Understanding fabric weight
What does it mean when we see a fabric being measured by grams per square meter or "GSM"?
GSM is a standardized method to quantify the weight of fabric. Put simply the higher the GSM the heavier or thicker the fabric is. Merino Wool fabrics generally range from 100 gsm (ultra light) to 240 gsm (heavy).
Along with GSM, you may see our fabric specs listed with a micron size. This is a measurement of the diameter of the wool fibers at one thousandth of a millimeter. Merino wool fibers measure between 17.5 (Superfine) to roughly 25 (medium) microns. To put that in perspective, human hair is between 60-88 microns. The finer the fiber (lower number) the softer the fabric will be.

At Pinebury, we believe your clothing should perform as beautifully as the seasons themselves. Our Every-Season Merino Wool fabric is designed to adapt effortlessly to the demands of every climate, activity, and adventure.
