HEALTHKNIT / RAG Collaboration Raglan Short Sleeve Wide T-shirt Open-end Dry Jersey
Though casual in appearance, this wide T-shirt is in fact packed with technical performance. The combination of fabric and silhouette is an exclusive model made only for ROCOCO’s original label, “RAG.”
The fabric has a substantial feel with a dry touch and comfortable feel, using an open-end yarn blended from cotton and polyester. Because the yarn contains plenty of air, it offers excellent moisture absorption and quick-drying functionality.
Finished with antibacterial and deodorizing treatment, it is a T-shirt you can rely on day after day, even through the warmer months.

RAG
A new line from ROCOCO, defined by transparent production backgrounds and a commitment to dependable quality. Built around the concept of “urban outdoor active gear,” it proposes pieces that balance functionality with considered design.
HEALTHKNIT
Founded in 1900 in Knoxville, Tennessee, as a manufacturer of high-quality knit underwear. Known for its signature henley neck T-shirt, the brand continues to oversee an integrated production process—from spinning to sewing—using premium materials sourced from the American South.

Comfort from functional fabric
The fabric has a balanced weight, blending moisture-wicking American cotton with polyester for quick-drying performance and durability.
It uses open-end yarn, which contains more air than conventional yarn, enhancing both moisture-wicking and quick-drying properties. In addition, a silver-ion (AG+) treatment provides antibacterial and deodorizing functionality.


A wide T-shirt with a relaxed feel
The neckline features a simple crew neck. Around the shoulders, the front sleeves use a raglan construction, while the back transitions into a yoke sleeve, adding a subtle visual accent while ensuring a stress-free fit.
The sleeve length is set at a balanced proportion, avoiding a bulky impression.
At the hem, a signature reflective logo from RAG and a HEALTHKNIT brand tag are placed, adding a subtle accent to the otherwise minimal design.
A contemporary wide silhouette
A box silhouette with generous room in the shoulders and body. Designed to suit a wide range of body types, it offers versatile styling options.
