Nanuk Ecosphere 100

Fleece fabric

Nanuk Ecosphere is the sustainable version of our fleece because it is made of 100 % recycled polyester.

Nanuk 100 is a polyester fleece (100gsm), meaning 100 grams per square metre and ultimately indicates moderate level of insulation.

Our fleece is generally breathable and quick-drying.

Nanuk means polar bear in the Inuit language and is fleece technology developed exclusively by JACK WOLFSKIN.

The fleece weight is given in grams per square metre. The higher the number of grams, the warmer the fleece.
