Some like it rough...
Linen towels from Austria:
coarse and soft.

The looped threads of this heavy 520 g/sqm towelling fabric made from cotton and linen produce contrasting effects: the top side is made from equal quantities of cotton and linen. It has the characteristically coarse feel of a linen fabric, which stays firm even after frequent washing and maintains the lasting massage effect of the towel. The loops on the reverse are pure cotton and are smooth against the body. Please note the difference of this fabric to the simpler but more widespread two-ply towelling. The three-ply used on the reverse side is a lot softer and has more volume.
Three-ply towelling (520 g/sqm) made from 70% cotton, 30% linen. Warp knit. Top side Nm 34/2, reverse Nm 28/1. Lower warp cotton thread Nm 40/2.
