Tough casual-cool outdoor gear for nature lovers eager to get off the beaten path!
Introducing the PRG-340L, 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.
Based on the PRG-340 with its dual-layer LCD, compass graphics appear on the top layer, while the bottom layer offers a large display of the time and various measurements, for an even easier read. The slimmed down LCD minimizes bulk, even while advancing functionality.
The Triple Sensor delivers compass bearing, barometric pressure, altitude, and temperature readings, and the Tough Solar system keeps you charged. The subdued color scheme of coyote brown is complemented by a faux leather band for a classic look that blends seamlessly with outdoor settings and everyday wear alike. The band is treated with flame retardant to hold up even when hit by sparks from cooking or campfires.
