Hackles and Capes Explained: How to Choose the Right Fly Tying Feathers

By Ben Worley - 8 minute read

For many fly tyers, hackles and capes are among the first materials to cause a little confusion. There are dry fly capes, saddles, hen hackles, game-bird feathers and modern synthetic hackles, all intended to do different jobs. The good news is that once you understand how each type behaves, choosing the right material becomes much easier.

The right feather can help a dry fly sit correctly on the surface, give a wet fly natural movement or add shape and attraction to a streamer. Many years ago Lindsay Simpson helpfully guided me in how to select the best natural feathers and where to source them and it changed my fly presentation and catch rate immediately. I hope to pass some of this experience on while explaining what hackles, capes and saddles are, how they differ and what to look for when choosing them.

Why Hackles Matter in Fly Tying

Hackle is not simply decoration. Depending on the feather and how it is tied, it can provide flotation, movement, profile, silhouette and stability. A stiff dry fly hackle helps support a fly on the surface film, while a soft feather moves and pulses below it.

When selecting hackle, think first about what you need the finished fly to do. A feather that is perfect for a dry fly may be completely wrong for a spider or streamer.

What Is a Fly Tying Hackle?

In fly tying, the word hackle generally refers to a feather used either by winding it around the hook or tying it in as part of the fly. Most traditional hackles come from roosters, hens or game birds, although synthetic hackles are also widely used in modern patterns such as the Upavon Straggle Hackles I design and manufacture.

Hackles are commonly used to create:

• Flotation and support on dry flies
• Legs and movement on nymphs and wet flies
• Body shape and silhouette
• Movement and flash in streamers and lures
• Collars, throats and trigger points

What Is a Fly Tying Cape?

A cape is the feathered skin taken from the neck area of a bird. Its main advantage is the wide range of feather sizes it contains. A good dry fly cape may provide feathers suitable for larger mayflies at one end and tiny midge patterns at the other.

This makes a cape an excellent all-round choice for anyone who ties a varied selection of flies. It is often the most versatile first purchase for a new dry fly tyer.

When to Choose a Cape

• You tie several different hook sizes
• You want one versatile source of dry fly hackle
• You tie mixed trout patterns rather than one repeated size
• You need shorter feathers with a broad range of barb lengths

What Is a Saddle Hackle?

A saddle comes from the back of the bird. Saddle feathers are generally longer than cape feathers and are often more consistent in size along their length. High-quality genetic saddles can sometimes tie several flies from a single feather.

Saddles are particularly useful when tying batches of the same pattern because the feathers are long, efficient and consistently sized.

When to Choose a Saddle

• You regularly tie the same fly size
• You tie streamers, Woolly Buggers or saltwater flies
• You want long feathers for palmering
• You tie flies in larger quantities

Cape vs Saddle: What Is the Difference?

Dry Fly Hackle vs Soft Hackle

Dry Fly Hackle

Dry fly hackle is usually taken from a rooster and is selected for stiff, straight fibres with very little webbing. Those fibres help support the fly and spread its weight across the surface film.

Good dry fly hackle should have:

• Stiff and resilient barbs
• Minimal webbing
• A thin, flexible stem
• Consistent barb length
• Enough usable feather above the fluffy base

Soft Hackle

Soft hackles are chosen for movement rather than flotation. Hen, partridge, grouse and starling feathers are popular because their fibres collapse, open and pulse naturally in the current.

They are especially effective on traditional spiders, wet flies, emergers and nymph collars. In these patterns, a sparse turn or two is often more effective than a dense collar. Soft hackle are fantastic imitations for legs and prove very effective as collars for Grayling bugs.

What Does Genetic Hackle Mean?

Genetic hackle comes from birds selectively bred to produce feathers suited specifically to fly tying. Over generations, breeders have developed birds with longer usable feathers, finer stems, more consistent barb lengths and better dry fly properties.

Genetic does not automatically mean that every feather is suitable for every purpose. You should still choose a cape or saddle according to the patterns and sizes you tie most often.

