1. What is a lightweight suitcase? Check the weight standards

Title

This model is designed to be approximately 1 kg lighter than a typical suitcase.
They are often called "lightweight suitcases," and types designed to weigh around 3kg are particularly popular.
The appeal of lightweight models is that they make all movements, such as lifting, pulling, and climbing stairs, smoother.
Recently, there has been an increase in "high-performance lightweight models" that are not only lightweight but also equipped with silent casters and expansion functions.

2. Factors that determine lightness: materials, structure, and parts

Title

The "lightness" of a suitcase is not simply a matter of weight, but is achieved through the balance of materials, structure, and part design .
This chapter explains three key points that support weight reduction.

Title

1. Material | Balance of lightness and durability

The material has the biggest impact on how lightweight a suitcase is.
Let's take a look at the four most common characteristics.

素材 軽さ（目安） 特徴
ABS樹脂 比較的軽い（目安：約2.6〜3.2kg） コスパ良・デザイン豊富。板厚による差が小さい。
ハイブリッド（PC＋ABS） 軽量〜中量（目安：約2.7〜3.1kg） 耐久性と軽さのバランス。New Tripの代表的素材。
ポリカーボネート（PC） やや重め（目安：約2.8〜3.4kg） 衝撃吸収性が高く、薄く仕上げやすいが密度は高め。
アルミ・マグネシウム合金 重め（目安：約3.5kg〜4.5kg以上） 高剛性・高級感。最も堅牢だが重量増になる。

※上記は一般的な目安です。実際の重量は板厚、内装、補強構造、フレーム方式など設計次第で変わります。
New Tripの 0201 （2.8kg）や 0701 Plus （2.9kg）は、設計で軽さと強度を両立させた好例です。

Title

2. Structure | Lightweight yet strong frame design

The internal structure of the suitcase is also key to reducing weight.
Recently, the mainstream design has been to use "rib structures" and "inner rib reinforcement" to reduce plate thickness while maintaining strength.

Also, zippered types tend to be lighter than framed types .
Many New Trip models also feature a zipper structure that prioritizes lightness and flexibility.

Title

3. Parts | Lightweight design even in invisible parts

It's not just the exterior that affects lightness.
The handles, casters, and interior materials have also been carefully designed.

  • Casters : Made of lightweight material that is quiet and reduces friction, allowing for easy rolling.
  • Handle : Made of aluminum, it is light and provides a stable grip.
  • Inner material : Water-repellent nylon and lightweight fabric are used to reduce overall weight.

💡 ポイント

  • 軽量スーツケースは、「1つひとつのパーツを見直す設計思想」から生まれます。
  • New Tripでは、耐久性を損なわずに重量を削減する“構造の工夫”にこだわっています。

3. How to choose a lightweight suitcase [4 points]

Title

"I chose a lightweight suitcase, but it was surprisingly difficult to use..."
To prevent such mistakes, it is important to have a total balance that includes not only lightness but also ease of use and durability .
Here are five points to consider when choosing a lightweight suitcase.

Title

1. Find the right balance between lightness and durability

Extremely light suitcases may be made of thin materials or have little reinforcement.
Lightness means ease of handling, but if the material is weak to impact, the risk of breakage increases .

💡We recommend " PC + ABS hybrid material " or " 100% polycarbonate ".
A structure that combines lightness and durability.


The New Trip 0201 (2.8kg) is a prime example of this balance.
Title

2. Silence and smooth running of casters

Even if it's light, if the casters don't move well it can be a source of stress.
Lightweight suitcases tend to have a high center of gravity due to their structure, so smooth and stable caster performance is essential.

- 360° swivel double casters make it easy to change direction.

- Models equipped with silent casters make moving around comfortable even at night or early in the morning.

The New Trip 0201 and0701 Plus models feature high-quality, silent casters.

It is both lightweight and quiet.

Title

3. Security Features: TSA Locks Are a Must

If you want to use it safely when traveling abroad, it is best to choose one with a TSA lock .
Some lightweight models have simple locking functions, so be sure to check before purchasing.

💡 All New Trip models (0201, 0701 Plus, Monomi 0802, etc.) come standard with TSA locks .
It also makes airport inspections smooth and is ideal for overseas business trips and long-term travel.
Title

4. Internal structure and storage function

The lighter the model, the simpler the internal design tends to be,
The placement of dividers and pockets can make a big difference in packing efficiency .

- Mesh pockets and dividers included : Keeps your belongings organized

- Comes with a cross belt to prevent the contents from falling when opening and closing.

・Model with expansion function : No need to worry about extra luggage

The New Trip 0201 's capacity increases by approximately 20% just by opening the zipper all the way around.
This is a popular multi-functional model that is both lightweight and compact.

🧳 まとめ

  • 軽量スーツケースを選ぶときは、
  • 「軽さ」だけでなく「静音性」「強度」「機能性」もトータルでチェック。
  • あなたの旅のスタイルに合う一台を見つけることが、長く使える秘訣です。

Q2：海外旅行でも問題ない？

A2：問題ありません。むしろ、石畳や階段の多い海外では、軽量スーツケースの機動力が大きなメリットになります。ただし、セキュリティ対策として「TSAロック」、そして空港での手荒な扱いに耐えるための**「耐久性の高いキャスターと本体素材」**を選ぶことが重要です。

Q3：軽量モデルでTSAロック付きはある？

A3：ほとんどの主要メーカーの軽量モデルには、標準でTSAロックが搭載されています。もちろん、New Tripの全モデルにも標準装備されていますので、安心して海外旅行にご利用いただけます。
