1. Three points to consider when choosing a waterproof suitcase

Title

The important thing to consider when choosing a waterproof suitcase is:
It's not about the appearance or the brand name, but the "functional content" such as the material, structure and details .
By understanding these points and choosing accordingly, you can not only use it safely on rainy days,

You'll find a suitcase that you can use for a long time.

1. Choose by material

2. Choose by structure

3. Choose based on details

① Choose by material: Check the balance between waterproofness and durability

Title

The most important factor that determines the waterproofness of a suitcase is the material.
Currently, there are three main types:

素材 特徴 防水性 耐久性
PC（ポリカーボネート） 軽量で衝撃に強く、傷もつきにくい。 ◎ ◎
ABS＋PCハイブリッド ABSの軽さ＋PCの強度を兼ね備えたバランス型。 ○ ○
アルミフレーム 高級感と防水性を両立。ファスナー部分からの水の侵入も防ぐ。 ◎◎ ◎◎

💡Points:
For those who live in areas with a lot of rain or snow, or who frequently use the device on overseas business trips, we recommend PC material or aluminum frame types .
On the other hand, for those who prioritize light weight, the ABS + PC hybrid type is ideal.

Title

② Choose by structure: zipper type or frame type

Title

When considering waterproofness, the opening and closing structure is just as important as the material.

構造タイプ 特徴 防水性 メリット
ファスナー型 軽量・柔軟で開けやすい。止水ファスナー採用モデルなら防滴性UP。 ○〜◎ 軽くて持ち運びやすい
フレーム型 アルミ製フレームで隙間が少なく、水やほこりの侵入を防ぐ。 ◎◎ 高防水・高耐久・防犯性にも優れる

💡Points:
・If you travel a lot on business trips or rainy days → Frame type (e.g. New Trip 1101 )

・For everyday use and lightweight bags → Zipper type (e.g. New Trip 0501 / 0502 )

Title

3. Choose based on details: zippers, casters, and handles

Title

The waterproofness of a suitcase varies greatly depending not only on the body but also on the "detailed design."

  • Waterproof zipper : Specially coated zipper prevents rain from entering.
  • Caster structure : The shaft is waterproof and quiet, making it comfortable even on wet ground.
  • Handle design : It is important to choose a shape and material that will prevent water from collecting.

💡One thing that we would like to draw your attention to in particular is the "one-piece molding" .
The "1302" in the New Trip series uses this design, making it difficult for water to get inside even in rainy weather.

Title

2. Differences in waterproofing and durability depending on the material

Title

When discussing the waterproofness and durability of suitcases, differences in materials are essential.
Depending on the material, there are big differences in lightness, waterproofness, strength, price, etc.
Here we will take a closer look at the three most common materials (PC/ABS+PC/aluminum), their characteristics, and how to choose them.

table of contents

1. PC (Polycarbonate)

2. ABS + PC hybrid

3. Aluminum frame structure

PC (Polycarbonate): Lightweight and highly impact resistant

Title

Polycarbonate (PC) is the most common material used in suitcases today.
It is so impact resistant that it is also used in aircraft windows and helmets, and it is also heat-resistant and waterproof.

💧Waterproof: ◎ → Resin material that is virtually impermeable to water. Surface coating for even greater water resistance.

Durability: ◎ → Resistant to cracking and deformation even when subjected to impact.

🧳Representative model:

💡 Recommended usage:
Ideal for those who prioritize lightness and portability, such as for trips or business trips of 1 to 3 nights.
This is a balanced material that is waterproof, lightweight, and quiet , so you can use it with confidence even in sudden rain.

Title

ABS + PC hybrid: a versatile material that is both light and strong

Title

A hybrid structure that combines the lightness of ABS resin with the strength of polycarbonate .
It is used in many New Trip models as an ideal material that is both light and strong.

💧Waterproof : ○ to ◎ →The PC layer repels rainwater and prevents water from seeping inside.

🧱Durability: ○ to ◎ →Lightweight yet resistant to cracking and deformation.

🧳Representative model:

💡 Recommended usage:
For those who prioritize lightness but also want peace of mind on rainy days and long-distance travel.
Models with waterproof zippers and expansion functions can flexibly respond to sudden changes in weather.

Title

Aluminum frame construction: The pinnacle of waterproofing and luxury

Title

The aluminum frame structure combines luxury with waterproof performance.
Because it opens and closes with a frame rather than a zipper, there are fewer gaps, which almost completely prevents rain and dust from entering.

💧Waterproof: ◎◎ →There is no zipper, so there are very few ways for water to enter.

Durability: ◎◎ → Resistant to deformation and can withstand long-term use.

🧳Representative model:

💡 Recommended usage:
Perfect for those who absolutely do not want the contents to get wet, such as during long-distance travel, overseas business trips, or during seasons with heavy snow or rain.
Another attractive feature is its solid and stable driving performance.

Title

"Comfort on rainy days" determined by the choice of materials

素材タイプ 防水性 耐久性 軽量性 特徴
PC（ポリカーボネート） ◎ ◎ ◎ 軽くて丈夫。雨の日にも安心。
ABS＋PCハイブリッド ○〜◎ ○〜◎ ◎◎ 軽量性と強度のバランスが優秀。
アルミフレーム ◎◎ ◎◎ △ 高防水・高級感・防犯性に優れる。

4. How to maintain your waterproof suitcase for a long time

Title

No matter how waterproof and durable a suitcase is,

Without proper care , the performance of the product cannot be maintained for a long time.

In particular, if you leave moisture, dirt, and humidity after moving in the rain or snow, it can lead to deterioration of the material and rust on the metal parts.
Here we will explain how to care for your waterproof suitcase to make it last longer .

3. How to use a waterproof suitcase cover

1. The key is to dry and store after use

Title

If you use your suitcase on a rainy day, dry it as soon as possible after returning home.

1. Wipe off any water droplets with a soft cloth . Thoroughly wipe off any moisture from the body surface, handles, and around the casters.
We recommend using a highly absorbent cloth such as a microfiber cloth.

2. Don't forget the zipper. Even if the zipper is waterproof, moisture remaining in the details can cause deterioration.
It's a good idea to wipe away any moisture from the grooves with tissue or a dry cotton swab.

3. Dry in the shade in a well-ventilated place. Avoid direct sunlight as this may cause the resin to deform.
Let it dry in the shade for about half a day before storing it.

💡 POINT:
When storing, do not seal in a plastic bag or case.
It is best to store it in a well-ventilated environment to avoid moisture buildup.

Title

2. Moisture protection for casters and handles

Title

Casters and handles are the areas most likely to collect moisture.
Leaving it for a long period of time can cause rust, creaking noises, and poor rotation .

1. To remove dirt from the casters, wipe them with a wet towel to remove mud and sand, then finish by wiping them with a dry cloth.
*Avoid using alcohol or strong detergents.

2. Apply a thin layer of lubricant to the metal shaft . Spray a light spray of lubricant (silicone type) on the shaft about once a month.
Maintains smooth running.

3. After extending or retracting the handle, wipe off any moisture. If water gets inside, it can cause rust or malfunction.
After use, dry thoroughly before storing.
