Keep Gear Bone Dry: Top Backpacking Dry Bags Compared
The Sea to Summit eVent Compression Dry Sack is our top pick for backpackers who need to compress bulky gear like sleeping bags and puffy jackets. It uses an eVent fabric that lets air escape during compression while staying completely waterproof, saving up to 50% volume. The main limitation is its higher price compared to simple stuff sacks, but for multi-day trips where space is critical, it’s worth the investment.
Nothing ruins a backpacking trip like a soaked sleeping bag. A reliable dry bag is your first line of defense against rain, river crossings, and accidental drops. But not all dry bags are equal. Some are ultralight, some are bombproof, and some double as compression sacks to shrink your load.

Whether you need a simple dry sack for clothes or a compression sack for your sleeping bag, we’ve got you covered.

Frequently asked questions
Are dry bags truly waterproof?
Yes, most dry bags with a roll-top closure and taped or welded seams are waterproof when sealed correctly. They can be submerged for a short time. However, prolonged submersion may allow water to seep in if the seal is not perfect. For guaranteed submersion, choose a bag with a waterproof zipper or a higher IP rating.
How do I roll a dry bag correctly?
Place your gear inside, then press out excess air. Fold the top of the bag down about three to five times, making sure each fold is tight. Then clip the sides together. The more folds you make, the more secure the seal. Ensure the strap is snug but not overly tight to avoid stressing the fabric.
What size dry bag do I need for a sleeping bag?
A standard mummy sleeping bag usually fits in a 20 to 30 liter dry bag. If you want to compress it, choose a compression dry sack in a similar volume. For a two-person tent, consider a 30 to 50 liter bag. Measure your gear and leave some extra space for easy packing.
Can dry bags be used for electronics?
Yes, dry bags are great for protecting electronics from water. However, to be safe, place electronics in a ziplock bag or a dedicated waterproof case inside the dry bag. This offers double protection, especially if the dry bag is accidentally punctured. Also, avoid exposing electronics to extreme compression.
How do I know if a dry bag is submersible?
Check the product specifications. Bags with a roll-top closure are generally not designed for extended submersion, but they can handle brief immersion. Bags with waterproof zippers and heavy-duty materials, like the YETI Panga, are often rated as fully submersible. Look for terms like ‘submersible’ or ‘IPX8’.
What is the difference between a dry bag and a stuff sack?
A dry bag is waterproof, while a stuff sack is typically water-resistant but not fully waterproof. Stuff sacks are often made of lightweight nylon and are not sealed. Dry bags use roll-top closures and welded seams to prevent water entry. For backpacking, a dry bag is essential if you need to keep gear dry.
Are expensive dry bags worth it?
Expensive dry bags often use higher quality materials, better construction, and are more durable. They may also have compression features. If you backpack frequently or in wet conditions, investing in a quality bag is wise. For occasional use, a budget option may suffice, but remember that a failed dry bag can ruin your trip.
Can I use a dry bag for kayaking or rafting?
Yes, dry bags are commonly used for water sports. For kayaking, you might want a bag that can be strapped to the deck. Look for bags with lash points or D-ring attachments. For rafting, larger bags are available. Ensure the bag is fully waterproof and has a secure closure.
How should I clean my dry bag?
Use mild soap and water. Avoid abrasive cleaners. Rinse thoroughly and air dry. Do not put it in a washing machine or dryer. For stubborn stains, use a soft brush. Keep the buckles and zippers free of sand and dirt to maintain functionality.
What is the best way to pack a dry bag in a backpack?
Place heavy items at the bottom of your backpack, but keep your dry bag accessible. Roll the dry bag tightly to minimize air and space. Put it vertically or horizontally depending on your pack shape. For compression sacks, compress before placing in your pack to save space.
Final word
For most backpackers, the Sea to Summit eVent Compression Dry Sack is the clear winner because it combines waterproofing with compression, saving critical space in your pack. If you prioritize ultralight weight and don’t need compression, the Sea to Summit Ultra-Sil Dry Sack is the best choice. For those who expect heavy submersion or rough conditions, the YETI Panga offers unbeatable durability. No matter which you pick, ensure you roll it correctly and maintain it well, and your gear will stay dry.
