"I want to wear it all day, from summer nights to mornings." Introducing the long-awaited short-sleeve version of the stretchy cotton gauze pajamas and loungewear.

Enfactory Inc. (Head Office: Chiyoda-ku, Tokyo; Representative Director: Kenta Kato), which operates the online select shop "Style Store," has launched a new short-sleeve version with a cool-touch feel (https://stylestore.jp/products/detail/166840) of its popular "Stretchy Cotton Gauze Pajamas and Loungewear." This allows customers to enjoy their original wear, developed from the fabric to balance good sleep and design, even more comfortably during the summer months.

The Style Store (https://stylestore.jp/) is a select shop that opened in 2005. It gathers items for living, food, and clothing from across the country, showcasing the faces of the creators and sharing their stories and backgrounds. We aim to be a place where we can co-create a "healthy lifestyle" with our users.

A new summer staple is added to the popular cotton gauze loungewear.

The "Stretchy Cotton Gauze Pajamas and Loungewear," released in Spring 2025, has been highly praised by many customers, with feedback such as "my sleep quality has improved" and "it's comfortable yet looks stylish enough to wear as loungewear." Since its release, it has steadily gained fans, attracting numerous media inquiries.

Many of the voices we received from our loyal customers were requests for a summer version: "It would be great if we could wear it in the summer too."

In response, we developed a new original gauze fabric from scratch, made of 100% cotton with a slight cool-touch sensation, and created summer-appropriate 5-sleeve pullovers and pants. They are available for both women and men.

Size S, Men's, New Colors – A Year of Expanding the Lineup Based on Customer Feedback

Initially, this series started with women's sizes M, L, and XL, in two colors: navy and dark gray. Since then, we have steadily expanded the lineup based on customer feedback.

The S size was created in response to requests from petite individuals who said, "The design is a bit loose, so I'd like an S size." The men's line was launched due to comments like, "I liked it so much myself, I'd like a men's size for my husband." Furthermore, a soft light green was added after a suggestion that "a slightly brighter color would be nice."

This new summer item was also born from customer requests to "wear it in the summer."

Why is it so comfortable? 100% Cotton W Gauze, the Reason for Developing the Fabric from Scratch

This W gauze fabric is made by loosely knitting thin 100% cotton threads into a double-layered fabric. The inner layer uses 100% cotton cool-touch yarn. While gauze material generally lacks elasticity, the fabric we developed stretches well and is lightweight.

To support sound sleep, three factors are considered important: 1 breathability, 2 ease of movement during sleep, and 3 a pleasant feel against the skin. We continuously searched for fabrics that met these three conditions but struggled to find ideal options on the market. While 100% cotton gauze, a natural material, excels in breathability and moisture absorption, it typically lacks elasticity, which can cause a feeling of tightness when turning over.

Therefore, we developed an original W gauze fabric by loosely knitting thin 100% cotton threads into a double-layered structure. It is lighter than it looks, stretches flexibly with body movements, and doesn't get stuffy even when you sweat. Additionally, by using 100% cotton cool-touch yarn on the inside, it provides a slightly cool feel against the skin.

"Not like pajamas," so you can go out in them.

While pursuing comfortable wear, the "appearance" has been a consistent focus for these loungewear items.

The pullover has a relaxed fit in the body, shoulders, and upper arms, but is designed with a silhouette that falls straight down to flatter the female form. The pants are tapered and feature pleats that create a vertical drape, giving them a neat appearance.

Combined with the subtle sheen from the mercerization process, some users have reported wearing them out for short errands, such as picking up packages or dropping off children at school, by simply layering a cardigan over them, functioning as "one-mile wear."

Choose your material for summer nights. The long-awaited short-sleeve version is here.

In recent years, with heatwaves lasting longer, sometimes feeling like half the year, summer night sleep environments have become an increasingly pressing issue. In this new product, by using 100% cotton cool-touch yarn on the inside of our original W gauze fabric, we have achieved a cool sensation the moment it touches the skin. It retains the inherent breathability and moisture absorption of gauze while reducing the "stuffiness" and "stickiness" unique to summer nights.

With no sleeves, it's even cooler, yet it can be worn as loungewear throughout the day, making it an item to enhance your summer sleep comfort.
