Wanda Cameron –
This jacket performs well in rainy conditions. The GORE-TEX® Pro fabric keeps me dry even when I’m moving around in wet environments. The chest pockets are easy to use and the handwarmer pockets are handy for cold mornings. The hood is adjustable and stays in place during long hours on the water.
Elizabeth Mills –
I’ve used this jacket for several trips to the lake and it holds up well. The storage features are practical, especially the stowable fly patch tool. The only minor issue is the zipper on the handwarmer pockets can be a bit stiff when opening, but it’s not a major concern.
Molly McDonald –
Excellent build quality and weather resistance. The 3-point hood fits well and stays secure. The internal stretch pocket keeps my phone safe and the chest storage is organized. I appreciate the thoughtful design for fishing on foot or from a boat.
