Choose from classic darks to vibrant brights to match your style. - Stays Afloat & Secure: When properly sealed and not overloaded, the dry sack floats visibly on the water, making your gear easy to spot and quick to retrieve. A reinforced D-ring and strap let you fasten the bag to your boat or kayak, keeping your belongings secure and within reach, so you can fully embrace the thrill of the outdoors. - Versatile Utility: Engineered for rugged durability and reliable waterproof protection, this bag is essential for any aquatic adventure.

What size would be best to carry everyones things? Do i need to 2?** A: The biggest is the 40L, I carried a cozy thick coleman sleeping bag (that is all).
