Keeps valuables dry in any environment. Whether you're camping, boating, fishing, or engaging in other escapades, every outdoor adventure presents the same dilemma: How to keep valuables and food close at hand while protecting them from the elements, especially water? At Ivation, we've got the answer in the bag. In a matter of seconds, you can seal your water-sensitive belongings in this watertight 'dry' bag without the need for any pumps or special tools. When properly inflated and sealed, it even floats on water. Highly Durable Lightweight design. The Ivation dry bag is made of abrasion-proof, puncture-proof, and tear-proof 500-denier waterproof polymer. This exceptionally tough and durable material never falters - even when put through the wildest weathers, water rapids, falls and scrapes. The polymer layers are constructed with high-frequency bonding technology, which ensures an absolutely watertight seal. Yet, while the bag is as tough as anything you can throw at it, it remains soft, flexible, pliable and easy to manipulate even in freezing temperatures. For carrying convenience, an extra-long, quick-detaching adjustable shoulder strap is included. The strap is strong enough to keep the bag attached to your body when you're swimming, whitewater rafting, and more. Reinforced construction at all stress points and a reinforced polymer buckle make this all the more reliable.
