Photoelectron is a special ceramic that uses the far-infrared energy emitted from the human body to warm the body to the core. By combining it with various materials, a more effective heat retention effect can be achieved. It also has the characteristic of improving the evaporation and quick-drying properties of moisture such as sweat.
The brushed back side is napped and, unlike normal brushing, the threads are entangled like sheep's wool to form a ball to prevent the threads from coming loose, creating a ball-like, uneven appearance.
The fabric is lighter than it looks, and feels comfortable to wear.
The stitching on the sides and underarms is curved for mobility.
The stitching is flat seamed to reduce contact with the skin.
"Gunze = Prevent E =" thread is used for sewing to suppress the generation of unpleasant static electricity, cling to the body, and reduce dust.
