Garmin Enduro 3 vs Suunto Vertical Solar

The Garmin Enduro 3 is the flagship option, boasting an incredible 90 days of battery life in smartwatch mode with solar charging. In contrast, the Suunto Vertical Solar offers a solid 60 days, making it a strong contender but not quite as impressive as Garmin's offering. In real-world use, the Garmin's ultra-lightweight design at just 2.22 oz makes it perfect for long adventures, while the Suunto's robust build is excellent for rugged conditions. However, if you're after exceptional GPS tracking, the Enduro 3 crushes the competition with up to 320 hours compared to Suunto's 85 hours. That's a game-changer for serious athletes and adventurers alike.
