When chilly weather hits or the temperature on your train is cooler than you'd like, make sure you pack the ExOfficio Women's Kelowna Lightweight Long-Sleeve Jacket in your carry-on. 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 hand pockets and interior drop pockets let you store your technology, passport, and other travel essentials with confidence. The 2-way zipper prevents the jacket from bunching when you bend down to reach for your suitcase or are seated on a plane. Thumb loops ensure the sleeves won't ride up.
