The unique 50/50 blend provides the well known benefits of merino wool – super soft, naturally insulating and with exceptional temperature regulation; yet it also combines it with the added durability, stretch properties and wrinkle-resistance found in polyester fibres. The outcome is that this base layer is incredibly comfortable to wear against your skin, but it also has great longevity and will cope exceptionally well with repeat use and frequent washing — the perfect combination for winter cycling wear.
