4

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.
4

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.
3

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.
4

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.

Warm packable mid layer

This mid layer jacket is very warm.I'm not trekking or climbing Everest bbut I do travel and go to football matches wearing a thin layer and this jacket as it's so warm. I love the zip pockets for security. It packs down in to the generous internal pocket but it could do with a zip to close it off. It was a bargain in the sale.

A disaster...?

The old jacket was brilliant, warm and yet "cold"..tried this new one and it was nothing compared to the old one. Froze like a dog on the bike to work today, 1 degree plus celsius...and it felt like I was wearing nothing...this version will probably only work in the summer...

Thank you for your feedback and we're sorry to hear the jacket didn't keep you warm on your commute!

The updated model has been redesigned as a lighter, more active layer compared to the original, so it's better suited to higher-output activities where breathability matters more than pure warmth. It sounds like the original may have been a better fit for your needs.

If you'd like to discuss a return or exchange, please get in touch and we'll be happy to help.

Stylish, Well Made and Very Comfortable

An excellent lightweight jacket - stylish and very comfortable, also well made and finished. I particularly like my chosen grey/mustard colour combination.
I'll definitely consider buying a Fjern garment again and will recommend to friends.
