Step-by-Step Guide to Getting Air Out of Your Dry Bag

If you want to get air out of your dry bag, pack your gear, press down to squeeze out extra air, then roll the top tightly before sealing. This step keeps your items dry and saves space in your pack. Check out how much space you can save:

Many people make mistakes like not rolling the top at least three times, overpacking, or missing small holes. Always double-check the seal to keep your gear safe.

Key Takeaways

• Pack your dry bag with soft items like clothes and sleeping bags. This helps you squeeze out air easily.
• Always roll the top of your dry bag at least three times before sealing. This creates a tight seal and keeps your gear dry.
• Leave 2-3 inches of space at the top of your bag. This space is crucial for rolling and sealing properly.
• Check the seal by pressing on the bag or submerging it in water. Look for bubbles to ensure it is airtight.
• Use silica gel packets inside your bag to absorb moisture and keep your gear fresh.

Remove Air from Dry Bag

Pack Your Gear

Start by choosing the right gear for your dry bag. You want to pack items that fit well and allow you to squeeze out air easily. Soft gear like sleeping bags, clothes, and towels work best. Hard items can make it tough to get a tight seal and may even damage the bag over time.

Here’s a quick look at how different valves help with packing and air removal:

If you’re heading out for water sports, you might pack your dry bag inside a bigger backpack. For hiking, you can use smaller ditty bags inside your dry bag to keep things organized and light. Always check your gear before packing to make sure it’s dry and clean.

Squeeze Out Excess Air

Once your gear is inside, it’s time to get rid of the extra air. Fill your dry bag about two-thirds full. This gives you enough room to roll the top and squeeze out air. Line up the edges of the opening. Press down on the bag with your hands or forearms. As you roll the top, keep pressing to push out as much air as possible.

Tip: Squeezing out air creates a vacuum seal. This keeps your gear dry and helps your bag pack down smaller. It also stops your bag from floating away if it falls in the water.

Here are some techniques you can use:

• Roll the top tightly 3–4 times while pressing out air.
• Use your body weight to help compress the bag.
• If your dry bag has a one-way air valve, open it while rolling to let air escape faster.

Some dry bags, like eVAC models, can puff up on their own. You’ll need to press and roll them to get all the air out. Softer items are easier to compress, while hard gear might make air removal tricky.

Roll and Seal the Top

Now you’re ready to seal your dry bag. Rolling the top is the most effective way to keep air out and water away from your gear. Here’s how you do it:

1. Align the edges of the opening.
2. Roll the top down at least three times. Each roll pushes out more air and tightens the seal.
3. Clip the buckles together to lock the closure.

Check out how different closure methods compare:

Roll-top closures work best for removing air and keeping water out. Zip-lock closures give you quick access but may not seal out air as well.

Note: If you find a puncture or hole in your dry bag, don’t risk your gear. Here’s what you should do:

1. Inspect the damage.
2. Clean the area with isopropyl alcohol.
3. Cut a patch at least one inch bigger than the hole.
4. Apply adhesive to the patch and the area around the hole.
5. Press the patch down and hold it in place until it cures.
6. Fill the bag with water to test for leaks.

Vacuum sealing works by removing air and oxygen from the bag before sealing. This keeps your gear dry, reduces the size of your packed items, and helps prevent bacteria growth if you’re storing food.

Packing your dry bag the right way makes your adventures safer and more comfortable. You’ll have more space, less weight, and peace of mind knowing your gear is protected.

Tips and Mistakes

Avoid Overfilling

You might feel tempted to stuff your dry bag to the brim, but leaving space at the top is key. When you overfill, you make it hard to roll the top down and squeeze out air. This can strain the seams and seals, which may cause leaks or even damage the bag. Always leave about 2–3 inches of space at the top. This space lets you roll the top down tightly and create a good seal. If you fill the bag past its recommended capacity, you risk uneven seals and possible breakage. Remember, a little extra room goes a long way in keeping your gear safe and dry.

Best practices for packing:

1. Pack only what you need.
2. Leave enough space at the top for sealing.
3. Never force the bag closed if it feels too full.

