How to Pack a Dry Bag for a Day on the Water

Quick Answer

To pack a dry bag for a day on the water, roll your gear tightly, place heavy items at the bottom, and seal the roll top with at least three folds to keep everything dry.

How to Pack Your Dry Bag in 5 Steps

1. Step 1: Gather and Roll Your Gear: Lay out everything you plan to bring. Roll clothing and soft items tightly to remove air and save space. For electronics, place them in a small waterproof pouch or zip-lock bag before putting them in the dry bag. Check that no sharp objects like keys or tools are left loose—they can puncture the bag from the inside.
2. Step 2: Pack Heavy Items at the Bottom: Place heavier items like a water bottle, camp stove, or shoes at the bottom of the bag. This keeps the bag stable and prevents lighter items from being crushed. Avoid putting sharp objects at the bottom where they might press against the seam. If you have a backpack-style dry bag, pack heavy items close to your back for better balance.
3. Step 3: Fill the Bag to About 75% Capacity: Leave some empty space at the top. Overfilling makes the roll top hard to close and can cause the seal to fail. Under-filling leaves too much air, which makes the bag float awkwardly and can put stress on the closure. A good rule of thumb: you should be able to fold the top over at least three times before clipping it.
4. Step 4: Seal the Roll Top Properly: Fold the top of the bag down toward the main body, then roll it at least three times. Make sure the roll is tight and even. Clip the buckle or close the velcro securely. The roll should be perpendicular to the bag's opening to prevent water from seeping in. Test the seal by turning the bag upside down for a few seconds—no water should enter.
5. Step 5: Secure the Bag for Transport: Use the shoulder strap or handle to carry the bag. If you're on a kayak, attach the bag to the deck or inside a hatch with a carabiner or bungee cord. Keep the bag out of direct sunlight for extended periods to prevent material degradation. When not in use, store the dry bag open and dry to prevent mold and mildew.
