HEALTHKNIT / RAG Collaboration Freedom Long Sleeve T-Shirt Open-End Dry Jersey
This long-sleeve T-shirt may look cotton-like, but it offers unexpected technical performance. The combination of fabric and silhouette is an exclusive model created only for ROCOCO’s original label, “RAG.”
The fabric has a substantial feel with a dry touch and comfortable texture, using an open-end yarn blended from cotton and polyester. Because the yarn contains plenty of air, it provides excellent moisture absorption and quick-drying functionality.
Finished with antibacterial and deodorizing treatment, it is a dependable long-sleeve T-shirt for everyday wear, even in 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 also 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.
While maintaining a classic, cotton-like appearance, it offers a high level of practical functionality.
Relaxed, considered detailing
The neckline features a crew neck with a balanced opening. Around the shoulders, the front sleeves use a raglan construction, while the back transitions into a yoke sleeve, creating a subtle visual accent while ensuring a stress-free fit.

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.
Well-balanced sizing
A relaxed silhouette with added room through the body and shoulders. The carefully adjusted length avoids any bulky impression, resulting in a clean, refined look.
Designed to suit a wide range of body types, it offers versatility that adapts easily to various styling approaches.
