■Product Details.
Warm CoreS T-Shirt
— Looks ordinary, but has a warm heart —

During the transitional seasons, when I was hiking or running in the mountains, I’ve had trouble with my stomach getting cold.
I know that tucking my top into my pants keeps me warm. But that look just doesn’t suit my style.
On the other hand, if I put on another layer underneath, the upper body and underarms end up unnecessarily double-layered, and sometimes it gets too hot.
――Wondering if there was a way to address that slight discomfort, I came up with the idea of making only the lower part of the abdomen a double-layered structure.
When I shared that idea with the designer behind Axie's "Ryo" line, the result was the "Haramaki T-shirt."

Building on that concept, Gradation has now brought the Warm Core S TEE to life as a long-sleeve T-shirt.

Features a double-layered design on the inside (which I’ve dubbed the “belly-warmer structure”). By making only the lower part of the abdomen double-layered, you can tuck the inner layer into your pants to keep your core warm when it’s cold, while the outer layer remains outside your pants, so it looks just like a regular long-sleeve T-shirt.

In addition, the wide silhouette at the upper arms helps reduce heat buildup under the arms, creating a sensation similar to the warmth of a traditional Japanese belly wrap—that’s Warm Core.

A warmth that lies unseen gently wraps around your core. This is a new base layer born from the fusion of "Ryo"’s wisdom and Gradation’s philosophy—a garment that **“belongs nowhere yet fits in anywhere.”**

《Background》
During the transitional seasons, when I was hiking or running in the mountains, I’ve had trouble with my stomach getting cold.
I know that tucking my top into my pants keeps me warm. But that look just doesn’t suit my style.
On the other hand, if I put on another layer underneath, the upper body and underarms end up unnecessarily double-layered, and sometimes it gets too hot.
――Wondering if there was a way to address that slight discomfort, I came up with the idea of making only the lower part of the abdomen a double-layered structure.
When I shared that idea with the designer behind Axie's "Ryo" line, the result was the "Haramaki T-shirt."
Eventually, that product reached the end of its lifecycle, but the comfort provided by its design remains vivid in my memory to this day.
"I want to bring this idea to life again."
With that in mind, we created the Warm Core series as a new addition to the Gradation line.

"The Meaning Behind the Name"
Warm Core—literally, “warm core.”
While it refers to a design that warms the core, it also carries a slightly stronger emphasis on the idea that "true warmth resides in the unseen parts."
On the surface, it looks like a perfectly ordinary long-sleeve T-shirt.
But inside, there is a mechanism that operates quietly.
It’s a mindset that values “personal comfort” at its core, rather than flashiness or making a statement.
Choose a balance that feels right to you, not just to fit into a certain category.
Warm Core was born at the intersection of freedom and functionality—a hallmark of Gradation.
