The Norrona Men’s Fjora Convertible Alpha60 Jacket is an insulated layer for winter biking. Mountain, enduro, single track or gravel, even mix in a little hiking or cross-country skiing. Keep your blood pumping and upper half warm while outdoors in the winter, without overheating all at the same time. Stretch fabric with wind- and water-resistance, you can bike hard through the trails. A 60g layer of Polartec Alpha insulation offers just enough heat, while still allowing you to breathe. Hit with a couple reflective blazes, it also keeps you visible in low-light situations.
