Linen towelling from Finland.

Linen towelling from Jokipiin Pellava in Finland is unique. It is made from 70% linen and 30% cotton: a rare proportion. The coarseness of the linen towelling has a massaging effect on the skin, but without scratching it. It stimulates the circulation and exfoliates at the same time. Jokipiin linen towels are the Scandinavians' first choice when it comes to sauna equipment, and with good reason.
Three-ply (500 g/sqm), 70% linen, 30% cotton. Warp (Nm 34/2) , cotton weft; (Nm 50/2); linen warp knit. Shrinkage 7-10%. Mashine washable at 60°C.
