Alison Gray –
Used this bag during a week-long fishing trip in a rainy canyon. It stayed completely dry even when I dropped it in a stream. The zipper is smooth and the organization helps me keep everything accessible. No leaks, no worries. Perfect for unpredictable weather.
Joan Quinn –
Felt solid and reliable during a trip to a saltwater flat. My camera and fly boxes stayed dry. The layout is simple but effective. A bit heavy for short hikes, but worth it for serious anglers.
