The Best Foldable Rain-or-Shine Umbrella for Business Trips During the Rainy Season | How to Choose and Practical Test

Title

Have you ever felt like you "chose the wrong umbrella" for a business trip during the rainy season?

If you brought a rain-specific folding umbrella, you might have ended up drenched in sweat under the strong sun during a break in the rain.

If you brought a long umbrella, it wouldn't fit in your suitcase, increasing your hand luggage and making travel difficult. Many of you have likely had such experiences.

Conclusion: 3 Reasons why a folding sun/rain umbrella is ideal for business trips during the rainy season

  1. Portability that doesn't add to your luggage: Can be stored in a suitcase or business bag
  2. Adaptable to unpredictable rainy season weather: One umbrella covers both rain and sun
  3. Functionality for business settings: Combines quick-drying and durability

In this article, we will share the results of practical tests comparing folding sun/rain umbrellas, actually used on business trips during the rainy season, with other types of umbrellas.

What you will learn in this article

  • Specific requirements for umbrellas on business trips during the rainy season

一、実際に梅雨時期の出張で検証しました

Verification Period: June 15-19, 2025 (4 nights, 5 days)

Business Trip Destination: Tokyo → Osaka → Nagoya (travel by Shinkansen)

Weather Conditions

  • Rainy days: 3 days (1 of which was all-day rain)
  • Cloudy, then clear: 2 days
  • High temperature: 27-29℃
  • Humidity: 70-85%

Umbrella Used: New Trip Folding Umbrella for Sunny and Rainy Weather 7101

During this business trip, I visited 3-4 clients per day and walked a lot from the stations, taking out and putting away my umbrella an average of 6 times a day. The typical rainy season pattern of "sudden rain → clear spell → rain again" continued, making for ideal conditions to verify the practicality of the umbrella.

二、梅雨の出張で傘に求められる5つの条件

Based on my business trip experiences and this verification, I have summarized the necessary conditions for an umbrella for business trips during the rainy season.

1. 携帯性:荷物を増やさない

For business trips, it is essential that items can be stored in a suitcase or business bag.

Increased carry-on luggage adds to travel stress.

This particularly affects placing luggage on and taking it off the overhead racks of Shinkansen trains, and getting in and out of taxis.

2. 晴雨両対応:予測不能な天気への対応力

During the rainy season, weather forecasts are often inaccurate,

and situations such as "it was forecast to rain but it cleared up" or "it was forecast to be sunny but it suddenly rained" occur frequently.

A rain-specific umbrella cannot cope with strong sunshine during clear spells, and a parasol is inconvenient for sudden rain.

3. 耐久性:頻繁な開閉に耐える強度

When on a business trip, I open and close my umbrella many times a day.

From the station to the client, from one client to the next, going out for lunch, and so on—the number of times I open and close it is much higher than you might expect.

Cheap umbrellas can bend their ribs or break their opening/closing mechanism within just a few days.

4. 速乾性:ホテルや訪問先での扱いやすさ

How you handle a wet umbrella is important in business settings.

If water keeps dripping when you put it in the umbrella stand at your destination, it creates a poor impression.

Even in a hotel room, it's inconvenient if it doesn't dry by the next morning.

5. ビジネスシーンに適したデザイン

It is also important that the design is not too flashy and does not look cheap.

When folding an umbrella before meeting a business partner, the manner in which you do so can influence their impression of you as a businessperson.

三、一般的な傘タイプとの実用比較

We compared the New Trip foldable sun/rain umbrella with a typical umbrella in an actual business trip scenario.

長傘(雨専用)との比較

Portability and Storability

  • Full-sized umbrella: Doesn't fit in a suitcase, always needs to be carried by hand
  • New Trip: Fits in a suitcase's inner pocket, leaves hands free
  • Evaluation: For business trips with frequent travel, New Trip's portability is overwhelmingly advantageous.

Stability During Use

  • Full-sized umbrella: Strong against wind, large canopy provides good rain protection
  • New Trip: 98cm canopy diameter is perfectly adequate for practical use, automatic open/close allows for easy one-handed operation.
  • Evaluation: With powerful C6 water-repellent coating, it delivers overwhelming performance even on rainy days.

Practicality Evaluation for Business Trips

  • Full-sized umbrella: Cannot protect against sun on clear days, cumbersome as luggage
  • New Trip: Can be used for both rain and shine, doesn't add to luggage burden
  • Evaluation: New Trip is practical for business trips during the rainy season.

コンパクト折りたたみ傘(雨専用)との比較

Size and Weight

  • Rain-only folding umbrella: Approx. 20cm when stored, weighs 150-200g
  • New Trip: 31cm when stored, weighs 330g
  • Verdict: The New Trip is slightly heavier and longer.

