You might have heard the word denier thrown around in the outdoor clothing or gear world, and wondered what it means. In this post, I will explain exactly what denier is, how it’s measured, and what it means for you when buying clothing or gear.
Denier is a measure used in fabrics to define the liner density of a particular fabric. This is done by measuring exactly how heavy a particular material is (in grams) for a length of 9000 meters (5.59 miles).
That may seem a little odd, but it helps to have large length of a particular material to get a reliable measurement. Especially when many nylons or polyesters are so fine.
