Why put our bikes away for the winter when we can ride in chilly weather, thanks to the versatile 45NRTH Naughtvind Vest! With a suggested temperature range of 15-25F, the stretchy, double-weave shell resists wind and water while the stretch grid-fleece side panels increase breathability where we need it the most. It's warm enough for chilly days yet light enough to layer under our jacket on extra-cold days, making it a versatile layering piece for our winter rides.
