Orvis Hydros SL Fly Reel Review

Please remember that there are no ads on this page and 100% of our funding comes from your purchases, so if you find this review to be informative, please help us keep the reviews coming by purchasing your next fly reel from us.

Back in our 2015 5-weight shootout, we noted that the Hydros LA was a solid reel, but it didn’t really fit into the Orvis line up well. It was a little too expensive and didn’t offer any real advantages over the Access Mid-Arbor. Orvis took that feedback to heart and came out with the Orvis Hydros SL a few years later.

Since they had essentially fixed all of our complaints, we’ve been selling tons of these and they’ve been one of our top sellers. Until today, however, we haven’t had a chance to do a proper review of this reel. I can tell you, it does NOT disappoint.

8-Weight Shootout Full Results

Weight

7.7 ounces. Much lighter than any reel with this much power.

Drag

The drag on the Hydros SL was the best in our test. It not only bests its big brother the Mirage (which is also great), but it beats out reels like Hatch, Abel, and Nautilus. Am I convinced that this is a truly sealed reel? No. However, from what we are able to measure in this test, the Hydros comes out on top. Here’s why:

First, the Hydros has a massive amount of drag – 14lbs at the top end. However, you can’t quite use all of it, so when we backed it off ¼ turn, it still maintains over 12lbs, which puts it second only to the Hardy Fortuna. Next, it’s got a super linear drag, so you can really adjust it to your specifications. It retains almost 50% at the halfway mark with nearly 7lbs. Finally, at the bottom, Orvis keeps you from free-spooling with .2lbs.

Sound

Like the Mirage, there’s nothing special here. It’s not bad, but it’s fairly muted in both directions.

Spool & Retrieval Rate

The spool on the Hydros is also epic. It takes 3rd place with a retrieve of over 10” per turn and it does that with a nice narrow spool (under 1”). The only area where the Hydros doesn’t dominate is volume. It’s got plenty of capacity for standard 8-weight lines, but you’ll want to go for a gel-spun if you’re going to put a thicker line on.

Looks & Ergonomics

We tested the Citron version of the reel, which I personally think looks pretty good, but it also comes in a more toned down grey. It’s a good looking reel, but it lacks the finer touches of some of the higher end reels.

While the looks of the SL are fine, the ergonomics are not. Ok, the handle is ok, but the drag knob is horrible. It’s way too small and someone had the not-so-great idea of adding an indent for your thumb. It’s sharp, it doesn’t work well. Too bad. This alone takes the reel out of contention for me. It’s that bad.

Finish and durability

The finish on the Hydros is also excellent. Even in the green color, it’s hard to find the scuffs on most of the reel. Its lighter weight helped too.

Warranty

Lifetime to the original owner + $30.

Price: $239

Conclusion

Several weeks ago I was asked by a customer which saltwater reel I would recommend that “wouldn’t break the bank” – since it came out, my answer has always been the Hydros SL. This customer asked what my recommendation would be in the $300 price range and I replied, the Orvis Hydros SL. What about the $400 price range? The Hydros SL. I stand by that statement.

Simply put, this reel has the best drag in the test. If we did a “performance only” category, this reel would have scored the highest. At a $240 price point, it’s so much better than anything else out there that you’d have to drop 10 places to get to a reel that’s in the $300 price point.

Pros

  • From a performance standpoint, there’s nothing better.

Cons

  • Missing some of the high end features
  • Horrible drag knob

He’s built his reputation by putting gear to the ultimate test in the world’s most unforgiving fisheries. With fishing stamps from over 22 countries and 17+ states, Ben’s passport is a roadmap of bucket list angling—from landing a 25lb Golden Dorado in Bolivia and 150lb Arapaima in Guyana to sight-casting for Roosterfish off the beaches in Baja. Whether it’s battling 60+mph winds to land a 20lb Rainbow at Jurassic Lake or a full day of casting 8in streamers in Mongolia, Ben has spent decades ensuring his gear performs when a trip of a lifetime is on the line.

At Trident, Ben serves as the lead gear geek, specializing in the deep-dive mechanics of rods, reels, and lines. Over the past 15 years, he's reviewed 250+ fly rods and 150+ fly reels and is likely one of the most prolific rod reviewers in the world. But he doesn't just curate the catalog; he scrutinizes every taper and drag system through the lens of a traveling angler who knows what it's like to have gear fail a thousand miles from home. For Ben, the mission is simple: leverage his experience across nearly 100 species to ensure that when you head into the wild, you’re equipped with gear that has been vetted by someone who has actually been there.
