Kevlar® NoKnot Undercator Hover Sink Midge Tip Fly Line
A PVC-coated fly fishing line with a Kevlar core.
Think of it as a fly line that “parks” its tip just under the surface, so your buzzers and nymph teams track flat and calm instead of creeping deeper. A long floating head feeds into a short section that sinks at 2 IPS, then a tiny floating tip balances it out, creating a proper hover effect, and the visible tip becomes your subsurface strike indicator because any tick or draw shows immediately. Zero-stretch Kevlar backing and a Kevlar core transmit those signals fast, while the NoKnot join and reinforced welded loop keep the whole setup neat and dependable.
A 2' floating tip followed by a sinking section, balancing perfectly to create a steady 6" hover below the surface. The buoyant floating tip counteracts the sinking section, keeping the line neutrally suspended for precise, sensitive strike detection, ideal for subtle subsurface presentations.
Kevlar® NoKnot Undercator Hover Sink Midge Tip Fly Line
Deadly for targeting nymph-feeding fish and buzzer feeders near the surface, this Midge Tip line is unmatched in calm, clear waters. Hovering precisely 6 inches below, it teases nymph-feeding fish on midges and close-to-surface buzzers, offering dramatic, instant strike detection with minimal surface disruption for ultimate stealth.
Used this Midge Tip as an underwater indicator—caught trout left and right! The zero-stretch design makes every little take pop. Total game-changer!

Dave G.
"Seems so obvious now"
The fact it's one continuous Kevlar fly line and backing is just genius.
Warren C.
"Panic over"
I've got a 100% strong smooth connection so when a fish runs I just let it.
Joshua A.
"NoKnot has changed it for me"
I used to worry about the knot jamming in the rod guides. No more.
Henry L.
"No more expensive backing"
Basically it's like getting free gel spun backing, but better.
Don't take our word for it. Ask Dupont USA.
5 times stronger than steel.
Kevlar is used in the most demanding environments in the World. It has zero stretch which means that your casting gets a hit of steroids, the hook sets are instant and pound for pound your fly line is now 5 times stronger than steel. Because our core does not stretch during casting or fishing, our coatings don't crack.
It's not just our core that is bullet proof
Reinforced welded loop
Featuring a Kevlar core, our welded loops are already the strongest on the market. That wasn't enough for us, we went one step further and wrapped our welds in a micro thin film of protective tubing. Supple, strong and slim.
Cores of steel & coatings of glass.
We're not just a pretty face.
Our fly lines contain microscopic particles of 3M glass air microspheres. Every colour is chosen not just for it's optical qualities but also it's flight characteristics. Our R&D into pigment science informs our coating formulas in a way that has set us apart from the industry for the last 15 years.
NASA® approved.
Interesting Fact : When the Mars Pathfinder landed on the surface of Mars, ropes made of Kevlar® helped it to complete its 40-million-mile journey.
A Kevlar fly line will enhance any rod by any brand. Whether it's carbon, fibreglass, fast or slow, it will make your rod feel like it's on steroids.
Match the line rating to the rod rating. A Kevlar fly line weighs the same as a regular line. It just flies faster and further.
Just use a regular arbour knot, the same knot you would use for tying regular backing to your fly reel.
Kevlar® is very good at repelling water and drying. It is the strongest cord material per diameter in the World. It will not rot.
Regular backing will not be as strong as Kevlar®. We recommend you unwind your regular backing and load with NoKnot, the strongest backing and a seamless connection to your fly line.

So what is Kevlar® exactly?
I took this Midge Tip out on calm water, targeting buzzer feeders, and it was deadly—hooked multiple trout right near the surface. The line hovers perfectly, and I saw every take instantly!

Before this, there was no such thing as a tip that hovered, they all slowly sank
On a clear morning, I tested the Midge Tip’s 2' floating tip and sinking section design. Watching it hover perfectly at 6 inches, I was dialed into every subtle take. Within minutes, I had trout hitting emergers right below the surface—every strike was instant.
Sunray fly lines are the only fly lines with Kevlar® cores. Our Overhang Marker® has helped 80,000 fly fishers Worldwide cast more effectively. We invented 'micro-thin' fly lines in 2014 and our tapers are built on 45 years of fly casting experience.
Simple, call our customer services or email support@sunrayflyfish.com. We will send you a pre paid returns label and ask you whether you'd like a refund or replacement.
We offer a no none-sense 3 month money back guarantee if anything goes wrong with your line, whether it was your fault or ours.
We're not new to this. We formed in 2014 and we are the biggest direct to consumer fly fishing brand in the UK. We ship Worldwide and we get it there quickly.
I needed the fly line for a competition. I ordered on Friday and it was on my door matt Saturday morning, amazing.
I had confidence in the fact the core was made by Dupont and the coating 3M. I wasn't dissapointed. Wow!
I couldn't believe how quick it was delieverd. It felt like I had just placed the order and it was there! All the way from the UK in a matter of days.
Despite Brexit I took a chance ordering from this UK company. Yes, I had to pay taxes but it's the best fly line I have ever bought and it was cheaper than the American brands.
