Wool inspires in us a very intimate relationship. We all instinctively rub cashmere or extra-fine wool against our cheeks to feel their sensual softness. We recognize a knit’s quality—a certain lightness and softness—by touch.

This quality is measured in microns. A micron, or one-thousandth of a millimetre, is used to measure a fibre’s diameter. The better the quality and prestige of wool, the lower the number of microns, which is determined by the place on the animal where the wool was sheared. An ultra-fine wool of 16 or 18 microns, for example, is so soft that it can be worn against the skin. When you don ultra-fine wool clothing, you’re never too hot or too cold.

The airy texture adapts to your body temperature and your environment, ventilating indoors and offering thermal protection outdoors. The result? Our fine-micron wools never itch! A higher micron does not necessarily mean more warmth, however. Fine-micron yarn offers insulating and absorbing properties that make it warmer than large-micron, thicker wools. ça va de soi chooses yarns that measure between 15 and 19 microns, a rare standard of quality in the world of knits, where the average hovers around 24 microns.

Even our oversize, enveloping sweaters are made of fine fibres that we double or triple to help you survive the cold in complete comfort. Wools are also distinguished by the technique used to prepare them for spinning, either carding or combing. Our cashmere and virgin wool are carded fibres, for more warmth and durability and for a more rustic finish. Our extra-fine merino falls into the category of combed wools, which are more refined since they look perfectly even. The style of knit dictates the choice of technique.
