Whether as a phone case, sports bag, or storage pouch, the waterproof pack sack Isar is well-suited for hiking, camping, outdoor tours, snowboarding, skiing, fishing, sailing, and beach outings. With its reinforced roll-top closure and high-frequency hot pressing, the bag offers optimal protection against rain and splashes, making it suitable for bike rides in summer as well as during the cold and wet seasons. The pack sack is highly durable, easy to clean, and practical to store. The waterproof storage bag comes with a shoulder strap and a D-ring for easy attachment. The bag is water-resistant but not 100% waterproof for full submersion. Therefore, the dry bag should not be submerged underwater, especially with valuables and electronic equipment inside.
