What kind of fabric is the 'Polartec Alpha Direct 90' mentioned in the description?
When reading outdoor clothing descriptions, seeing a fabric name that mixes numbers and English can sometimes make it difficult to determine the actual thickness and characteristics of the garment.
It is an insulating material made without a lining that exposes fleece-like thermal fibers to reduce weight and allow air to pass through easily.
Looking first at the figure of 85g, this is a specification indicating that the fabric is thin and light enough that a 1m square piece of fabric weighs only 85g[1]. Polartec Alpha Direct improves upon the thermal insulation that was originally filled between the outer fabric and lining, reducing fiber shedding so it can be used on its own without a lining. The number 90 after the name refers to the approximate basis weight rating, and CAYL's pullover adopts an 85g/sqm specification woven from 100% polyester[2].
Thanks to the woven structure without an added lining, heat and sweat generated during activity quickly escape through the mesh-like gaps, and when layered under an outer garment, it traps an air layer between the fibers to retain warmth. The reason the Alpha Pullover is able to achieve a light weight of 145g for size S is also thanks to the design of this fabric, which eliminates the unnecessary weight of a lining[3].
Care standards regarding fabric shedding from washing or repeated friction have not yet been confirmed.
