I’ve used this sling pack on multiple fishing trips and it holds up well in wet conditions. The material feels sturdy and the rotation feature makes accessing my flies and tools fast and convenient. It’s lighter than a full pack and doesn’t add much bulk to my gear.
Jasmine Lyman –
The water resistance is better than the old model, especially when I’m fishing near streams. The fly box fits snugly and the strap stays in place even when I’m moving around. A solid upgrade for daily river use.
