didn't buy it for heavy rain, so we'll see how it goes. So far, it's met all my needs, and I'd definitely recommend it. No complaints from me!

We're glad to hear the jacket's keeping you warm and fits perfectly, Dave! It's great that it's performing well in lighter showers; however, it may not be the best choice for sustained heavy rainfall. We appreciate your recommendation and feedback!

Poor quality

Have this jacket about 3 weeks.
Already thread starting to come out of it in various places, including inside and also feathers pushing through in a lot of places.
I always wear medium, chest and shoulders fine but waist is too small .
Definitely not worth the price .

Dom, thanks for letting us know about the problems with your jacket. We're disappointed to hear that. Please reach out to us with your order information at support@fjern.equipment so we can find a solution.

Amazing jacket. Great for casual use or more extreme use. I used it as a soft shell layer in -13 a couple weeks ago and it was perfect. Nothing wrong with it whatsoever.

Too Small

I ordered this jacket in the maximum XXL size and unfortunately it appeared to be two sizes below that ie large. The quality of the jacket seemed really good and I would have given it 5 stars if the fit was correct.

Great jacket, sizing an issue

The product is well made and there are no defects visible. However the sizing is not good. I bought a XL and it fits more like a tight Large or medium. Go for a larger size!!!

Hi Andrew,

Thanks for your interest in our Aktiv Jacket. We're in the early stages of a re-stock, and our earliest estimate for availability is around September.

The sizing is a little confusing. I'm a 40" chest usually so I'd expect to go for a Large size. However when I laid out another jacket and compared it to your garment laid flat measurements it seems very broad at the chest. Are the 2 size charts Aligned? What us a 40" to 42" chest size normally please?
Thank you!

Fjern

Hi Rob,

Thanks for your question.

Please refer to the 'Size Guide' for your body measurements, and the 'Garment Measurements' for the product's measurements.

A 40-42 inch chest aligns with size L. If you usually wear a large, you should find a comfortable fit with our Aktiv in size L.

Kind regards,
The Fjern Team

Does this come with its own storage bag?

Fjern

Hi Dominic,

Thanks for your question. The jacket does not come with it's own storage bag, instead, one of the outer zipped hand pockets doubles as a stuff sack.

All the best,
Fjern Team
