Moleskin is a heavy cotton fabric, woven and then sheared to
create a short, soft pile on one side. The cloth is woven of carded cotton yarn
in a dense weft-faced satin weave. The surface is napped or sheared to
"produce a suede-like finish".
The feel and appearance of its nap is like felt or chamois,
but less plush than velour.
Clothing made from moleskin is noted for its softness and
durability; French workers of many generations wore ("bleu de travail") workwear
made of moleskin. The cloth is so densely woven as to be windproof.
Its name is due to the soft brushed hand of the fabric, like
mole fur.
