Thanks to our patented "polymer dual-layer structure," this garment provides the feeling of being in a "high-temperature sauna" only on the inside, where it touches your skin. It easily promotes perspiration. The inner layer uses a special polymer material, so even though you're drenched in sweat on the inside, the quick-drying outer material keeps you feeling fresh and dry. Because it's a sealed space, odors are also contained. With its simple, modern design, it can be worn stylishly as an inner layer or as a single piece of everyday wear. Experience the "Inner Sauna" with our Patented Dual-Layer Technology. Our unique polymer lining triggers intense sweating where it matters most, while the moisture-wicking outer shell keeps you looking fresh and dry. No sweat marks, no odors—just results. Designed with a modern, minimalist aesthetic, it’s the perfect fusion of high-performance tech and everyday style. #HEATTRAP #ヒートラップ #サウナシャツ
