These come in three sizes with a loose fit. Each size has a recommended user height and chest circumference. Understand that the fit is not like a parade dress or in any other way or form a socially normative choice.

The main thing to consider is the chest circumference, as a too-small shirt will be difficult to don. The length is generous and if the sleeves overshoot your hands, just fold them for a tailored fit.

Materials

We used to make these for a long time under the Jämä brand from army surplus blankets and other materials we happened to find, hence the name. The availability couldn't keep up with the demand, so these are now made from purpose-sourced materials as the Särmä Blanket Shirt. The wool fabric is the same as we use on our Woolshell garments: 70% recycled wool, 30% recycled polyamide, weight at least 400 g/m2, and the fabrics are made in Italy. 

Airing out will do the garment good and this is basically the regular "cleaning" you'll do. What comes to more thorough cleaning, as the first option it's best to try just brushing off any stains or spot clean with water and mild soap. If you manage to get this dirty as hell and absolutely need to use a washing machine, try a gentle wool cycle at 30 degrees Celsius (86 F). Use wool care products while you're at it, it'll make the garment restore its natural woolly goody features. Hang dry, stretch the garment out a bit while it's drying.
