Paul Stuart Men's 'Floatable Karami' Jacket
The "Paul Stuart" men's brand, operated by Sanyo Shokai, will begin selling the "Floatable Karami" setup (two styles: jacket and pants), which pursues lightness and coolness from both yarn and weave perspectives, starting April 1. It will be available at a total of 44 stores, including department stores and direct retail shops nationwide that carry "Paul Stuart" men's wear, as well as on the official Sanyo Shokai online store, "SANYO ONLINE STORE".
In response to the recent normalization of extreme heat, the "Floatable Karami" setup was developed to pursue even greater lightness and coolness, originating from the "Floatable Series" which strives for an overwhelming lightness that feels as if you are floating. While maintaining the thin and light wearing feel of the series' staple "hollow fiber", combining it with Karami weave has further improved its lightweight nature and breathability. By weaving the fabric in Hokuriku and finishing it in Bishu, and thereby cross-pollinating the techniques of domestic production areas, we propose this as special, high-quality cool-biz wear that possesses the elegance of natural materials despite being a highly functional fabric.
■ Background of Product Development
~ Expanding Cool Biz Demand Amidst Successive "Hottest Summers" ~
In recent years, due to the effects of climate change, the "hottest summer" has continued for three consecutive years up to 2025 (*1), making extreme heat the norm. With the average temperature for this summer (June-August) predicted to be higher than average (*2), our company anticipates a further expansion in the demand for cool-biz wear geared toward extreme heat. While attire is becoming more casual due to this background and the diversification of work styles, there is an increasing number of customers demanding not only "light and cool" business wear but also a "high-quality feel" and a "special feeling distinct from others."
~ Evolution of the Strong-Performing "Floatable Series" and a New Cool Biz Proposal ~
To meet these needs, "Paul Stuart", which provides high-quality business wear with outstanding techniques, has previously developed cool-biz wear that balances functionality and quality through its "Floatable Series". The jacket series utilizing hollow fiber, which has been on sale since 2023, has become a summer staple item. The "Floatable Hollow Fiber Seersucker Jacket" launched in 2025 recorded the top jacket sales within the brand in the spring/summer season of the same year. For 2026, we have further evolved the conventional "Floatable Series" setup and decided to develop the "Floatable Karami" setup as high-quality cool-biz wear that multiplies domestic technologies.
