Dainese have used its know-how in body mapping to develop D-Mantle Fleece WS, which has been optimised for motorbike riding but is also highly versatile and suitable for many other purposes. Thanks to the use of a thermal material and a fabric called"noWind"on the chest and at the back, the Fleece achieves 99% of thermal insulation, letting motorbike tourers keep their core temperatures intact even during extremely cold weather. The part that covers the thumb is made of elasticised fabric and the side zip increases the noWind effect by avoiding extra thickness to the jacket zip and offering improved comfort and ergonomics.
