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 & suitable for many other purposes. Thanks to the use of a thermal material & a fabric called "no Wind" on the chest & 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 from elasticised fabric & the side zip increases the no Wind effect by avoiding extra thickness to the jacket zip & offering enhanced comfort & ergonomics.
