[Product Details] Workman's popular "THERMOLITE Eco Mode Thermal Crew Neck" Perfect as an immediate-use mountaineering/outdoor inner layer! Weighing only 126g, it's an ultra-lightweight design, and the crew neck type makes it easy to layer, making it useful for everyday wear to本格登山. The THERMOLITE Eco Mode material has a hollow fiber structure that provides both excellent heat retention and sweat wicking (breathability). Even if you sweat, it won't feel sticky, and you can move comfortably. [Comparison with other brand materials] Highly recommended for serious mountaineers! "THERMOLITE Eco Mode," a representative material for high-performance active insulation, is similar to "Octa" and "Polartec Alpha Direct." These materials use a hollow structure and mesh knitting to exhibit heat retention, breathability, and quick-drying properties, and the common point is that they are less likely to get stuffy during activity. You can wear Workman's THERMOLITE Eco Mode comfortably!
