What kind of shoulder bag, recommended by a leather brand employee, can fit a 500ml plastic bottle?

We often buy 500ml plastic bottles when we're out and about.
“I bought it, but carrying it around is a hassle…”
“It doesn't fit in my bag, so I have to carry it by hand…”
Many of you have probably had these experiences, right?
If you have a shoulder bag that can fit a plastic bottle, you can go out more comfortably.
In this article, we will explain the conditions and how to choose a shoulder bag that can fit a 500ml plastic bottle.
In the latter half, we also introduce shoulder bags recommended by bag designers, so please refer to them.
Conditions and How to Choose a Shoulder Bag that Can Fit a 500ml Plastic Bottle

Even if you want a shoulder bag that can fit a 500ml plastic bottle, it's difficult to actually put it in the bag and try it out, right?
So, we've summarized the conditions and how to choose a shoulder bag that can fit a 500ml plastic bottle.
-
Height or width of 25cm or more
-
Material that does not bulge even when storing a plastic bottle
-
Whether there is a pocket inside the bag
-
Shoulder strap width and cushioning
By keeping these points in mind, you will be able to identify a shoulder bag that can comfortably store a plastic bottle.
1. Height or Width of 25cm or More
A shoulder bag that can fit a 500ml plastic bottle must have a height or width of 25cm or more.
The general size of a plastic bottle is as follows:
| Volume | Height | Diameter |
|---|---|---|
| 280ml | Approx. 16cm | Approx. 6cm |
| 350ml | Approx. 17cm | Approx. 6cm |
| 500ml | Approx. 21cm | Approx. 7cm |
The typical height of a plastic bottle is about 21cm.
Considering the width of the zipper, a size with about a 5cm margin (25cm or more) is ideal. 
Also, pay attention to the depth.
Since the diameter of a plastic bottle is about 7cm, it's safer to choose a bag with a depth of 8cm or more.

25cm is almost the same size as an iPad.
If a shoulder bag can fit an iPad, it should have no problem fitting a 500ml plastic bottle.

2. Material that doesn't bulge when storing a plastic bottle
To prevent the part where the plastic bottle is placed from bulging, you also need to pay attention to the material.
Bags made of soft materials such as nylon or cloth tend to bulge or lose their shape when a plastic bottle is placed inside, which can make them look unseemly.
Bags made of durable leather material are able to maintain their shape and a firm silhouette even with a plastic bottle inside.

Even with leather, soft leather can easily lose its shape, so be careful.

3. Presence or absence of internal pockets in the bag
The presence of pockets inside the bag is also an important condition.
Plastic bottles tend to condensate, and there is a possibility that water droplets may wet the inside of the bag.
Therefore, it is important to choose a shoulder bag with internal pockets that can separate items you don't want to get wet, such as books, notebooks, and smartphones, from the plastic bottle.

It's convenient to have a large pocket, especially for paper items like books that you really don't want to get wet.

4. Shoulder strap width and cushioning
The shoulder strap, which is often overlooked, is also an important point when choosing a bag.
A 500ml plastic bottle has a certain weight, and carrying it can put a strain on your shoulder.
Thin straps, in particular, tend to dig into the shoulder, so it is recommended to choose a wide strap.
Also, a type with a padded cushion on the shoulder area will make it even more comfortable to carry.

For shoulder straps, a width of 3cm or more is recommended.
