Key Features
- 500 Denier Waterproof PVC Construction: Crafted from heavy-duty, abrasion-resistant PVC with sealed seams, providing long-lasting durability and reliable water resistance in wet environments.
- Lightweight Build: Weighing just 2.3–2.5 lbs (depending on size), it minimizes fatigue during extended use without compromising strength.
- Padded Comfort System: Features EVA foam padding on the back panel and thick, cushioned shoulder straps for all-day comfort. The adjustable sternum strap helps distribute weight evenly across your chest, reducing strain on your shoulders and back.
- Dual Roll-Top Sealing Options: Secure the roll-top closure using either the top clip for quick access or side clips to compress the bag tightly—offering IPX-6 waterproof protection in both modes. This flexibility lets you adapt to changing needs while maintaining full weatherproof performance.
- Exterior Splash-Proof Pocket: A large front pocket designed to keep frequently accessed items—like keys, IDs, or a phone—safe from light rain and splashes, with reflective trim enhancing visibility in low-light conditions.
- Interior Organization: Includes a spacious zippered main compartment, two mesh pockets, and a built-in key clip to help organize small gear efficiently.
- Versatile Attachment Points: Equipped with Duraflex brand hardware including side D-rings that allow you to securely attach water bottles, carabiners, or other accessories.
- Reflective Details: Reflective trim around the main zipper improves nighttime visibility, adding an extra layer of safety during dawn, dusk, or evening activities.

Benefits & Use Cases
The BackSak excels in environments where keeping gear dry is critical. Its IPX-6 rating provides robust defense against heavy rain, spray, and accidental submersion—such as falling into shallow water during river crossings or being drenched by ocean waves. This makes it ideal for hikers, campers, anglers, boaters, and commuters facing unpredictable weather. The ergonomic carry system ensures comfort even when fully loaded, making it suitable for multi-hour treks or daily urban travel. The external D-ring attachments offer convenient storage for water bottles or tools, while the interior organization keeps smaller items accessible yet secure. With multiple size options—25L for day trips and lighter loads, and 35L for longer excursions or bulkier equipment—the BackSak adapts to a wide range of needs. Even beyond outdoor use, its weather resistance and clean design make it a reliable choice for students, professionals, or anyone needing dependable protection for their belongings.
Important Notes
While rated IPX-6, this backpack is not designed for underwater use or prolonged immersion. It effectively shields contents from rain, splashes, and brief contact with water (up to approximately 1 meter depth for short durations). Always ensure the roll-top is fully closed and compressed before exposure to extreme conditions. Inspect seals regularly and re-roll the top securely after each use to maintain optimal waterproof performance. Note that laptop sleeves are not included standard but may be available as optional features in certain 35L variants. The product comes in various colors and two capacity options (25L and 35L), allowing you to choose based on your typical load requirements. For the highest level of water protection, consider the 35L premium model featuring an IPX-7-rated exterior pocket and additional organizational features.
Manufactured by Skog Å Kust, a family-owned company based in Pennsylvania since 2015, each BackSak reflects a commitment to functional design and all-weather reliability. Rooted in Swedish words meaning “Forest, Creek, Coast,” the brand emphasizes simplicity, durability, and practical innovation—crafting gear that performs when it matters most.
