This Navy Butter Goods Express Side Bag is perfect for urban explorers, students, and anyone who's always on the move. You can use it when you're commuting to work, going for a hike, or just running errands around town. It's a one-size bag that measures 24 x 41cm, so it's big enough to hold your essentials but not too bulky. With its nylon ripstop material, it can withstand daily wear and tear. The top-zip opening and mesh front pocket make it easy to access your stuff, and the adjustable shoulder strap ensures a comfortable fit.
