In a finer-needle knit than Heat Holdersusual chunky-knit thermal hats, this plain, smooth-knitted SOCKSHOP Heat Holders Rowan Hat is a versatile mens beanie that is no less insulating, and more than capable of keeping the cold out and the warmth in. The outer layer is created using Heat Holdershighly rated, high performance thermal yarn, while the inner layer is made from unbelievably soft and silky plush, fur-feel HeatWeaver fabric. The HeatWeaver thermal lining is designed to maximise the amount of warm air held close to your skin by capturing the natural heat coming from your head in its fibres. Both of the soft hat layers are thermally efficient, yet breathable, ensuring the warmth remains while moisture escapes, keeping you dry and comfortable as well as cosy.
