As the cleverest probably picked up, the Finnish army model sweater is strikingly similar to the British army model which it indeed is copied from. Why not, it's a superb sweater and looks good on you. One-off lot!
100% thickish wool, with polycotton reinforcements on the shoulders and elbows.
Being wool, usually airing out is enough to keep this fresh. If, however, you have to wash it, do it in about 30 degrees Celsius and preferably by hand.
Sizes in the classic "T-shirt style", just pick what you usually wear. Additionally we have given the comparable EU sizes for each. The sleeves are meant to be folded at the cuffs to proper length (and the folds "find their place" over time), so these are very long, fit for most people. The fit is snug at first, but this will form to your body.
This British company has been making these for a long time, quality stuff overall.
A company called Inttistore went under and we bought the whole stock, that's where these are from. These are cheaper across the board than they originally retailed for, and present excellent bang for the buck.
