I haven't had a chance to use this yet but I am looking foreward to it, I'm tired of getting flies hooked in fleece patches and struggling to get them out. Product looks to be well made for the job and it can be put anywhere you want,this might seem trivial but vests are geared to right handers so the fly patch is always on the wrong side, now I can put it where I want it.
Great place to temporarily hold your flies, while you switch things up at that mountain lake. I usually have 3 to 5 flies waiting for me on the patch. Also, this lets them dry, so they can be put away later.
