FAQ (Frequently Asked Questions)

一、 3泊4日の荷物、どれくらいのサイズが正解？

When choosing the perfect suitcase for a four-day, three-night trip, the first thing to consider is capacity . On short trips, it's important to keep the amount of luggage you carry to a minimum, so choosing a size that allows you to store everything efficiently is the first step to a comfortable trip.

■【機内持ち込み派】vs【預け入れ派】のメリット・デメリット

Generally, the ideal suitcase capacity for a three-night, four-day trip is around 40L to 60L . This capacity range will allow you to store all the essentials for your trip, such as clothes, cosmetics, and shoes, and still have ample room to organize them. However, the optimal capacity will vary depending on the season of your trip and the amount of luggage you will be carrying , so it's important to choose a suitcase that suits the season.

■ 季節やお土産の量で変わる「40L〜60L」の選び分け

・For summer (light clothing) : We recommend a suitcase of around 40L . On summer trips, you'll be mainly carrying light clothing, so you won't need to carry much luggage. This size is especially suitable for domestic trips or trips to resorts. For example, four T-shirts, two pairs of shorts, underwear, shoes, etc.

For winter (heavy clothing) : If you're traveling in winter, we recommend a 50L to 60L capacity. Thick clothing like sweaters and coats are bulky, so you'll need a larger size. This size will allow you to easily store your winter clothes, coats, shoes, and cosmetics.

If you expect to bring more souvenirs or additional luggage during your trip , choose a suitcase with an expandable compartment . The expandable compartment can increase capacity by up to 20%, so you can accommodate any extra luggage you bring on the way home.

二、 女性がチェックしたい「移動をラクにする」4つのポイント

A suitcase is more than just a tool for carrying luggage; it greatly affects the comfort of your trip. For women in particular, design, lightness, and functionality are important points when choosing a suitcase. Here are six key points that women should pay attention to when choosing a suitcase.

■ 軽さ：階段や棚への上げ下げを考慮した「3kg以下」

For women, a suitcase with an attractive design that lifts your spirits from the very start of preparing for a trip is extremely important . If the color and texture match your style, traveling will feel even more enjoyable. Whether it's a pastel color, a simple and elegant design, or something with a gorgeous sheen, choosing a suitcase that looks appealing will boost your motivation for the entire trip.

■ 静音・ストッパー：電車移動や夜道のストレスをゼロに

Good casters and handles are essential for smooth mobility. 360-degree rotating double casters allow for smooth maneuvering even in tight spaces and easy changes of direction. Choosing quiet casters also allows for comfortable movement without worrying about noise, even during early morning or late-night moves. Furthermore, a multi-stage carry bar that can be adjusted to suit your height reduces strain on your arms and makes carrying it easier.

■ フロントオープン：移動中の「ちょっと出し」をスマートに

Even on a four-day, three-night trip, you may end up with a surprising amount of luggage. To efficiently store your clothes, cosmetics, accessories, and more, it's important to have a bag with ample storage capacity and an interior that's easy to organize.

Choosing a suitcase with dividers and pockets that allow you to organize your luggage, such as U-shaped compartments, mesh pockets, and X-shaped fixing bands, will make it easier to take out your luggage while traveling. A suitcase with expandable features will allow you to keep it compact on the way there, and you can rest assured even if your luggage increases on the way back.

■ デザイン：ファッションに馴染む質感と上品なカラー

You don't want your suitcase to be broken into or stolen while traveling. By choosing a suitcase equipped with a reliable TSA lock, you can store your luggage with peace of mind. Ideally, it should be made of durable polycarbonate or ABS material to protect the contents from external impacts. A durable suitcase will last for a long time and prevent any trouble during your trip.
