Whether you're on a long hike and get caught in a downpour or you're enjoying a trip out on the water, it's a huge pain when your bag gets wet and your belongings soaked through. When you use a dry bag, you keep the offending water out and don't need to deal with a soggy sweater or wet sandwiches.
Our top pick, Earth Pak’s Waterproof Dry Bag, comes in various colors and has a secure, watertight closure.
Waterproof dry bags are made from either solid vinyl or heavy-duty nylon with a waterproof coating.
Vinyl (which includes PVC) is naturally waterproof and effective at keeping water out, plus it's thick and highly durable, although it can be heavy.
Nylon isn't naturally waterproof and therefore requires a waterproof coating. This is more accurately water-resistant and will wear away over the years. This type of dry bag is better if you just need splash or shower resistance rather than a bag that can keep water out even when submerged.
A dry bag's capacity is usually given in liters (L) and can range anywhere from 2L to 60L or more. Use 20L to 30L for day trips or single night trips (if you tend to pack light), as they fit a towel, a change of clothes, some snacks or a light meal and a few other basics. Larger 50L or 60L bags are best for multi-day trips or if you’re packing for the whole family.
Double-check whether your chosen dry bag is fully waterproof or simply water-resistant. Waterproof dry bags keep the contents totally dry, even if the bag gets soaked through, whereas water-resistant dry bags can only stand up to light rain showers or a handful of splashes.
Dry bags must have a certain type of closure in order to keep water out. This generally consists of a hook-and-loop strip or heavy-duty zipper across the top, which must be folded over several times, then secured up top with a plastic clip to keep it properly folded over. It's important to follow the closure directions carefully or your bag might not stay watertight.
Some dry bags have an exterior pocket or two to give your quicker access to items you might need regularly, such as your keys and wallet. Remember these pockets are usually only splash-proof or water-resistant, not fully waterproof.
Dry bags vary in price depending on size and overall quality and can cost anywhere from $10 to $100. The majority, however, retail between $25 and $50.
A. The vast majority of dry bags are unlined, so they won't protect fragile items from drops or knocks. If you're going out for a fast-paced day of water-based activities, it's best to leave any breakable items at home. However, if you must take something fragile with you on your travels, try wrapping it in a towel or sweater to offer some impact protection.
A. Dry bags are most commonly used by people engaging in water sports, such as kayaking or waterskiing, as you can take supplies with you without risking them getting wet if you bail out or your bag gets seriously splashed. They're also great for days at the beach or lake or for camping trips when there's a chance of rain.