Check the Seal

A good seal keeps water out and air from sneaking back in. After you pack and roll the top, always check the seal before you head out. You can use a few simple methods:

• Try the immersion method. Submerge the bag in water and watch for bubbles. If you see any, air is escaping and you need to reseal.
• Use your hands to press on the bag and listen for hissing sounds.
• For extra peace of mind, some people use netting or even a vacuum sealer to remove air and check the seal.

Tip: Always roll the top at least three times and clip the buckles. This step helps you get the tightest seal possible.

Prevent Moisture Inside

Even if you seal your bag well, moisture can still sneak in. Common mistakes include packing wet gear, letting condensation build up, or placing the bag on soggy ground. Sometimes, sharp objects or animal activity can cause tiny holes that let water in. To keep things dry:

• Pack only dry items.
• Add a silica gel pack to absorb any moisture.
• Avoid placing your bag on wet or uneven ground.
• Check for punctures or tears before every trip.

If you follow these tips, you will keep your gear dry and your adventures worry-free.

Why Air Removal Matters

Waterproofing

When you remove air from your dry bag, you do more than just save space. You help keep your gear safe from water. Air pockets can trap moisture inside. This moisture can lead to mold and mildew, which can ruin your gear and make your bag smell bad. You want to avoid that, right?

Here are some tips outdoor pros use to keep their bags waterproof and fresh:

• Always air-dry your bag in a shaded, well-ventilated area. Direct sunlight can damage the waterproof coating.
• Dry your bag upside down. This helps any trapped water escape.
• Make sure your bag is completely dry before you store it. Even a little moisture can cause musty odors or mold.
• Good ventilation is key. It stops mold from growing and keeps your bag ready for your next trip.

Note: Mold and mildew not only smell bad, but they can also break down the waterproof layer of your bag. Take a few minutes to dry your bag well after every adventure.

Packing Efficiency

Getting the air out of your bag makes packing much easier. When you squeeze out the air, your bag shrinks down. This gives you more room in your backpack or kayak. You can fit more gear or just enjoy a lighter load.

Let’s look at how air removal helps you pack smarter:

• Your bag takes up less space, so you can organize your gear better.
• You avoid bulky, awkward shapes that make packing hard.
• A tightly packed bag is easier to carry and less likely to shift around.

If you plan to carry your bag for a long hike or paddle, you will notice the difference right away. Your gear stays compact and protected. You spend less time fighting with your pack and more time enjoying the outdoors.

Troubleshooting Dry Bag Issues

Stubborn Air Pockets

Sometimes, no matter how hard you try, you still find air trapped inside your dry bag. These stubborn air pockets can make your bag bulky and less waterproof. You want to get rid of as much air as possible for the best results. Here are some simple steps you can follow:

• Make sure your gear, like clothes or sleeping bags, touches the inside of the bag as much as possible. Try to get at least 75-80% contact. This helps push out air and keeps things tight.
• If you notice big gaps or your gear pulls away from the bag, take everything out and repack. Try to keep your items moist if you are packing food, like meat, so they stick better to the bag.
• Sometimes, small air pockets are hard to avoid. If your bag looks like a balloon, you may need to reseal it or use a new bag.
• If you trimmed your bag too close to your gear, switch to a new one for a better seal.

Tip: Press down on your bag as you roll the top. Use your knees or elbows for extra pressure. This helps squeeze out stubborn air.

Packing Electronics

Electronics need extra care when you pack them in a dry bag. You want to keep out both air and moisture to protect your devices. Here are some methods you can use:

• Use a vacuum sealer if you have one. It pulls out air and keeps your electronics snug.
• Add silica gel packets to soak up any leftover moisture. You can also toss in a hand-warmer to help reduce oxygen.
• If you use inert gases, seal the bag right away so air does not sneak back in.

Note: Always double-bag your electronics for extra safety. Place them in a smaller waterproof pouch before putting them in your main dry bag.

You can keep your gear safe and dry by following a few simple steps. Pack your items, squeeze out extra air, roll the top tightly, and seal the bag. Here’s what studies show helps most:

• Removing air boosts waterproofing and stops leaks.
• Tight seals keep water out.
• Strong materials and sealed seams protect your gear.
