Tough casual-cool outdoor gear for nature lovers eager to get off the beaten path! Introducing the PRG-340B, a solar-powered PRO TREK with key components made of bio-based resin, a material expected to help reduce environmental impact. Packed with advanced features and total practicality, this PRO TREK is ready for every outdoor setting. The Triple Sensor delivers compass bearing, barometric pressure, altitude, and temperature readings, and the Tough Solar system keeps you charged. The watch features key components made with bio-based resin and a cloth band made of CASTLON®, treated with a flame retardant finish. CASTLON is a 100% plant-derived Nylon 11 fiber produced using castor oil plants. This carbon-neutral material not only helps reduce environmental impact, but is also stronger and lighter with better wear resistance, chemical resistance, and flexibility at low temperatures than the conventional Nylon 6.
