When winter blows in, we pull on the Fjallraven Keb Agile Winter Trouser and trek out to see how the cold and the snow have transformed our favorite trails into something new. We zip the cuffs over our boots and latch the hook onto our laces to stop snow from packing in. As we explore, the reinforced inner hem increases abrasion-resistance against our spikes, while the articulated fit and stretch keep us moving freely.