Adaptability for Sunny Weather

  • Rain-only: No parasol function, useless when it's sunny
  • New Trip: UV cut rate over 99%, shading rate 100%, excellent as a parasol
  • Verdict: On days with frequent sunny spells during the rainy season, the New Trip's advantages are clear.

Difference in Durability

  • Rain-only: Cheap ones have weak ribs and can deform after a few uses.
  • New Trip: The automatic opening/closing mechanism is solid, no issues even after 20+ operations over a 5-day trip.
  • Verdict: For frequent business trips, the New Trip's durability provides peace of mind.

長傘タイプの晴雨兼用傘との比較

Ease of Handling (as luggage)

  • Long umbrella type: Always needs to be carried by hand, risk of forgetting on trains or in taxis
  • New Trip: Can be put in a bag, low risk of forgetting
  • Assessment: The more frequently you travel on business trips, the more advantageous the New Trip is.

Differences in Functionality

  • Long umbrella type: Large canopy, high sunshade performance as a parasol
  • New Trip: Fully opaque and perfectly practical, easy to use with automatic opening and closing
  • Assessment: No significant difference in functionality, New Trip wins in portability.

Usability in Different Business Trip Scenarios

  • Long umbrella type: No problem for business trips primarily involving car travel
  • New Trip: Ideal for business trips involving public transport and extensive walking
  • Assessment: Since most business trips fall into the latter category, New Trip is more practical.

実際の出張での使用記録

Storage in a Suitcase

When stored, the umbrella (31cm long x 6cm wide) fit into the inner pocket of a carry-on size suitcase (40L). While slightly larger than a typical folding umbrella, its 98cm canopy provides a wide, highly practical coverage.

At 330g, it is slightly heavier than ultra-lightweight models, but this is due to its sturdy frame, which provides stability. I didn't notice the weight when carrying it in my business bag.

User Experience in Rain (3-Day Record)

  • Day 1 (Light Rain): Walking 10 minutes from the station to the client's office, it provided ample coverage for both myself and my belongings. My shoulders didn't get wet even while carrying a business bag. The automatic open/close feature was convenient, allowing operation with one hand while holding my business bag.
  • Day 2 (All-day Rain with Wind): Opened and closed 8 times in one day. The wind picked up in the afternoon, with strong gusts, but thanks to the 8-rib hybrid structure, the umbrella remained stable and did not invert. While other people's umbrellas broke, the New Trip had no issues at all.
  • Day 3 (Rain then Cloudy): Thanks to the C6 water-repellent coating, few water droplets remained after folding the umbrella. When placing it in umbrella stands at client locations, it didn't drip water, which made a good impression. After drying it overnight at the hotel, it was completely dry and comfortable to use again the next day.

Effectiveness as a Parasol in Sunny Weather

  • Day 4 (Cloudy then Sunny): The afternoon was humid with temperatures at 29℃ and 80% humidity. Used as a parasol while walking 15 minutes from the station to the client's office.
  • Perceived Temperature Difference: Compared to a colleague who walked without a parasol, I felt noticeably cooler. Due to its complete light-blocking properties, direct sunlight from above was completely blocked. The large canopy provided a wide shadow, extending to my shoulders and arms.
  • UV Cut Effect: I had forgotten to apply sunscreen to some parts of my arms, but the areas under the umbrella did not get sunburned, confirming the UV cut rate of over 99%.
  • Effect of 9cm Extended Handle: My hand didn't get tired even after holding it for a long time, demonstrating the benefits of its ergonomic design.

Drying Speed After Getting Wet

  • Water Repellency Test: After rain, just two to three shakes of the umbrella removed most of the water droplets from the surface. Thanks to the C6 water-repellent coating, water beaded up and rolled off, not soaking into the fabric.
  • Indoor Drying: When opened and air-dried in a hotel room, it was completely dry in about 2 hours. It was ready for storage by the next morning.
  • Comparison: A typical rain-only folding umbrella took 5 to 6 hours under the same conditions. The difference in water-repellent coating quality significantly impacts drying speed.

Durability Test

  • Number of Openings/Closings: Over 25 times during a 5-day business trip, and the automatic open/close mechanism had no issues at all. Smooth operation was maintained.
  • Frame Strength: Used many times on windy days, but the ribs did not bend or deform. I truly felt the effectiveness of the high-strength aluminum alloy x fiberglass hybrid structure.
  • Fabric Condition: The 310T pongee fabric showed no fraying or tearing whatsoever, despite frequent opening and closing. The PU coating on the back enhances the fabric's durability.
