Ulanzi B011 Lightweight Single-Shoulder Bag 3L/4L

The Ulanzi Lightweight Bag B011 is a 235g polyester sling bag with a 3L capacity (expandable to 4L), featuring customizable DIY storage via removable dividers, Velcro access, waterproof exterior, velvet interior protection, rear zip pocket, and adjustable strap for shoulder/crossbody carry, ideal for compact camera gear on daily outings or travel.

The Ulanzi Sling Bag B011 offers photographers a versatile, low-bulk solution for transporting essentials, with dimensions of 230 x 110 x 180 mm providing a slim profile that fits mirrorless cameras, lenses, and accessories without excess volume. Its 3L base capacity expands to 4L via integrated expansion panels, while the DIY storage system includes a removable padded divider and multiple compartments secured by high-strength Velcro tape for rapid, tool-free reconfiguration accommodating setups from single-lens kits to multi-item loads. Constructed from durable polyester with a water-repellent PU coating, the exterior withstands light rain and abrasions, complemented by a soft velvet-lined interior that cushions gear against shocks up to 2m drops. Additional utility comes from a concealed rear zip pocket (100 x 50 mm) for secure storage of SD cards, batteries, or keys, and an adjustable nylon strap (up to 120 cm length, 25 mm width) with quick-release buckles for seamless switching between single-shoulder sling or crossbody configurations, distributing weight evenly (max load 3 kg). At just 235 g empty, the B011 prioritizes portability without sacrificing organization, making it a reliable choice for urban explorers or travelers needing quick-access protection.
