Yes, when the HydroShield™ Magnetic Closure is fully closed - which means it's free of any debris or obstructions - your SideKick Dry® Gear Bag is 100% waterproof. Any obstruction or debris in the path of the magnetic closure will compromise its waterproof performance.
Always engage the hook and loop closure as an additional line of defense. You can help your SideKick Dry® Gear Bag continue to perform at its best by storing it completely clean and entirely free of debris and/or obstructions.
