120g/m² synthetic fiber insulated rain pants for easy maintenance. These insulated rain pants combine easy-to-maintain synthetic fiber insulation with a GORE-TEX outer layer. An ideal item for thermal layering, providing warmth and a light feel with fewer layers, the main insulation has been increased by 150% compared to the previous RB-01PU model. Considering the movements of fishing, 120g/m² and 100g/m² insulation are strategically placed in areas prone to feeling cold and areas requiring mobility, ensuring ease of movement.
