航空会社や機材によって異なりますが、座席下に収納できる場合もございます。

ただし、本製品は縦50cm以上あるため、前方にはみ出したり、客室乗務員より頭上の収納棚へ移動するよう案内される場合があります。

基本的には頭上の収納棚をご利用いただき、座席下への収納可否は事前に各航空会社へご確認ください。

一般的な目安として、夏は2〜3泊、冬は1〜2泊程度になります。

※荷物量や衣類の厚み、持ち物、パッキング方法によって収納できる量は異なります。

耐荷重の目安は15kg程度です。ただし、荷物が重いほどキャスターやハンドルへの負担も大きくなるため、長く快適にお使いいただくには10kg前後を目安にすることをおすすめしております。

最大16インチ程度のノートPCを収納可能です。

PCスリーブはバッグ前面側にあるため、重量のあるPCを収納し、荷物が少ない場合は前方へ傾きやすくなります。

必要に応じて、PCや重い荷物を背面側に配置するなど、重心のバランスを調整してご使用ください。

Unfortunately, we do not currently have any physical stores and only sell our products online. We appreciate your understanding.

The wheeled board rotates around the connecting joint and retracts into the main body. Built-in magnets secure the board, preventing accidental opening or wobbling. The connecting joint is made of 1680D reinforced nylon and features reinforced stitching. The magnetic force is moderate and there is a frame, so the impact on electronic devices is extremely low.

Yes. The soiled casters and surrounding areas are covered by the wheeled board as soon as it's retracted. Since they don't directly touch your clothes, you can rest assured about hygiene.

Because of the built-in board, it's slightly less spacious than a typical backpack. However, the thick shoulder straps and back cushioning are designed to distribute the load and minimize strain. And when you get tired, you can roll it on its wheels, so there's no need to carry it on your back for extended periods.

The shoulder straps can be stowed in the back pocket, preventing them from touching the ground. To prevent damage to the shoulder straps from dragging, please be sure to store them in the pocket when rolling the bag.

By extending the casters, the bag can stand on its own. When you put down the backpack, the bottom of the bag does not directly touch the ground, so you can set it down without worrying about dirt. *Please note that the bag does not stand on its own when the casters are retracted.

Yes, it's possible. You can replace them yourself in about 15 minutes using the separately sold "Caster Replacement Kit."

鍵は付属しておりません。必要に応じて市販の南京錠や簡易ロックをご使用ください。ファスナーのロック穴は約5mmです。

バッグ内部の背面側にある持ち手のないファスナーは、製造・メンテナンス時に内部構造へアクセスするためのものです。通常の収納スペースではございませんので、お客様ご自身では開閉せず、そのままご使用ください。

撥水性のある素材を使用しておりますが、完全防水ではございません。激しい雨や長時間の雨では水が染み込む可能性があります。また、新品時の防水・汚れ防止スプレーの使用はおすすめしておりません。撥水加工との相性により白いシミが残る可能性があるため、撥水性が落ちてきた場合に、目立たない場所で試してからご使用ください。

Store in a well-ventilated place, away from direct sunlight and high temperatures and humidity. To clean the body, gently wipe with a damp, soft cloth. If the inside is heavily soiled, use a diluted neutral detergent.
