Fjällräven Expedition X-Lätt Jacket

This, like an umbrella, fits one specific use case and yet is indispensable. I throw it in the bottom of all general-purpose bags rolled up in its built-in packing pocket to alleviate the simple, ever-present worry of being inconveniently cold. I used to dread office buildings in summer, drafty subways, and wind chill after a night out, resigning myself to chicken skin and quick steps. No more!
