## Features

- Built to Endure: Featuring a reinforced multi-layer construction, this dry bag delivers exceptional tear and abrasion resistance yet remains flexible. Its ruggedness is backed by expertly welded seams, heavy-duty buckles, sturdy straps, and robust stitching. Designed to withstand rock scrapes and harsh conditions, it guarantees your gear stays protected and dry on every water adventure.
- Superior Waterproofing: The roll-top closure creates a watertight seal. Its round bottom helps you capture air quickly: simply spread the bottom open, roll the top down 3 to 5 times, and buckle. The trapped air blocks water and provides buoyancy. Keeps your gear dry in rapids, waves, snow, and sand. Designed for all common wet conditions but not for extended submersion.
- Multiple Sizes & Colors: A range from 5L to 40L suits any activity. 5L/10L are ideal for light trips and feature an adjustable, removable shoulder strap for cross-body carry. For heavier loads, 20L to 40L have backpack straps for even weight distribution, as a waterproof backpack. Every size folds into its own compact pouch. 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. Ideal for paddling, sailing, surfing, canoeing, or river tubing, as well as beach trips and water park outings. When rain rolls in, it also serves as a dependable waterproof bag for traveling, climbing, or hunting, keeping your gear dry no matter the weather.

## Questions & Answers

**Q: How many beers will the 20L hold in it? Also is the strap strong enough to hold this full of beers?**
A: The 20L is about 15 inches. If you did a nice circular stack with the cans you might be able to fit a little more than a 12 pack. Or do a circular stack and fill the middle with ice to keep them cold.😉

**Q: What are the dimensions on the 40L?**
A: 40L size is Height 16.9 x Bottom Diameter 11.9 inches after top is rolled 4 times.

**Q: How many pounds of kibble fits into 20L in these travel dog food bags?**
A: Depending on the dog food brand, a bit less than a 10 pound bag.

**Q: Family of 5 going on cruise,  spending day on beach. 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). I think my answer will be: "It depends" in how you define things for 5 people. I hope the fact that that same size bag carried a sleeping bag will help you with an idea of how thick it is. Do a Youtube search by writing "Marchway dry bag" and lots of info may pull to help you deeper. Have a good time.
