Why Choose C-one
Is it time to stop choosing your base layer
as an afterthought?
Urban refinement and outdoor-level functionality.
Two qualities that may seem opposite, brought together in a single piece.
That is the base layer for adults proposed by C-one.
Why Merino Wool Works Like Natural Climate Control
What synthetic fibers cannot easily do
Say goodbye to uncomfortable sweat chill in winter
You sweat on a heated train or in the office, then suddenly feel cold the moment you step outside.
This is one of the common issues with synthetic thermal innerwear that absorbs moisture and generates heat.
C-one’s Merino wool is different.
Through its natural moisture-regulating function, it releases sweat as vapor and helps keep the inside of your clothing at a comfortable humidity level.
Experience a layer that feels better the longer it touches your skin.
For dry or sensitive skin
- Exceptionally soft, non-prickly feel
- Less prone to static electricity
- Natural antibacterial and odor-resistant properties
- Easy care, machine washable
Around 15,000 yen per piece.
Here is why.
This is a different level from ordinary wool.
C-one uses ultra-fine Super 100's class fibers, measuring 18.5 microns, the same grade often used in premium suiting fabrics.
The fineness is about one-fifth the thickness of a human hair.
That is why it feels smooth even when worn directly against the skin, without the prickliness often associated with wool, while offering a cashmere-like softness and subtle luster.
We have also removed the chest logos and sporty panel designs often seen in outdoor-brand apparel.
That is why it looks beautiful under a jacket and works naturally as refined clothing for adults in the city.
Bring refined quality
to your jacket style.
Move beyond wearing what everyone else wears.
Have you ever felt awkward after realizing someone else in town was wearing the same mass-market or outdoor-brand inner layer?
C-one is a choice for adults that stands apart from mass-produced clothing.
Its refined sheen and carefully designed neckline allow you to look composed even when you take off your jacket and wear it on its own.
Not clothing that everyone wears, but clothing that says something about you.
That quiet sense of confidence is also part of C-one’s function.
Let your skin decide the answer.
If this is your first time trying C-one, start with the Basic T-shirt or Mock Neck.
Once you experience the comfort, it may become difficult to go back to ordinary innerwear.
