Understanding Winter Comfort: The Shift Towards Merino Wool Innerwear

As winter approaches, women often face the discomfort of sweating under layers of clothing. A recent survey shows that nearly 80% of women experience sweat-induced discomfort during this chilly season. The survey, conducted by Tex-Knit Japan Inc., highlights the evolving preferences for winter innerwear, particularly the increasing interest in Merino wool for its unique blend of warmth, comfort, and moisture management.

The Survey Insights

Conducted between November 19-20, 2025, the survey gathered insights from over 1,000 female respondents aged 30 to 60, alongside dermatologists. It underscores a critical aspect of winter wear: functionality combined with comfort.

When asked about their experiences, 78.7% admitted to feeling uncomfortable due to sweating in winter. The primary qualities sought in winter innerwear revealed a compelling narrative; while warmth was crucial for 70.1% of respondents, there was a significant demand for lightness and moisture-wicking capabilities (33.8%).

The Material Debate: Cotton vs. Chemical Fibers

Cotton emerged as the most favored fabric (61.7%), closely followed by chemical fibers known for their moisture-absorbing properties. Although cotton is renowned for being skin-friendly, wearers noted its drawbacks: 36.8% reported issues with drying time, and 35.1% experienced discomfort from residual sweat leading to chilly sensations. Additionally, bacterial growth and odor (19.0%) were cited as significant concerns.

This raises questions about optimal fabric choices. With so many options available, where does one find a balance between the comfort of natural fibers and the efficiency of advanced textiles?

Merino Wool: The Versatile Solution

Amidst other materials, Merino wool stands out for its sought-after properties. Approximately 37.6% of participants recognized Merino wool and affirmed they had worn items made from it. This fiber not only ticks the box for warmth but also impresses with its soft feel, lightness, and excellent moisture-wicking capabilities.

Adopters of Merino wool highlighted several advantages:

• - It's known for being warm (42.3%).
• - It remains comfortable against the skin, devoid of irritating textures (40.2%).
• - Its lightweight nature allows for easier layering (26.3%).

This blend of characteristics shows a growing synergy with consumer needs for comfort and adaptability in winter wear.

Dermatologists' Concerns with Synthetic Fabrics

When dermatologists weighed in, they flagged several issues associated with chemical fibers: they can cause friction (37.3%), trigger itchiness (36.8%), and worsen skin dryness (32.1%). These insights amplify the growing conversation around how innerwear choices can significantly affect skin health, especially in winter when dryness is prevalent.

In fact, more than 90% of dermatologists surveyed expressed that they would recommend Merino wool innerwear, reinforcing its status as a reliable choice for winter wardrobes.

Conclusion: Beyond Warmth - The Importance of Comfort and Skin Health

The consensus from the survey reveals that women are evolving in their approach to winter innerwear. It's not merely about staying warm anymore; the complexities of maintaining comfort while managing sweat and skin health are now paramount.

Merino wool shows promise as a fabric that meets these needs, standing out for its luxurious softness, environmental benefits, and moisture-managing properties.
