Dry bags: Which one would I choose? Differences that become clear when you think about how to pack your gear

Don't all dry bags look similar to you?
Just seeing the word "waterproof" wasn't enough for me to make a decision either.

If I were looking for a "dry bag," the first thing that comes to mind is the time spent packing before heading out to the beach or a campsite.
I spread out towels and a change of clothes on the floor, and while switching back and forth between product pages on my smartphone, I find myself hesitating, wondering if this is too big or, conversely, too small.
With things I don't want to get wet and things I'll be bringing back wet getting jumbled in my head, I think it's hard to decide just by looking at the sizes.

Perhaps the source of the hesitation isn't just whether it's waterproof or not.
It's about whether it fits the amount of gear I have, whether it's easy to carry, and whether I'll end up thinking, "This isn't how I intended to use it," after buying it.
In this article, to help resolve that hesitation, I will compare dry bags based on the situations in which they are used.

It's easier to choose a dry bag if you decide based on "what you don't want to get wet"

If it were me, the first thing I would look at, before capacity, is "what I want to protect."
Do you want to keep your change of clothes and towels all together, do you only need to protect small items like your wallet and smartphone, or do you want to separate large items like a wet tent?
Once this is decided, the necessary size and how to carry it become much clearer.

• If you are focusing on clothes and towels, a size around 10L to 20L is easy to use

• If you want to organize your gear into smaller portions, a set of multiple sizes is convenient

• If you want to bundle up wet, large gear, a high-capacity type is a candidate

• If you also want to protect your smartphone and wallet, a bag that comes with an attached pouch or a small bag is reassuring

In other words, even with the same dry bag, the roles they are suited for differ.
If you skip this and choose only based on price or appearance, you are likely to feel that "the things I want to put in don't fit" or "the way to carry it is different from what I imagined" after you buy it.

If I were looking at a classic shape first, the Unigear 10L would be an easy candidate to include

If I were choosing for the first time, I would look at the classic drum type first.
The reason is simple: it's easy to imagine using it even when you haven't narrowed down the use case to just one, such as for the beach, the pool, or camping.

The Unigear 10L is a roll-top type where you fold the opening and fasten the buckle.
It is a waterproof specification using PVC material, and it comes in sizes from 2L to 40L, with the 10L size being easy to think of for purposes like bundling clothes and towels.
Moreover, it comes with a strap, making it easy to use as a shoulder bag or a handbag, and it also includes a smartphone case.

What makes me feel at ease looking at this type is that it's hard to go wrong with the usage scenario, even for someone who just thinks, "I want to have one just in case."
Since it is made to be easy to use not only for the beach and rivers but also for touring, camping, and hot springs, I think it is easy to adapt to for people whose intended use is still a bit vague.

Conversely, for people who want to carry things as lightly and compactly as possible, or for those who want to organize their gear in detail, the direction might be a little different.
The included smartphone case is convenient, but it does not support Touch ID or operation of the pouch from the outside while underwater, so if you are expecting that kind of usage, you should check that beforehand.

If I were someone who wanted to pack gear separately, the BeeNesting 3-piece set would be easy to understand

Here, I will imagine myself just before buying.
For example, while preparing for a trip or camping, if you have small items like a change of clothes, rain gear, and gloves lined up next to your bag, you might feel that "it's hard to take things out if I put everything in one bag."
In such cases, a set type where you can get different sizes at once can be easier to use later.

BeeNesting is a 3-piece set of 2L, 4L, and 8L.
It uses semi-transparent material to make it easy to check the contents, and it has a cylindrical shape that makes it easy to pack.
It uses silicone-treated ripstop nylon, and a feature is that it is quite light, totaling about 90g for all three sizes.

For me, I choose this product not as a main, large bag, but for how easy it makes organizing my gear.
Since I can separate items—small things in the 2L, jackets and gloves in the 4L, and a change of clothes in the 8L—it prevents things from getting cluttered when I'm packing.
Plus, because it's translucent, it's helpful to be able to see what's inside before opening it.

