    The day you need the RIO Dacron Fly Line Backing will be a good day, because that means the fish of a lifetime just slurped your fly and is making an epic run. The strong braided backing is thin but still knots easily and allows you to make blind splice loops.

    20lbs Ideal for 8 to 10 Weight Rigs

    • Familiarity: I've put it through the wringer

    Most of the time, backing is just a spacer for your reel to take up space and give you better turning radius on reel cranks. Up to 12 lbs backing test is good for trout, but you will want more when you get into salt or bigger freshwater gamefish. 20lbs test is ideal from 8 to 10 weight rigs and then step up to 30lbs test backing once you are at 11 weight and above going for offshore and big inshore fish like tarpon.

    Simple Yet Effective

    • Familiarity: I've put it through the wringer

    I have put Rio backing on all of my rods and reels from my 3-6wts in the 20lb. I have never had any issue with breakage and the knots have always held tight to the spool. Also, if you are having issues where your backing meets your fly line, try not to pull extremely tight on the knot, but rather finesse the knot together. Sometimes hammering down on your backing to fy line knot causes the backing to pierce through the gel coating and into the core of the fly line eventually leading to breaks.

    Rio 30lb backing

    • Familiarity: I've put it through the wringer

    I bought this in orange color and put on my Sage spectrum max reel. Looks awesome and takes up the righ amount of space. I havent had a fish take the line out to the backing but i'm sure its strong enough.

    Spend less time reeling

      I wish this review as about the huge fish that ripped all the line from my reel so fast it scorched my hand, but the truth is backing is mostly about taking up some space and volume on the arbor so that you can reel in more line with each rotation. Less important with a large-arbor reel, but every bit helps. This spooled and tied great. Up to the job.

      Does it's job!

      • Familiarity: I've used it several times

      I have a 100 yards of 30 lb orange on my Rapid Ross reel. It fits on the reel with plenty of room for the floating line. It looks good and gives me a lot of confidence that I will have enough line for those big pigs lurking out there who are going to make a run for it.

      Hold it down

        Holds the line to your spool just like you need it to! I went with the 30yd option and feel like it's perfect for my 9'5" TFO rod and my Sage 2200 reel. Basic - but you'll want to make sure you can rely on this backing for when that monster finally takes your fly....

        Safety on!

        • Familiarity: I've used it several times

        I bought this for my 3 weight Sage 3200 reel. Only needed about 50 yards, then the 80 foot fly line filled the spool. Super easy to know when I am getting close to the end of the fly line with the bright orange color, have NOT had to rely on it yet but glad that it's there.

        My go to backing

        • Familiarity: I've put it through the wringer

        I have this on all of my reels and its never failed. Lets be honest though, you rarely rely on your backing in day to day fishing. The several times I've needed extra run, its done its job and its very distinguishable from my float line.

        Great value backing

        • Familiarity: I gave it as a gift but have feedback to share

        Rio's backing is excellent and good at the price point. The color is very distinguishable in the Chartreuse and would buy it again in the future.

        Can't Go Wrong With Simple

          I'm not sure how you could go wrong with this backing. It is super simple and easy to add to any reel and the Chartreuse and Orange makes it look pretty cool. It's highly visible so if you do hook into something big enough, you can see it when needed.

          Used on every reel

          • Familiarity: I've put it through the wringer

          I have this on everything from a 3 weight reel I use on small streams to a 10 weight I use for pike and saltwater. While it is probably overkill on the small reels as most fish I would catch are not capable of taking me into the backing, it is nice to add some diameter to the spool so the fly line doesn't get wound so tight.

          Looks nice, goes on easy.

          • Familiarity: I've used it several times

          Figured it was time to switch my backing out since it had been a few years. Haven't had a trout test it yet, but it appears to be strong, and the orange color looks great once it's spooled up.

          Industry Standard

          • Familiarity: I've put it through the wringer

          Awesome Dacron backing that holds up "reely" well. Use a lil UV Knot Sense from LOON when tying the knots to give it just a lil extra security (though it's not necessary). Great color choices. I've used on lots of trout ranging from 6-10lb trout and on lots of 20-30lb carp and it holds up plenty fine!

          No Complaints

          • Familiarity: I've put it through the wringer

          Other than I haven’t caught a fish large enough or that has fought hard enough to get into my backing. Its solid, I have the Sage 4200 Series Fly Reel in a ¾ weight and I didn’t use all of the backing. I still had some left over. I actually think I put on a tad too much since my line starts catching on the reel when I reel the line in all the way. However, that is user error. Rio is the best, I always know I am getting top of the line quality with them. I also purchased the Chartreuse, 20lb/100yd. If you have a lower weight rod/reel combo you wont need anymore than that.


            Love this backing. I use this on my 8 weight (30 lb) and it's done fine. I've only gotten into my backing a few times and I haven't had any worry about it. I've never used any other backing but Rio's and I guess I've never had an issue so I just stick to what I know works.

            You won't always need it.

              But you'll be glad to have it when you do. Good stuff, bright yellow and easy to see. Depending on the reel you probably won?t use all 100?. Great to have in case you get a runner.
