### ⭐⭐⭐⭐⭐ Good stuff
*by I***C on October 17, 2020*

It's fly line backing. If we're being honest, unless you fish saltwater, most folks won't catch a fish big enough to peel off enough line to ever see the fly line backing on the reel! Even if you do fish salt water and/or do catch fish big enough to peel off enough line to see the backing of your reel, this stuff will be more than sufficient! That aside, this is good fly line backing with some cool colors not found anywhere else to make fly line and reel colors compliment each other. It's equally as good as any other fly line backing by any other company that I've ever used and at a decent price point too. Plus, 100+ yards per spool is more than enough backing for most reels too. I've bought several spools of this stuff for my reels in different colors and I'm very satisfied with it. This stuff does fray a little after it's been cut, but so does every fly line backing that I've ever used. A little touch from a lighter to the end solves that issue. Don't let a couple of negative comments about fraying line detour from this product... I haven't had any problems with any of the spools I've bought and I think it's every bit as good as any of the big name brand manufacturers of fly line backing currently on the market, because I have and have used those too.
