Wear one jacket three different ways with our Men’s Citytrek 2L Rain Insulated 3in1 Parka. Transform an insulated puffer jacket into a waterproof rain jacket. The puffer jacket creates a warm layer, while the rain jacket keeps you dry so you can stand up to four seasons in one day. Wear the puffer jacket on its own, or the waterproof shell, or both – it’s up to you.