On the other hand, it's a bit different for someone looking for a large dry bag to carry around on their shoulder as a standalone bag.
Since its primary purpose is closer to "organizing storage," someone who wants to throw their towel, sandals, and everything else together for the beach would likely find a different type of bag around 20L easier to imagine using.

If I'm thinking about packing up after a trip, Coleman's large-capacity bag has a very clear role

When looking for a dry bag, I tend to look at it with the assumption that I'll be putting my everyday change of clothes or a towel in it.
But sometimes I realize later, "Oh right, I wanted to separate my wet items to bring them home."
If you overlook this, you tend to choose a size that's too small and end up running out of space.

Coleman's outdoor dry bag is a large-capacity type with a volume of about 110L.
It features a shoulder strap and makes it easy to store large items, like a wet tent flysheet, separately from other gear.
The opening can be rolled up, which is a shape that makes it easy to adjust the capacity while preventing water from getting in.

I consider this one when I'm concerned about my gear after packing up from camping or touring.
For those who want to avoid having wet sheets or clothing dampen their other belongings on the way home, its role is very clear.

On the other hand, it might be too big for someone who just wants to put in a change of clothes and small items for a day trip.
While the 110L size is reliable, I feel it's aimed at people with a specific purpose rather than something to use casually as a first bag.

If I'm thinking about everyday use as well, Spigen's 20L + 2L set is easy to use for different purposes

Another thing I struggle with is whether to make it "exclusively for leisure or in a shape I can use every day."
It's hard to pull the trigger on buying something you'll only use occasionally, right?
That's why I look to see if I can imagine using it for everyday life, not just for outdoor activities.

Spigen is a set that includes a 20L dry bag and a 2L small bag, and it claims IPX6-certified waterproof performance.
It features adjustable straps, making it easy to change how you carry it, such as as a backpack or a shoulder bag.
It's easy to put clothes, towels, camping gear, or food in the 20L bag, and small items can be separated into the 2L side.

I think the strength of this set is that the division of roles is clear.
Main gear in the large one, valuables like your smartphone and wallet in the small one.
For people who are bothered by small items getting lost inside a single bag, this way of separating things should feel just right.

Conversely, if you're someone who prioritizes lightness above all else for hiking or backpacking, an ultra-lightweight type like BeeNesting might be a better fit.
Spigen's appeal is its versatility, so it's a bit different from choosing based solely on lightweight performance.

How I would choose: 4 crossroads to reduce hesitation when picking a dry bag

Looking at it this way, I feel that when choosing a dry bag, it's easier to be satisfied if you decide based on "what you don't want to be troubled by" rather than "which one is the best."

• If you want a versatile first bag, look for a standard 10L model.

• If you want to organize the inside of your bag, a lightweight set of multiple sizes is convenient.

• If you want to bundle up large, wet gear, a high-capacity type is reliable.

• If you want to separate your change of clothes from your valuables, a set consisting of a main bag plus a smaller bag is easy to use.

The ones you are least likely to regret buying are those where you can clearly visualize how you will pack your gear.
For example, if you only need to pack a towel and a change of clothes, 10L to 20L might be enough, but if you want to fit your tent and other gear after breaking camp, you will need something in the 110L class.
If this matches your needs, it becomes easier to justify the price difference.

Summary | If I were stuck while packing, I would choose based on these criteria

If you find yourself staring at your phone and unable to start packing, the shortcut is to first decide 'what you don't want to get wet' and 'how much you want to pack together'.

If it were me, I would choose Unigear if I wanted a versatile first bag, BeeNesting if I wanted to organize things lightly, Coleman if I were thinking about packing up after camp, and Spigen if I wanted to use them differently depending on how I carry them daily.
Conversely, if those conditions don't apply, there is no need to rush; it is not too late to reconsider the capacity and purpose.

To ease that hesitation before packing even a little, try looking at the type that is closest to your own situation.
