CAMP Co., Ltd. (Head office: Shibuya-ku, Tokyo / Representative Director: Miho Sakakibara) will launch new summer models of "braless wear," which can be worn as a single layer directly on the skin without a bra, on May 1, 2026, via the official online store of its specialized brand "no-bu." This new clothing reduces the discomfort of "stuffiness and tightness" during hot seasons, achieving both comfort and a presentable appearance. In hot weather, many people experience discomfort from bra tightness and stuffiness. The company will offer the "Soyokaze Series," made from lightweight, breathable materials, and the "Silket Suzu Series," made from 100% cotton natural material with mercerized processing.
An updated version of the braless wear, which achieved over 10 million yen in support purchases on Makuake last year, is scheduled to begin pre-sales on Makuake from May 3, 2026.
We conducted a comparative verification of skin surface temperature using thermography when wearing a bra versus when wearing braless wear. The thermography comparison showed that the "heat buildup around the chest" observed when wearing a sample inner garment was dispersed with braless wear. The skin surface temperature was less uneven, confirming a state where one can feel cooler.

The concept of no-bu is "clothing that wears comfort." It is a brand that proposes "braless wear," a new clothing option that allows people to go out without wearing underwear. By using unique special technology that prevents sheerness around the chest without using rubber or wires, it achieves both a relaxed feeling and a presentable appearance suitable for going out. By creating it as "clothing" rather than "underwear," the brand aims for a daily life where bralessness can be naturally chosen. Since its launch on Makuake in July 2024, the total support purchases across three campaigns have reached 25.96 million yen, recording a huge hit.
The problem of bras in hot summer.
During hot seasons, many people complain about the discomfort caused by bra tightness and stuffiness. Especially in summer, wearing a bra, innerwear, and a T-shirt in layers can easily lead to heat buildup around the chest.
Stuffiness and heat around the chest, and sweat accumulating under the elastic band of the bra. Furthermore, in air-conditioned rooms, the sweat-soaked elastic band can feel cold, leading to many unique summer discomforts.
Against this background, there has been increasing interest in innerwear with less tightness and light, comfortable clothing in recent years.
no-bu proposes "braless wear" as a new option to liberate people from the discomforts of heat, sweat, and stuffiness around the chest, allowing them to wear it as a single layer without a bra. It is a new standard for spending a more comfortable summer.

Temperature comparison by thermography.
no-bu conducted a comparative verification using thermography to confirm the difference in skin surface temperature when wearing a bra versus when wearing braless wear. We compared wearing our own sample innerwear with wearing no-bu's braless wear to confirm changes in chest temperature. Even under the same conditions, there was a difference in heat dispersion. When wearing our own sample innerwear, heat accumulated in some areas, and temperature unevenness was observed. In the case of braless wear, the non-tightening design prevents heat from accumulating easily, resulting in a less stuffy feel.
Cleared public laundry test 100 times.
Safe for daily washing.
The chest pad part is designed to maintain a stable state even after repeated washing. Public testing institutions have also confirmed that the fixing strength is maintained in laundry tests.
Braless wear for a comfortable summer.

"During summer, we have received many comments from people who feel particularly stressed by bra tightness and stuffiness. We thought about how to reduce that discomfort as much as possible while also achieving a presentable appearance for going out, and that's how this summer's braless wear was conceived. It's not just about 'comfort only inside the house,' but also about wanting to cherish a 'neat appearance when going out'."
