The smell of a suitcase gradually builds up even when you use it on a daily basis.
First, let's summarize the most common causes.

- Moisture can cause mold and odors. If you do not dry the product thoroughly after use, moisture will remain in the interior and cause a moldy odor.

- Odors from clothing and shoes can easily transfer, such as the smell of sweat, damp shoes, and used clothing, which can easily become trapped inside a suitcase.

- Environmental odors from hotels and travelling: Room deodorizer, cigarette smoke, air conditioning smells, etc. may remain faintly on fabrics.

- Stuffy odor caused by long-term storage If you store it in a closet for a long time, the air won't circulate and it will develop a peculiar stuffy odor.

Leaving it for 6 to 24 hours will result in significant improvement.
Dried coffee grounds can also be used as a substitute.

ニオイが付きにくいスーツケースの選び方

Title

Suitcases vary greatly in how easily they retain odors depending on the material and interior lining.
It is especially important for those who travel frequently or who travel often on rainy days to choose a model that can be used comfortably for a long time.
Here we will summarize the points you should check when choosing a suitcase that is resistant to odors.

- Choose an interior material that absorbs moisture. Most suitcases have a polyester lining, but this has the drawback of trapping moisture.
On the other hand, materials like peach skin are moisture-absorbent and tend to prevent mold and odors.

It is hygienic and odors do not linger even after traveling.

- If there is a breathable mesh pocket or the inside is completely sealed, moisture will not escape and this will cause odor.
The breathable mesh pockets allow air to flow easily inside, keeping used clothing and small items from getting trapped.

-Is there a waterproof pocket for separating wet items? There are surprisingly many situations when you will need to store wet items while traveling, such as a folding umbrella, drinks, and skin care products.
Models with waterproof pockets will prevent moisture from spreading throughout the bag and prevent odors from transferring.

Overall, the most important thing is to choose materials and construction that do not retain moisture .
In that respect, the New Trip 1101 , which features a peach skin interior, mesh pockets, and waterproof pockets, is a model that is suitable for people who want to keep odors down while traveling and in storage.

Q1. スーツケースが臭うとき、まず何をすればいい？

A1：まずは乾燥です。スーツケースを開けて風通しの良い場所で30分〜1時間ほど換気し、内装に残った湿気や蒸れを逃がしてください。

Q2. 重曹はどれくらい置けば効果がある？

A2：6〜24時間を目安に置くと効果が出やすいです。小皿や布袋に入れて内装に直接触れないよう置き、状況に応じて一晩（24時間）置くと強い吸着効果が期待できます。
注意：重曹は直接布にかけないようにし、使用後は粉をよく払い落としてください。
