I’m a big fan of Uniqlo’s ultra light collection. These jackets are warm, waterproof, and easily layered. Perhaps their best feature is their ability to fit in a small pouch. The pouch offers portability and compactness; it’s the perfect item to throw in a carry-on suitcase or in my backpack as I’m running to class. I don’t know how Uniqlo does it, but this jacket has become an absolutely essential part of my wardrobe.
