二、ファスナータイプの特徴｜軽さと使いやすさを重視する人向け

Zipper-type suitcases use fabric or resin zippers and are often found in soft and hard cases. They have the advantages of being lightweight, expandable, and have high storage capacity, but you need to be careful about security and waterproofing.

Zipper-type suitcases use a fabric or resin zipper and are commonly found in both soft and hard cases. While they offer advantages such as being lightweight, expandable, and having good storage capacity, caution is advised regarding their security and waterproofing.

・ファスナータイプが軽量になりやすい

·lightweight :
It is significantly lighter than the frame type. For example, for the same size S, the zipper type New Trip 0201 weighs 2.8 kg, while the frame type New Trip 1101 weighs 3.85 kg. This makes it easier to comply with airline weight restrictions and makes it very easy to carry.

Flexible opening and closing :
Zippered suitcases can be partially opened, making it easy to access your belongings even in tight spaces. Two-way zippers allow for greater freedom of opening and closing, making it easier to organize your belongings.

・Extensions :
Many models feature an expandable gusset, increasing capacity by approximately 20% ( New Trip 0201 ), allowing you to accommodate souvenirs or additional luggage.

・Shock absorption :
The zipper type uses a flexible material that absorbs external shocks and reduces vibrations during transport, reducing the risk of damage to your luggage.
Title

・荷物が増えても対応しやすい

Low security: Zippers pose a risk of being forcibly opened, making them particularly unsuitable for protecting valuables. For enhanced security, it is recommended to choose a model with a YKK zipper or a TSA lock.

Low waterproofing : Water can easily seep in through the zippers of suitcases, and your luggage may get wet during heavy rain. Even silicone-coated zippers are difficult to completely waterproof, so you need to be careful when traveling to rainy areas.

- Transmission of impacts to the interior <br>Zipper types have a flexible structure, so external impacts are easily transmitted to the interior, so care must be taken with fragile items.
Title

・ファスナータイプの注意点

一方で、以下の点には注意が必要です。

  • ファスナー部分に負担がかかる：荷物を詰めすぎると、ファスナーやロック部分に圧力がかかります
  • 詰め込みすぎに注意：内側から膨らむと、開閉しにくくなることがあります
  • 開閉時の扱い：ファスナーを無理に引っ張ると、破損の原因になります

荷物は7〜8割程度に抑え、ファスナーを丁寧に扱うことで、長く使えます。

三、フレームタイプの特徴｜剛性と安心感を重視する人向け

・ Related Article: "TSA Lock and Frame Type - Choosing the Best Suitcase!"

Frame-type carry-on cases are hard cases that primarily use an aluminum frame and are designed with durability and security in mind, providing strong protection especially for long trips or when carrying valuables.

・フレーム構造によるケースの剛性

High durability and security <br>The aluminum frame is resistant to deformation and impacts, making it ideal for protecting valuables and fragile items. Its airtight seal protects your luggage from external damage ( New Trip 1101 ). The robustness of the frame is particularly emphasized in terms of security, allowing you to enjoy your trip with peace of mind.

Excellent waterproofing <br>The frame case features a sealed design that protects your belongings from rain and dust. The interior remains resistant to moisture even in heavy rain, making it especially useful in rainy or humid areas. (Compared to zippered cases, the waterproofing is even more superior.)

- Internal protection and organization <br>The interior is protected from external pressure by a sturdy frame, making it ideal for storing particularly fragile items (such as glassware or precision instruments). In addition, some models feature shelf-style storage, allowing you to organize your belongings efficiently.

Title

・ファスナーがない開閉方式のメリット

Weight: Frame types tend to be heavier than zipper types because they use materials such as aluminum frames. This can be inconvenient on airplanes with strict weight restrictions.

・Need for space to open and close <br>Many luggage have double doors, so they require a large space to handle. It can be inconvenient to open and close in small spaces, so you need to be careful when opening and closing them in hotel rooms, airplanes, etc.

Low flexibility <br>Frame-type bags are difficult to open and close partially, which limits how much you can put in and take out your luggage. This can be inconvenient if you need to take out your luggage in a hurry.

Risks when opening and closing: Many frame-type models use a lift lever, so there is a risk that the contents may fly out if the bag is handled forcefully at an airport, etc. To mitigate this issue, it is recommended that you securely lock the bag with a combination lock or TSA lock.

Title

・フレームタイプの注意点

  • 本体重量が増えやすい：フレームパーツの分、重くなります
  • 価格が高めになりやすい：構造が複雑なため、価格帯が上がる傾向があります
  • 開閉時にスペースが必要：全体を開けるため、狭い場所では扱いにくいことがあります
Title

四、ファスナー型とフレーム型、どちらを選ぶ？4つの判断基準

It's important to choose the zipper type or frame type based on their respective features to determine which is best suited to your travel style. The key to choosing will depend on the purpose of your trip and the points you prioritize.

