【Survey】Rainy Season Stressors: “Going Out” and “Damp Clothes Odor.” Stay Comfortable with Quick-Dry, Cooling Apparel

tu-hacci (pronounced "Tu-Hatchi"), an inner fashion brand operated by WaterAir Co., Ltd. (Headquarters: Hiroshima City, Hiroshima Prefecture; CEO: Shunosuke Kuniyasu), conducted an awareness survey titled "Survey on Rainy Season Stress" among 492 of its social media followers. The results revealed that approximately 70% feel stressed about going out on rainy days, with many struggling with damp clothes odor and discomfort from clothing sticking to their skin. In response, tu-hacci is introducing its latest apparel and innerwear featuring high-performance quick-dry, odor-control, and contact-cooling functions, enabling people to stay comfortable and stylish from rainy to sunny days.

The Increasing Discomfort of the Rainy Season: Consumers’ Dilemma Over Going Out and Clothing Choices

With climate change causing higher humidity, increasing emphasis on efficient daily mobility, and rising self-care trends prioritizing personal comfort, modern consumers’ standards for comfort are evolving every year. The rainy season, in particular, is a time when prolonged humidity prevents clothes from drying properly, leading to accumulated minor stress in everyday life.

During this season, issues such as getting wet during commutes or grocery shopping—"wetness when going out"—along with resulting "damp clothes odor" and the discomfort of "clothing or underwear clinging to the skin" have become serious concerns for many women. While there is growing market interest in quick-dry and anti-odor products, consumers often struggle with items that are "too sporty in design to wear casually" or want to "stay comfortable without sacrificing a flattering silhouette." Many people feel torn between functionality and fashion, finding it difficult to have both.

Visualizing Women’s True Feelings About Rainy Season Stress and Clothing

To uncover real consumer insights and propose clothing-based solutions, tu-hacci conducted a survey titled "Rainy Season Stress Survey" among followers of its official Instagram account.

The survey was conducted in May 2026 using Instagram Stories, collecting valid responses from 492 women.

Hidden in everyday life are honest desires such as "I wish I could live more comfortably according to the season" or "I wish there was clothing like this." This time, these season-specific concerns and needs, felt by many but rarely voiced, have become clearly visible.

Three Key Discoveries About Rainy Season Micro-Stress and Clothing

【Discovery 1】The top life stress during the rainy season is "going out in rain or humidity."

When asked about the most stressful aspect of life during the rainy season, a clear majority—72%, or roughly seven in ten—responded with "going out in rain or humidity."

This far exceeds concerns such as "laundry not drying (24%)" or "utility costs for air conditioning and dryers (4%)," indicating that the burden of stepping outside—whether for commuting or shopping in the rain—is the most significant stressor.

【Discovery 2】Top clothing and innerwear discomfort: "damp clothes odor," followed by "clinginess to skin."

Next, when asked about the most stressful aspect of clothing and innerwear during the rainy season, "damp clothes odor" ranked highest at 41%, followed by "clothing or underwear sticking to the skin" at 35%, and "worry about sweat stains" at 24%.

The survey revealed that odors from clothes dampened by rain and humidity, along with stickiness caused by high moisture levels, significantly impair women’s comfort when going out.

【Discovery 3】Differentiated use of "quick-dry outerwear" and "anti-odor, anti-cling innerwear" is essential.

Analyzing the results, it became clear that consumers have dual needs: an external need for quick-drying outerwear to prevent the discomfort of wet clothes lingering after rain, and an internal need for protective innerwear to prevent moisture, odor, and sweat stains inside clothing. To comfortably endure the rainy season, it is crucial to adopt independent strategies—outerwear that dries instantly when wet, and high-performance innerwear that resets internal discomfort.

Functionality is essential—but appearance matters too: The modern demand for “urban-comfortable” style

The survey results clearly show that many women are deeply dissatisfied with rainy season issues such as "getting wet when going out," "damp clothes odor," and "clothing clinginess," highlighting a growing market expectation for "quick-dry, anti-odor, and contact-cooling items."

Consumers’ true feelings reveal a modern desire to not compromise on either practicality or fashion: "rainwear is too sweaty and too casual in design," or "I want to wear sweat-control innerwear but still want a beautiful bust silhouette." More than just protecting against rain and sweat, today’s clothing must enhance one’s style and boost confidence. Refined designs that achieve both are becoming the new standard for seasonal wardrobe choices.
