Dainese have used their know-how of body mapping to include a second layer on the D-Mantle Fleece WS. This fleece has been optimised for use on a motorbike but is highly versatile & can be used for many other purposes. Thanks to the use of a thermal material & a fabric known as ""no Wind"" on the chest & at the back, the D-Mantle Fleece WS achieves 99% of thermal insulation so letting motorbike tourers keep their core temperatures intact even during extremely cold weather. The part that covers the thumb is in elasticised fabric & the side zip increases the no Wind effect by not adding extra thickness to the jacket zip & instead offers enhanced comfort & ergonomics.
