HEALTHKNIT / RAG Collaboration Long Sleeve Crewneck Open-End Dry Jersey Sweatshirt
From the collaboration between Healthknit and RAG comes a long-sleeve crew neck with the look of a sweatshirt. Made from the brand’s signature “Open-End Dry Jersey,” it is a highly functional piece.
It looks like a sweatshirt, yet wears like a long-sleeve tee—light, comfortable, and ideal for transitional seasons. Finished with antibacterial and deodorizing treatment, it works across everything from daily wear to active use. Easy to wear, yet still composed in appearance, it is an exclusive model made with the modern adult wardrobe in mind.

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.
RAG
A new line from ROCOCO, committed to transparent production backgrounds and reliable quality. Built around the concept of “urban outdoor active gear,” it delivers pieces that balance functionality with thoughtful design.



Comfort driven by functional fabric
The fabric has a balanced weight, blending American cotton with polyester for enhanced quick-drying performance and durability.
By using open-end yarn that traps more air than conventional yarn, it achieves a dry touch along with excellent moisture absorption and quick-drying properties. In addition, a silver-ion (AG+) treatment provides antibacterial and deodorizing performance, keeping it fresh even in warmer seasons.
A sweatshirt look, reimagined for lightness
The neckline features a classic crew design. Raglan sleeves enhance mobility around the shoulders, ensuring a comfortable, stress-free fit.
Ribbed cuffs and hem add a sweatshirt-like character, creating a clean silhouette with subtle structure despite the lightweight fabric.
Additionally, the hem is finished with RAG’s signature reflective logo, adding a discreet accent that highlights the exclusivity of this special collaboration.

Light, relaxed fit like a long-sleeve tee
The silhouette offers a relaxed fit with just the right amount of room. While it carries the visual presence of a sweatshirt, it feels as light and easy as a long-sleeve T-shirt.
Perfect as a standalone piece or layered under jackets and shirts, it works across seasons as a versatile, easy-to-style essential.