・Zipper type

Zippered bags are ideal for travelers who prioritize lightweight and easy portability . They're flexible and easy to use, making them ideal for short trips and business trips . Many models also come with expandable features , allowing you to adjust the capacity as your luggage grows.

However, you should be careful about security when it comes to valuables or fragile items . This service is not suitable for items that require strong protection, so valuables will require separate security measures.

Frame type

Frame-type luggage is ideal for travelers who prioritize security and water resistance . The metal frame provides extra strength and excellent protection for valuables and fragile items. It is especially suitable for long-term travel, business use, and transporting fragile items.

However, frame-type lockers are heavier than zipper-type lockers and require a larger space to open and close. They can be difficult to use in tight spaces, so care must be taken depending on the situation.

軽さを重視するならファスナー型

以下に当てはまる方は、軽量なファスナー型がおすすめです。

  • 電車・新幹線での移動が多い
  • 階段でスーツケースを持ち上げる機会が多い
  • 機内持ち込みで使いたい
  • 力に自信がない

ただし、同じタイプでもモデルによって重量は異なります。購入前に実際の本体重量を確認しましょう。

ケースの剛性を重視するならフレーム型

1. Business trip (3 days - 1 week)

  • Recommendation: Zipper type
  • Reason:
    　Frequent airport transfers, so lightness is important
    　Needs to be opened and closed frequently in hotel rooms
    　Laptop can be easily taken out from the front pocket
    　Provides more leeway for airline weight restrictions
  • Example: New Trip 0702plus (front-opening design) allows you to take out your laptop immediately after security checks.
  • Note: Keep valuables in the hotel safe and minimize what you keep in your suitcase.

2. Family trip (1-2 weeks)

  • Recommendation: Zipper type (with expansion feature)
  • Reason:
    　Luggage tends to increase with children's clothes and toys
    　Expansion feature allows for a 20% increase in capacity, eliminating the need for additional purchases
    　Lightweight is advantageous when carrying multiple suitcases
    　Easy for children to open and close
  • Example: New Trip 0502 (large capacity + expansion feature) can accommodate souvenirs even if you buy more.
  • Note: To compensate for waterproofing, double-bag items in plastic bags on rainy days.

3. Long-term overseas travel (3 weeks or more)

  • Recommendation: Frame type
  • Reason:
    　Durability is important for long-term use (reduces risk of zipper wear)
    　Protection of valuables (passport, credit cards, cash) is essential
    　Increased risk of theft when traveling through multiple countries
    　High water resistance, adaptable to different climates
  • Example: New Trip 1101 (aluminum frame) can withstand multiple airport inspections and impacts on the ground.
  • Note: As it is heavy, ingenuity is required, such as reducing clothes with compression bags.

4. Carrying expensive equipment/fragile items

  • Recommendation: Frame type
  • Reason:
    　Reliably absorbs external shocks
    　High airtightness protects against humidity changes
    　Security lock prevents theft
    　Minimal internal pressure changes
  • Example: New Trip 1302 (front opening + internal protection) allows you to safely carry cameras and lenses.
  • Note: Consider taking out insurance to prepare for accidental damage.

5. Travel to rainy regions

  • Recommendation: Frame type
  • Reason:
    　No risk of water ingress from zippers
    　Sealed design prevents internal wetting even in heavy rain
    　Less prone to mold in humid environments
  • Example: For travel to Southeast Asia (Thailand, Vietnam) or monsoon regions, a frame type offers peace of mind.
  • Note: If using a zipper type, reinforce it with waterproof spray or silicone coating.

荷物量が増えやすいならファスナー型＋拡張機能

お土産や買い物で帰りの荷物が増えやすい方には、拡張機能付きのファスナー型が便利です。

  • 旅行先で買い物を楽しみたい
  • 帰りにお土産が増える
  • 行きと帰りで荷物量が変わる

ファスナー型は拡張機能を搭載したモデルが多く、容量を柔軟に調整できます。

耐久性は「タイプ」だけでは決まらない

Common Dilemmas and Solutions

  • "Is it possible to have both lightness and durability?"
     → While a perfect balance is difficult, you can enhance durability in zipper-type luggage by choosing high-quality YKK zippers or silicone coating. However, for long-term use, frame-type luggage is a safer bet.  
  • "What if I'm concerned about security?"
     → Even with zipper-type luggage, you can significantly reduce risk by choosing a model with a TSA lock and managing valuables separately in a security pouch.
  • "What if I'm on a limited budget?"
     → Zipper-type luggage is generally more affordable. If you primarily take short trips, zipper-type is sufficient. For long-term use, it's worth considering investing in frame-type luggage.
