The Importance of Closing a Dry Bag Correctly.  

A roll-top dry bag only remains waterproof if closed properly.  

Follow these three simple steps to make sure your bag is sealed: 

1. Flatten the Top Edge.  

Align the top opening so both sides line up evenly. Squeeze out excess air from the main compartment, or leave a small cushion of air if you want the bag to float. 

2. Roll Tightly Downward. 

Fold the top edge downward tightly over itself. Make at least 3 to 4 rolls to create a watertight barrier. Rolling less than three times can risk water soaking through under pressure. 

3. Buckle in Reverse. 

Bring the two buckle ends together, roll them around before bending them toward the side opposite your folds, and snap the buckle shut. This tension keeps the rolls tight and creates a top handle for quick carrying. 

To Sum It Up.  

A dry bag is an essential, multi-use bag for water sports, rainy travel, and internal organization. Whether you're protecting your tech or separating laundry from your fresh clothes, staying dry comes down to a proper seal. Roll the top tightly at least 3 to 4 times before snapping the buckle.  

Treat your bag right with gentle hand-washing, and it will keep your gear safe, organized, and dry for years of adventures. 

Frequently Asked Questions. 

Is a dry bag the same as a wet bag? 

No. A dry bag is designed to keep water out to protect your gear from getting wet, while a wet bag is designed to keep moisture and dirt in so damp or dirty items don't ruin the rest of your belongings. While they are designed to solve different problems, many modern bags are built with water-resistant materials capable of doing both.  

Can I put wet clothes in a dry bag? 

Yes, you can put wet clothes in a dry bag. However, to prevent leaks and protect your gear fully, you should always remove excess water that can seep out through the roll-top seal or seams.  

Do dry bags float? 

Yes, most dry bags float when they are sealed correctly with trapped air inside. When rolling the top down at least 3 to 4 times, the bag can act as an air pocket, keeping your gear floating on the surface if it is dropped overboard – depending on the weight of its contents.  

Can a dry bag be washed? 

Yes, dry bags can be washed by hand using warm water and a mild soap. You should never put a dry bag in a washing machine or dryer, as doing so will ruin the membrane and seam tape.

Simply wipe it down inside and out with a soft sponge or cloth, rinse, and hang it upside down to air dry completely before storing.
