Give Breen jacket a go

Great buy, nice and cosy. Purchased some other products as well and are just as good and cosy

Nice warm but light jacket

Went for an XL and it fits true to size, I'm usually an XL in the majority of clothing, this fits snug, but not tight, enough to layer up underneath.
Nice bright bold blue colour. Very lightweight but surprisingly warm.

Fjern review

Great jacket for general winter use.

Bremen jacket

It’s a really good, comfy jacket. It’s super warm but also packs down nice and small meaning that when your out on an expedition, it doesn’t take up much space in your pack, but very good for when you get into camp. I highly recommend.

James Wilkinson
Brilliant jacket

This is a great jacket. The material is high quality and is very comfy to wear. I used it as a mid layer on a ski trip under a waterproof shell and it provided great warmth whilst also being breathable. The jacket fits well and remains comfy during activity. I would recommend this jacket and would definitely buy fjern products again
