Brew it bold.

To watch the world wake up with the sun is like observing an infant learning how to walk; the squirrels have unsure footing, leaves slip sleepily off tree branches, and the sun doggedly spills over into the yard. One thing's for sure, the Fjallraven Koster Sweater for Men was made for mornings spent sipping coffee on the porch, monitoring the daybreak's timeless moments. Crafted with 100% soft wool, this sweater has a chevron, half-zip collar, G-1000 reinforced shoulders, and a dapper chest pocket—making it the ultimate closet classic.

Really warm.

Really warm. So far so good. Fit in the body and sleeves was a bit short, but I stretched it after a wash and it fits well now. Neck is a bit odd: too long to zip up straight, not quite long enough to be a turtle neck, but overall a good purchase.

Love it!

I just received my Koster Sweater, I thought the arms would be too long as my arm length measurement was 2 inches shorter than the S size arm length in the size guide but this sweater is beyond perfect. The fit is great, I wear small size everything and this sweater is perfectly sized to be able to fit a base layer and a secondary thicker base layer if I need to. The neck is extremely tall, if you zip it to the tip it'll almost reach your ears. I have a beard and a thick-ish neck so it's tight when zipped up. The neck being tall does feel weird when trying to style this casually. I tried it on with my Fjallraven Vidda Pro jacket and the neck bit looks funny poking up so high, but when paired with my Levis Sherpa lined jacket the tall neck is super stylish! I specifically find the G-1000 reinforcements at the shoulder and elbows super nice. This sweater feels as durable as everything else from Fjallraven. Can't wait to layer this on an extremely cold day.

Koster Sweater

I have had this fab sweater for nearly a year. It has been washed only once as the wool does not smell after being worn unlike synthetic materials and it still looks great. The quality of the materials used and construction is very good. I hand washed at 20*C and let it dry naturally. There was no shrinkage though it does "pill" a little bit but these can be removed with a fuzz away gadget if they bother you. It is a bit itchy if you wear it next to naked skin but with a base layer or technical teeshirt underneath it is very comfortable. It is warm and I have had to take it off quite a lot whilst walking or gardening. It also looks cool with the smartest of clothes or shorts and flip flops. I'm hoping that we get some cold weather in the UK sometime soon, so I can actually wear it more. Quite expensive but you really do get what you pay for in this instance. I have no doubt that this jumper/sweater will last me a long time. 5 Stars.

Solid Wool Sweater.

Just a simple wool sweater that is put together well, looks like it will last a long time. Fit is a little loose but that should adjust over time with cleaning.
