Pro Tips: Watershed Drybags
Watershed Drybags are the GOAT when it comes to keeping your gear dry on whitewater trips. But let’s be real—these bags come with a slight learning curve. In this post, we’ll walk you through how to open and close them correctly, as well as basic care to keep them in top shape for seasons to come.

GOAT - Greatest of all Time
How to Open and Close a Watershed Drybag
To open the ZipDry closure, place your hands on or through the loops and form an “S” shape on the bag to release the seal. Avoid pulling the tabs straight out—it’s a common mistake that can damage the bag.
To close the bag, start at one end and pinch the seal shut while keeping a finger in the zipper track to help guide it. As you slide down the closure, push out any excess air. I like to use my knees to press the bag while zipping—it makes the job easier. Don’t overstuff the bag; you’ll need enough slack to fold the zipper over at least once for a solid seal. And don’t forget to clip the buckles to keep that fold locked in place!
Pro Tip: If you're letting a friend borrow your bag, make sure to show them how to open and close it correctly.
Watershed Maintenance
If you own a Watershed bag (or five!), do yourself a favor and pick up a bottle of 303 Aerospace Protectant. Think of it as sunscreen for your drybag—it keeps the ZipDry closure flexible and prevents sun damage.
You can find 303 online or at most auto parts stores.
How to Apply:
- Use a clean rag or paper towel.
- Soak it with 303 and work it into the zipper area.
- Open and close the zipper a few times to spread the protectant into all the nooks and crannies.
- If there’s extra on the rag, rub it on the exterior of the bag to help prevent fading.
You'll want to do this at a minimum at the start and end of every season, and even more if you live in a really dry climate.

Pro Tip: If you can’t get the last bit of sand out of the bottom of your bag, try using a handheld vacuum to suck it up!
Don’t Lose Your Gear
Watershed bags are the black rolly suitcase of the river world—everyone has one, and it is way too easy for someone else to grab yours by mistake. Label your bag with your name and contact info using a permanent marker, add a doodle or a No-So patch to make it stand out. Just remember: even "permanent" ink fades over time, so make refreshing it part of your yearly gear maintenance.
Pro Tip: Keep the zipper closed while your bag is in storage. It’ll help it last longer.
