C HIGH END Merino Wool Long Sleeve T-Shirt
Designed with a higher back neckline for jacket wear.
The luxurious touch of Super100’s wool refines your winter business style.
Super100’s Merino Wool: Six Essential Functions
The finest material shared across all C-one T-shirts. One piece that transforms everyday comfort.
A Refined Essential for Everyday Wear
This Japanese-made long sleeve T-shirt features a higher neckline, carefully designed to prevent jackets from directly touching the skin. Compared to conventional T-shirts, it reduces friction and discomfort. Made from fine merino wool, it offers excellent breathability and comfort, even in warmer seasons. A versatile piece suitable for business and casual wear alike.
Designer’s Philosophy
C-one T-shirts are not just garments. They are crafted to bring comfort and refinement into daily life, with meticulous attention paid to every unseen detail.
01. Jacket-Friendly Pattern Design
The carefully shaped neckline slightly peeks out from under a jacket, preventing direct skin contact and protecting the jacket from wear.
02. Timeless Unisex Silhouette

Perfect for work, shopping, travel, or everyday activities.
C HIGH END Merino Wool Long Sleeve T-Shirt:
Crafted with C-one’s Attention to Detail
From material selection to sewing techniques, no compromises are made. This is a piece designed to impress every time you wear it.
01. Premium Materials
The natural drape of Super100’s merino wool combined with C-one’s original pattern creates a refined silhouette without clinging to the body. Casual yet elegant, it pairs effortlessly with any bottoms.
02. Japanese Craftsmanship
To fully bring out the delicate nature of Super100’s merino wool, C-one relies on skilled Japanese artisans for knitting and sewing. The craftsmanship hidden beneath the surface ensures durability, shape retention, and long-lasting beauty.
03. Honest Pricing
By working directly with trusted domestic factories and eliminating intermediaries, we achieve uncompromising quality at a fair price. What you feel on your skin—and over time—is genuine value.

ウール素材は手触りがなめらかで、着心地は体にフィットします。
最近気温がちょっと下がっても暖かく対応できて、動いても締め付け感がなく快適そのもの。

洗濯をしたら襟ぐり部分がヨレてしまったのが残念。
