While it’s protecting your gear from dirt, mud, and snow, the exterior material won’t crack or go stiff.

Not everyone needs a large dry bag. And the reality is that for some people, even a five-liter bag might be a little on the big side. The Unigear Waterproof Dry Bag is the perfect solution for the person who wants to protect a few items from the elements, but doesn’t want to lug around a large bag all day. We like that this roll-down dry bag offers the smallest capacity in our guide — two liters. But in total, they have six capacities: two, five, 10, 20, 30, and 40 liters.

Storage is important when you’re eyeing a dry bag for your outdoor activities.

We selected the Piscifun Waterproof Dry Bag Backpack because it’s the only option in our guide to include an exterior storage component.

First, we like that this is a set of dry bags, ranging in two, four, and eight liters. While these bags aren’t made from polyester and lack the accessories seen on all of the other bags in our guide, we think that budget-conscious shoppers will like the value of getting three bags for the price of what one would cost with any of the competitors in our guide.

Note: Other waterproof backpacks worth mentioning here that are not on our list include the Watershed Colorado Duffel Drybag, the Big River Dry Bag by Sea to Summit, as well as the eVent Compression dry sack, and the YETI Panga 75 Dry Duffel.

How We Decided

Waterproof bags (also known as dry bags) are essential if you’re trying to keep your valuables and gear dry while you’re in or near the water. To create our guide, we considered the following features — waterproof, materials, durability, size, ease of use, and additional features.

Not all dry bags are equally waterproof. As we found in our research, “waterproof” doesn’t mean the same thing for every manufacturer, and it’s the most important factor that you need to consider before purchasing this item. Even though every product we reviewed claims to be waterproof, all the options were only water-resistant instead of being rated as safe against sustained submersion.

Next we looked at the dry bag size options. Most dry bag brands came in a range from four to six sizes. If you’re focused on finding the smallest dry bag possible, we recommend the Best Budget since it’s the only one that offers a two-liter option. In contrast, most other brands start with either a five or 10-liter dry bag. However, if you want a large dry bag, the largest was the 55-liter bag from our #3 pick.

Materials are also critical for selecting a dry bag. Through our research, we noted that the two most common options included a coated nylon or a 500D PVC. PVC is great for resisting rips and tears that would commonly occur if you’re dragging a bag like this over rough terrain. But we also looked at how those materials made a bag easier to use. Specifically, our Honorable Mention and #6 picks excelled in this category. Both of them offer either a see through panel or an entirely see-through design — making the process of quickly grabbing something out of your bag significantly easier.

And in terms of additional accessories, one of the most common options we saw were the waterproof smartphone cases. While you need to confirm that the smartphone case is compatible with the size of your phone, this is a nice value-added feature to look for in a quality dry bag.

Best Waterproof Bag Buyer’s Guide

The Most Important Factors to Consider

  1. Waterproof
    Waterproof bags are also known as dry bags, so don’t be surprised if you see that language when you shop for one. But obviously, the most important feature is water resistance. Dry bags are designed to keep their contents from getting wet. But there’s a range of water resistance so you’ll need to keep this in mind as you look for the right option for your needs. Some waterproof bags can be submerged underwater for long periods, while others can only handle an occasional splash or wave. Always check the waterproof claims to confirm that it’s compatible with your intended activities.
  2. Materials
    A good dry bag will usually be durable, flexible, and lightweight. A durable dry bag can hold up to consistent use even in rough terrain.

    • A lightweight dry bag won’t add to your load — especially if you’re biking or hiking. And flexible dry bags can accommodate unexpected capacities without damaging the exterior.
    • These types of bags are usually made from vinyl, nylon, PVC, and TPU.
    • Alternatively, leather messenger bags for men are also available, but they tend to be heavier and more expensive.
  3. Size
    How large do you want your dry bag to be? This is going to depend on what you plan on packing and how long you plan to use your bag in one trip. An afternoon hike won’t require a large-capacity bag, whereas a multi-day camping adventure would. Also, think about how you’ll be carrying this waterproof bag. If you’re hiking or biking, a lightweight bag is the best bet to minimize the risk of excess weight.
  4. Durability
    Technically durability goes hand in hand with the materials factor. But you’ll want to look at bags that offer double stitching or carrying straps. These features make it easier to secure your bag and to withstand coming into contact with rough surfaces.
  5. Closure Options
    There are two common options for waterproof bags — roll tops and zippers. Depending on your needs, one option might be better than others. However in general, if you’re planning on spending time around the water, experts agree that a roll-top has better water resistance and is more secure than a zipper closure.
  6. Additional Features
    The importance of additional features is going to depend on what’s a priority for you. But we looked at models that offered options such as additional interior pockets or included additional waterproof smartphone cases so that you didn’t need to leave your phone in your waterproof bag to keep it safe. Likewise, an option like a viewing window is nice when you’re trying to take one specific item out of your bag.

Waterproof Bag FAQs

Are dry bags really waterproof?

Yes, but the level of water resistance is going to vary between dry bags. It can range from extended submersion to basic water-resistance from rain or a splash of water. If you’re spending a lot of time in the water (such as rafting), then you’ll want extended submersion.

Can you swim with a dry bag?

If a dry bag is rated as being waterproof against extended submersion, then yes. However, you always need to check the waterproof rating as some are designed only to protect the contents inside the bag from light water exposure.

What is the best dry bag?

The best dry bag is the one that is easiest for you to use, offers the capacity that you need, and is less likely to crack or fall apart in extreme weather. In our guide, we nominated the KastKings Dry Bag as our Top Pick because of the large viewing window that makes it easy to find items when you need them, and the range of capacities from 10 to 30 liters.
