Best Dry Bag


Dry bags have a simple purpose: to keep water out of the interior of the bag. They typically use heavy-duty waterproof material, such as vinyl, PVC, nylon, or thermoplastic polyurethane (TPU), to do so. Put any items that you don’t want to get wet or damaged, including your phone, tablet, laptop, headphones, charger, food, clothing, or any other vulnerable gear, into your dry bag for safekeeping.

Waterproof protection makes a dry bag handy to have around the pool, but dry bags may be more useful while camping or boating. Use them when traveling to prevent a spilled drink from damaging passports, boarding passes, tickets, and other important documents.

What to Consider When Choosing the Best Dry Bag

Nothing spoils a trip faster than wet socks or a ruined phone. To avoid this and similar circumstances, choose a dry bag that’s not only water resistant but also an appropriate size with durable construction. So many dry bags are available that choosing one can quickly overwhelm the most determined shopper. When selecting the dry bag that’s right for you, first consider why you need one, followed by its size, fabrication, water resistance, storage, and ease of use.


One dry bag may suffice, but some excursions require two or more dry bags, each designed specifically for the activity. For instance, for a swimming or snorkeling trip, a standard dry bag won’t work; most dry bags cannot be fully submerged for extended periods.

Boating dry bags usually are more buoyant than standard dry bags, so if the boat capsizes or the bag is dropped, they float on the surface of the water. For camping, hiking, and climbing, consider a high-visibility dry bag that shows up clearly from a distance.


Size is determined by the capacity of the bag, which is usually measured in liters (L); sizes range from as small as 3L to more than 50L.

  • 3L to 10L dry bags hold phones, wallets, small tablets, communication equipment, or even a compass.
  • 10L to 30L dry bags, or medium, are good for cooking equipment, camp utensils, propane gas tanks, clothing, blankets, and other bulky gear.
  • 30L and larger dry bags are the largest options available, and they often come in  backpack or duffel bag form to pack more gear. Use them for first aid gear and emergency equipment, such as walkie-talkies or flares, to help ensure safety for everyone in the party.


Dry bags are typically made of vinyl, polyester, polyvinyl chloride (PVC), nylon, or TPU because these materials are tough and waterproof. Dry bag materials may be graded based on the density of the fibers, which is typically indicated with a number followed immediately by a “D.”

  • Vinyl and polyester dry bags aren’t as strong as PVC, nylon, or TPU, but they can hold small personal items like a phone, wallet, or keys.
  • PVC is the most durable material, so this type of bag may be better for boating or camping to protect the contents from abrasion damage as well as moisture.
  • Nylon dry bags are lightweight, durable, and waterproof. High-density nylon bags are stronger and more resistant to water.
  • TPU dry bags are rubbery and flexible, which makes them very durable and smooth. These bags offer a high level of water resistance, and some products can be submerged for an extended period of time with no damage to the contents of the bag.

Water Resistance

Water resistance is the primary reason most people use a dry bag. Light materials like vinyl and polyester aren’t suitable for submerging or even floating alongside a swimmer or a boat. Instead, these bags are better suited to protect electronics and other sensitive gear from rain, sleet, and snow.

High-quality dry bags are buoyant so they can float to the top of the water to be retrieved. However, if held under the water too long, even these bags may leak. For the highest degree of water resistance, look for a product capable of extended submersion.


When empty, most dry bags can be stored easily because they fold into a compact shape. However, when full or partially full, they’re more difficult to store. Some dry bags have additional features, such as a D-ring or loops, to help secure the bag.

Use a D-ring or carabiner to attach the bag to a motorcycle, RV, or boat. Similarly, lashing loops work well on moving vehicles, but they can also hang a bag at a campsite to keep the contents off the ground away from roaming animals.

Ease of Use

Ensure that the dry bag is the right size for the intended application. Along with a simple opening system, consider products with carrying straps, lashing loops, and D-rings. A typical dry bag uses a roll-top closure system, but some products have a zippered top.
