Before you buy
Common questions
What is the difference between water-resistant and waterproof backpacks?
Water-resistant backpacks can handle light rain or splashes but will let water in if submerged or in heavy rain for a long time. Waterproof backpacks, especially those with roll-top closures and sealed seams, prevent water from entering even when fully submerged for short periods.
Can I use a waterproof backpack for everyday hiking?
Yes, many waterproof backpacks are designed for hiking with comfortable straps and features like hip belts. However, they may lack organization pockets, so consider a hybrid model if you need quick access to smaller items.
Are roll-top backpacks really waterproof?
Roll-top closures are the most reliable waterproofing method when rolled correctly. They create a watertight seal, provided the fabric and seams are also waterproof. However, it is important to roll the top at least three times and clip it securely.
What is the best capacity for a day hiking backpack?
For day hikes, a 20 to 30 liter backpack is usually sufficient to carry water, snacks, an extra layer, and a small first aid kit. If you plan to carry fishing gear or a camera, consider a larger 30 to 40 liter pack.
How do I clean and maintain a waterproof backpack?
Rinse your backpack with fresh water after exposure to salt or dirt. Use a soft brush and mild soap if needed. Do not machine wash or dry. Reapply a waterproofing treatment to the fabric if water starts to soak in, but avoid the zippers and buckles.
Can a waterproof backpack be used for swimming or paddling?
Some fully submersible dry bags are designed for boating and can float with gear inside. However, check the manufacturer’s claims. Most dry bag backpacks can handle a dunking, but they may not float, so use a float bag if you are concerned about losing it.
Are there waterproof backpacks with comfortable suspension systems?
Yes, models like the Osprey Transporter and the Yeti Panga feature padded back panels and adjustable harnesses. However, they are heavier and may not be as streamlined as pure dry bags. Comfort is often a trade-off with weight.
What is the best way to pack a waterproof backpack?
Place delicate items like electronics in the middle, surrounded by soft gear. Roll your clothes to save space and reduce air pockets. Ensure that the roll-top is rolled down at least three times to create a tight seal. Do not overstuff the pack, as it may prevent a proper seal.
Can I use a waterproof backpack as a personal item on a plane?
Most waterproof backpacks in the 20 to 30 liter range meet airline personal item sizes, but always check with your airline. Some larger models may exceed dimensions. Since they lack a rigid frame, they can be compressed if needed.
What is the typical lifespan of a waterproof backpack?
With proper care, a high-quality waterproof backpack can last five to ten years or more. The seams and coating may degrade over time, especially with UV exposure. Store it away from direct sunlight and extreme heat to extend its life.
Our pick
For a combination of durability, comfort, and waterproof protection, the Sea to Summit Big River Dry Bag Backpack is the best choice for most car campers and hikers.
