A Refined Essential for Everyday Life.
This long sleeve wool T-shirt features a refined mock neck design. Made from high-quality Japanese fine merino wool, Super100’s, it combines a cashmere-like softness with an elegant and calm appearance. From business layering to casual outings, this ultimate basic piece elevates your everyday style with effortless sophistication.
Designer’s Commitment
C-one’s T-shirt is more than just a piece of clothing. To bring comfort and refinement to everyday life, the designer’s passion and philosophy are woven into the details that are not immediately visible.
The mock neck is designed with a carefully balanced fit that does not feel tight around the neck. Because the collar is set slightly higher, it helps prevent rubbing and stains around the neckline when worn under a jacket, reducing the need for frequent jacket cleaning. With no itchy feel, it keeps you comfortable while maintaining an elegant impression.
The cuffs and hem are finished with a switched design that creates a clean, well-balanced silhouette. When worn, it naturally follows the body, preventing bulk around the underarms even when layered under a jacket or outerwear. It maintains an elegant look and offers excellent durability against shape loss after washing.

Super100’s Merino Wool: Six Essential Functions
Super100’s merino wool is the premium material shared across all C-one items. This single piece can transform your everyday comfort.
Merino Wool Mock Neck Long Sleeve T-shirt: C-one’s Commitment in Every Detail
From material selection to sewing techniques, no compromises are made. We deliver a piece that brings satisfaction every time you wear it.
The natural drape of Super100’s merino wool is combined with C-one’s original pattern. It does not cling too closely to the body, creating a beautiful and natural drape. Casual yet refined, it brings a polished sense of maturity to your style. Easy to pair with a wide range of bottoms, it enhances the wearer’s everyday look.
To bring out the best qualities of delicate Super100’s merino wool, C-one is committed to knitting and sewing by skilled Japanese artisans. The craftsmanship hidden in the unseen details supports excellent durability, helping the garment maintain its shape even after repeated wear and washing. It is proof of true quality made to be loved for years.
By working directly with trusted domestic factories without going through trading companies, we are able to fine-tune specifications and thoroughly check quality. This allows us to create wool wear with uncompromising comfort and tailoring. By reducing unnecessary distribution costs, we deliver a level of quality that would normally be more expensive at a fair price. We want to offer true value that you can feel not only in appearance, but also when it touches your skin and when you continue wearing it. This is the foundation of C-one’s craftsmanship.
