Experience Ultimate Comfort with SCiENSLEEP×UCHINO Marshmallow Gauze Pajamas

The Launch of SCiENSLEEP×UCHINO Marshmallow Gauze Pajamas

Starting November 16, 2025, the innovative SCiENSLEEP×UCHINO Marshmallow Gauze pajamas will be available for early purchase on Makuake, the popular crowdfunding platform. This exciting collaboration between the well-established brands SEESAY and UCHINO combines cutting-edge technology and luxurious comfort to redefine the pajama experience as we know it.

SEESAY, a 100% subsidiary of Gunze Corporation based in Osaka, focuses on developing sleep solutions through scientific analysis of body movements. It has partnered with UCHINO, a specialized towel manufacturer renowned for their exceptional fabric technology, to create pajamas designed to enhance sleep quality. The Marshmallow Gauze fabric is engineered with the user in mind, offering qualities that promote comfort and support during rest.

Innovative Materials and Design

The key to the Marshmallow Gauze pajamas lies in its proprietary fabric technology that features a unique three-layer structure. This setup incorporates soft threads on the surface and back, with a durable core layer sandwiched in between. This not only ensures a plush touch but also enhances durability, which is a hallmark of UCHINO's legacy in towel manufacturing over the past 40 years.

Moreover, the pajamas come with a GUNZE-exclusive drop shoulder design that minimizes strain on the arms and shoulders. Grounded in rigorous scientific research, this design significantly reduces muscle engagement during nighttime movements, verified through electromyography and motion capture analyses. This means wearers can roll over easily during sleep without strenuous muscle work, facilitating a deeper, more restful slumber.

Comfort Features

The Marshmallow Gauze pajamas have been crafted to deliver multiple comfort features:
1. Gentle on the Skin: The thoughtful yarn weaving and unique structure of the Marshmallow Gauze ensure that the fabric is soft against the skin while also minimizing friction that could lead to irritation.
2. Optimal Thermal Regulation: The innovative fabric strikes a perfect balance between warmth, breathability, and moisture absorption. This makes the pajamas an ideal choice for year-round wear, keeping sleep conditions comfortable irrespective of the season.
3. Stylish One-Mile Wear Design: Not only dedicated to function, but these pajamas also feature a contemporary, stylish aesthetic that reimagines traditional nightwear. With an oversized shirt fit, they offer both a relaxed feel and a fashionable silhouette, suitable for lounging at home or running short errands.
