IPX6 10L Waterproof & Buoyant Design: Shield your gear against heavy rain, sea waves, sand, and mud. Crafted from rugged, high-density 500D PVC fabric with airtight welded seams. The main compartment traps air when sealed, allowing the bag to float effortlessly if dropped overboard. Perfect for kayaking, paddleboarding (SUP), rafting, and beach days. Bonus IPX8 Waterproof Phone Case: Includes a premium, touch-screen friendly waterproof phone pouch that securely fits smartphones up to 7 inches. Give your device a double shield of defense by placing it inside the pouch and storing it safely within your floating dry sack. 3-Step Easy Roll-Top Seal: Engineered for maximum convenience and water ingress prevention. Simply flatten the stiffener, roll the top tightly 3 to 4 times, and click the heavy-duty buckle to form an instant watertight carry handle. Ergonomic Dual Backpack Straps: Unlike bulky single-strap bags, our 20L sizes feature two fully adjustable, detachable shoulder straps for comfortable backpack-style utility. The lightweight, scratch-resistant construction features reinforced cross-stitching at all high-stress anchor points. Quick-Access Splashproof Pocket: Features a front zipper pocket designed for rapid access to keys, sunscreen, or ID cards. (Note: The exterior pocket is splash-resistant for surface storage; always place electronics inside the main roll-top chamber for absolute waterproof immersion defense). Gear Up for Unstoppable Water Adventures Conquer any marine or outdoor environment with the Lamicall Floating Waterproof Dry Bag. Engineered specifically for high-intensity watersports and rugged outdoor travel, this 10L marine-grade dry sack acts as an impenetrable shield against heavy rain, sea waves, sand, mud, and dust. Whether you are navigating rapid river currents while kayaking, spending a sunny weekend boating, or packing gear for a beach day, your personal belongings will remain bone-dry, organized, and secure. Heavy-Duty 500D PVC Construction & Built to Float Crafted from premium, high-density 500D PVC fabric, this durable backpack is designed to withstand extreme environments without scratching, tearing, or wearing down. Featuring advanced high-frequency welded seams and heavy-duty, corrosion-resistant buckles, it provides elite surface waterproof protection. When sealed correctly, the roll-top system traps a large volume of internal air, giving the bag natural buoyancy that allows it to float safely on the water's surface if dropped overboard. Ergonomic Dual Straps & Bonus Touch-Sensitive Phone Pouch Unlike bulky, single-strap alternatives that strain your body over long distances, our spacious 10L storage sack features two fully adjustable, detachable shoulder straps. This design allows you to easily switch between a standard crossbody configuration and a balanced, comfortable backpack style. As an added value, each bag includes a premium IPX8 certified waterproof phone pouch that securely fits mobile devices up to 7 inches diagonally, maintaining complete touch-screen functionality for seamless underwater photo or video capturing. Simple 3-Step Airtight Roll-Top Seal Achieving absolute water ingress defense takes seconds. Simply flatten the top stiffener strip, roll it down tightly 3 to 4 times, and connect the heavy-duty quick-release buckles to create an instant watertight seal and a convenient top carry handle. The exterior also features a dedicated splashproof front zipper pocket, providing a rapid-access compartment for non-electronic essentials like keys, sunscreen, or ID cards. Upgrade your outdoor gear collection with the ultimate, all-weather carrying solution.
