Becko 20L Blue Dry Bag, Waterproof Case Pouch Include Shoulder Strap for Swimming, Surfing, Fishing, Boating, Skiing, Camping and Other Outdoor Sports, Protest Your Personal Item Against Water, Rain, Snow and Sweat (Blue, 20L) Becko dry bag is made of ultra tough non-rip water-resistant PVC tarp material with sealed seams and scrim-reinforced vinyl bottom. Easy to clean and convenient to carry. Roll the top of the dry sack down 2 to 3 or more times, fold the stiffener to squeeze the air out and clip the buckle together to keep the water away. Do make sure you roll it down at least 2 times before using. The adjustable and detachable strap is long enough (appliable length: 18-34 inches) to be slung over the shoulder or across the body. This dry sack can float when partially filled with air. It can be used as a lifesaving device when one falls into the water accidentally. Also perfectly protect your belongings against water, rain, splashes, mud and sand when you go sailing, kayaking, white water rafting, island hopping or camping. Light blue color perfectly shows your vigorous and unique personality. It makes the bag easy to spot and easy on the eye. The 20-liters sack is great for clothing, flip-flops, blankets, bottles and other larger items.
