Depending on where the road takes you, fall travels can mean chilly temperatures. If you need to be prepared for crisp autumn air, Ecoalf has your outerwear needs covered. The Madrid-based sustainable fashion company makes a collection of down jackets using recycled plastic bottles, and the Uma coat for women is the warmest of the bunch. The Uma is long, descending beneath the rear at the back, and to the upper thigh at the front, keeping everything toasty in frosty fall conditions. The Uma coat is available in Yves Klein blue, deep navy, or khaki green.
