Whether you're biking to work or around town, the Patagonia Ultralight Black Hole 8L Sling Bag offers easy everyday storage and a comfortable wear. The asymmetrical sling-style harness won't bounce around or slide when you're riding hard on the road, and the expandable stretch pocket on the strap will keep a phone or energy bar close by so you won't have to slow down to reach for the essentials. Offering eight liters of storage and a dual-compartment design, this bag has enough space to fit your smaller daily essentials items, while the durable ripstop fabric delivers solid water-resistant protection to keep your stuff protected in rainy weather. Plus, you've got breathable mesh on the strap and back panel to help keep you cool when those summer storms give way to hot and humid weather.
