When chilly weather hits or the temperature on your train is cooler than you'd like, the ExOfficio Women's Kelowna Full-Zip Lightweight Hoody is a great just-in-case layer. Infrared yarns reflect your body heat back to your skin for warmth without weight. The wrinkle-resistant fabric will get you to your destination looking as crisp as the day you left, while the stretch construction lets you move easily. Zippered sleeve pocket and interior drop pockets let you store your technology, passport, and other travel essentials with confidence. Thumb loops ensure the sleeves won't ride up while you're exploring the city or go on an impromptu hike.
