Redefining what thermal wear can be

Tailored for any body, any style, this versatile long sleeve tee combines warmth, antibacterial protection, and breathability, delivering comfort without compromising on style. Not just for winter—it’s your go-to layer for cool mornings in spring and fall, outdoor adventures, or daily wear. One top, wearable across three seasons.

Drawing inspiration from the principles of mountaineering layering, we’ve combined key elements—moisture-wicking, heat regulation, and outer protection—into a single thermal with a double-layer structure. 

We created BASE+ base layer with the vision to revolutionize the concept of everyday wear and layering clothing. Unlike conventional thermals, BASE+ base layer can cut down your apparel, keeping you comfy and active from fall to spring, from outdoor to indoor.

Base+ thermal is crafted using a special fabric with a fiber structure similar to Merino wool, offering a perfect blend of moisture-wicking, antimicrobial properties, and thermal regulation that enhances blood flow, reducing muscle fatigue.

Softer feel, skin-friendly comfort, and elevated breathability & moisture control.

Expertly engineered to combine warmth, antibacterial freshness, and breathable performance, Base+ 2.0 brings together the best of comfort and style. It’s more than just winterwear—perfect for layering during crisp mornings in spring and fall, ideal for travel, or styled solo for effortless everyday looks. Compared to conventional thermal tops, it offers enhanced comfort and breathability—function meets fashion in a piece that’s as versatile as it is good-looking.

• Enhanced Quality｜Ultra-soft and skin-friendly for a smooth, irritation-free fit
• Triple Performance｜Heat-retention, moisture-wicking, and odor-resistant antibacterial properties
• Lightweight & Durable｜Slim, breathable and comfortable even after long wear
• Everyday Versatility｜Made for workdays, adventures, and cozy indoor moments

A New Standard for Everyday Comfort

Built on the trusted DNA of the original Base+, the NEW Base+ 2.0 is smarter, softer, and more breathable than ever. With added stretch, a smoother feel, and MicroBan® antibacterial tech, it’s designed to keep you fresh and comfortable across seasons. Inside, ceramic micro-brushing creates a light fleece texture for enhanced softness and sweat control—a true evolution in thermal wear.

Sustain Thermo Tech 

The core of SUSTAIN THERMO TECH lies in preventing heat from escaping. Fine fibers trap body heat, while the double-layer structure creates an insulating space within the shirt that retains warmth, keeping you snug and flexible.

Far-infrared Ray Support

Since shoulders and elbow joints tend to cool down the fastest and warm up the slowest, we’ve added an extra far-infrared layer to these areas for enhanced protection improving circulation and helping relax tight shoulder muscles.

Silver Nano Technology

The base layer’s excellent wicking ability keeps the fabric dry, inhibiting odor-causing factors. On top of that, we’ve applied Silver Nano technology to the outer fabric for added freshness.
