HEYDAY is made from 17.5μ superfine merino wool—an exceptionally fine fiber.
Thanks to its ultrafine quality, it offers remarkable softness with minimal itchiness, making it gentle and comfortable even against bare skin.
The natural crimp structure of the wool traps air for excellent insulation while helping regulate moisture and humidity, keeping you warm and comfortable.
It can be used in a wide range of gauges—from 12-gauge with 1 ply to mid- and low-gauge applications by increasing the number of plies.