What to Look For When Choosing Hackles and Capes

Feather Size and Barb Length

The barb length determines the effective hackle size. Before buying, consider the hook sizes you use most often. A cape offers breadth, while a saddle usually offers more feathers within a narrower size range. A hackle gauge, such as the Upavon Bubble Fish Tool Bar & Hackle Gauge, or Stonfo Hackle Gauge makes matching feather size to hook size much easier.

Stiffness

For dry flies, the fibres should spring back when gently pressed. Soft, webby fibres are better for wet flies and moving patterns. Neither is inherently better; they simply serve different purposes.

Webbing

Webbing is the softer, denser section near the base and centre of a feather. Minimal webbing is desirable for delicate dry flies. More webbing adds colour, bulk and movement to streamers and subsurface patterns.

Stem Quality

A thin, flexible stem is easier to wind and less likely to twist or split. Very thick or brittle stems can make neat wraps difficult, particularly on small hooks.

Feather Density and Usable Length

A higher-quality skin normally contains more usable feathers and fewer gaps or damaged areas. Consider value by the number of flies you can tie, not simply the purchase price.

Natural and Dyed Colour

Natural shades such as grizzly, brown, ginger and dun are useful across many traditional patterns. Dyed hackles add consistency and strong trigger colours. Look for even dyeing without losing the feather's natural sheen and movement.

Which Hackle Should You Use for Different Flies?

Where Synthetic Straggle Hackle Fits In

Synthetic straggle hackle is not a substitute for every natural feather, but it is extremely useful for stillwater flies, lures, nymphs and modern attractor patterns. It gives consistent fibre length, colour and flash, and can be wound as a body or collar.

I've been designing and machine manufacturing straggle hackles for Upavon for a few years now and can honestly say they rarely imitate natural feathers. However, they are great to complement naturals or provide more vivid and attractive colours - they can be very effective and shouldn't be ignored. Straggle Hackles are predominently used for wet flies and come in sizes ranging from 4-30mm in width, are uniform in size and can be a solid colour or combine colours with irridescent flash with hundreds of possible combinations and colours.

Upavon's award winning synthetic hackle options include Pure Colour Straggle Hackle, UV Boosted Straggle Hackle, Camo Straggle Hackle and Blue Flash Damsel Straggle Hackle if you wish to see some examples.

Which Hackle Is Best for Beginners?

For someone beginning to tie traditional trout flies, a good-quality dry fly cape is usually the most practical starting point because it covers a broad range of hook sizes. Add a soft hen or game-bird skin for wet flies, then consider a saddle once you know which repeated sizes or streamer styles you tie most often.

It is generally better to buy one useful, good-quality skin than several cheap capes with brittle stems and few usable feathers.

Frequently Asked Questions

What is the difference between a cape and a saddle?

A cape comes from the neck and offers a broad range of feather sizes. A saddle comes from the back and offers longer feathers that are usually more consistent in size.

Which hackle floats best?

Fine genetic rooster hackle with stiff fibres and minimal webbing is normally the best choice for flotation. Correct sizing, fly proportions and floatant also affect how well the finished fly sits.

Can one cape tie several hook sizes?

Yes. That is one of the main benefits of a cape. A quality cape can provide feathers for a wide range of hook sizes, although the exact range varies by grade and individual skin.

When should I use soft hackle?

Use soft hackle when you want movement below the surface, particularly on spiders, wet flies, emergers and nymph collars.

How do I know what size hackle to use?

Use a hackle gauge or compare the barb length with the hook gape. The correct proportion depends on the pattern, but measuring consistently helps produce balanced flies.

Summary

Choosing hackles and capes becomes much simpler when you start with the job the feather needs to do. Stiff, low-web rooster hackle supports dry flies; soft feathers create movement below the surface; capes provide versatility; and saddles provide length and consistency. Take time to examine the stem, barb stiffness, webbing, usable feather length and size range. Better-suited materials make tying easier and produce flies that look and fish more effectively.
