Foam core, thermoformed, Gen 3, Gen 4: what pickleball paddle jargon actually means

Buy a pickleball paddle in 2026 and you are not really buying a paddle. You are buying a paragraph. Thermoformed unibody. T700 raw carbon. Foam core. Microporous polymer. Gen 4. Dual-zone power ring. Underneath all of it sits a stiff face bonded to a light core with a handle on the end.

Some of that language — foam core, thermoformed, carbon fibre — describes something real and worth paying for. Some describes a manufacturing process that genuinely changes how a paddle plays. And some of it is a number a marketing department chose because the previous number was taken.

Here is the plain-English version.

The short answer

Gen 3 paddles are built around a polypropylene honeycomb core — usually thermoformed, often with foam packed into the perimeter walls — while Gen 4 paddles replace that honeycomb with engineered foam, either partly or entirely. Neither term is defined by any governing body: they are manufacturer marketing labels, brands draw the lines in different places, and the construction spec on the product page tells you far more than the generation number on the box.

Nobody agrees where the generations start

The generation labels came from the industry, not a rules body. USA Pickleball and the UPA certify whether a paddle is legal for sanctioned play. Neither certifies whether it is a "Gen 3".

Which is how you get this. The Luzz Glider 2026 is sold as a Gen 3 paddle, and its core is polypropylene honeycomb — the same material other brands file under their oldest construction. The Luzz Cannon carries no generation at all, just "thermoformed". The two Luzz Pro 4 paddles are Gen 4. Three conventions, one brand.

Loosely, across the category, the terms get used something like this:

• Gen 1 — cold-pressed. Face glued to a honeycomb core, edges held by an edge guard.
• Gen 2 — thermoformed unibody, foam injected into the perimeter walls.
• Gen 3 — brands start adding something to the core: extra foam layers, propulsion inserts, kinetic elements.
• Gen 4 — the honeycomb comes out and engineered foam goes in.

Treat that as folklore, not a standard. Two paddles with the same generation number can be built completely differently.

The core: honeycomb, foam-filled, full foam

The core is most of the paddle by volume and most of what you feel.

Polypropylene honeycomb

Thin plastic cells stood on end between two faces. Light, consistent, very well understood. Honeycomb feels crisp and slightly hollow — the ball leaves the face quickly and the core does little to hold onto it. It is not old-fashioned; it is the most predictable material in the category, which is why it survives. The Luzz Glider 2026 is a 16mm honeycomb paddle at $189, and Luzz call it Gen 3.

Foam in the walls versus foam in the core

Two different things sold in similar language, and conflating them is the most common mistake buyers make.

Foam in the walls means foam injected around the perimeter of an otherwise honeycomb core, stiffening the edges so off-centre hits lose less energy. The core is still honeycomb.

Foam in the core means honeycomb has been removed and replaced. The Luzz Cannon is the clear example: 8mm of polypropylene honeycomb plus an enlarged foam layer, 16mm total. Half the core is foam, at $175.

Full foam

Remove the honeycomb entirely. This is what "Gen 4" points at.

Foam compresses on impact and springs back. The ball sits on the face marginally longer, which is where the plusher feel and the added spin potential come from, and the sweet spot spreads rather than sitting in one hot patch. The Luzz Pro 4 Inferno uses a microporous polymer (MPP) foam core. The Luzz Pro 4 Tornazo uses a PEBAZ™ dual-layer elastic core built on PEBA, the super-foam family used in elite running shoes.

Now the part nobody selling a foam paddle leads with. Foam cores can go dead. Foam takes a compression cycle every time you hit a ball, and early foam paddles developed a reputation for softening — losing rebound over months of regular play. The paddle doesn't crack. It gets dull, and one day your drives stop landing deep.

Newer formulations answer that directly. Luzz publish a density of 65–70 kg/m³ and a figure of 1.2 MPa for the Inferno's core, and describe it as crush-resistant. They do not publish what test the 1.2 MPa figure comes from, and we have not put one on a rig ourselves. What we can point at is the one-year warranty on both Pro 4 paddles — the number that costs the manufacturer something.

Foam is the most interesting material in the category and the one with the least long-term data. Both are true.

Thermoforming, and the mess it made

Thermoforming means the paddle is pressed and cured as a single piece under heat and pressure, with the carbon skin wrapped around the perimeter rather than glued to a separate edge. Unibody. Foam is typically injected into those walls at the same time.

Why it took over: a stiff, continuous perimeter loses less energy on off-centre contact. The effective sweet spot grows and the ball comes off faster from the top corners. The Cannon's U-shaped carbon fibre matrix and 3K carbon protection block are that idea, executed one particular way.

And the honest part. Thermoformed paddles are also where the delamination controversy of the Gen-3 era came from. When the face separates from the core, the paddle develops a trampoline effect — it gets more powerful, past what it was certified at, and then it dies. Players noticed. Some noticed and kept playing. Governing bodies tightened how paddles are tested, and manufacturers changed adhesives and processes. It is far less common in current builds than it was.

The lesson worth keeping: "thermoformed" tells you how a paddle was made. It tells you nothing about whether it will still be that paddle in eighteen months.

The face: carbon fibre, T700, and what spin really is

Nearly every serious paddle now has a carbon fibre face. "Raw" carbon means unpainted — the weave texture is left exposed rather than sealed under clearcoat. T700 is a fibre grade; it describes the carbon filament, not the paddle.

Then the surface treatments. The Glider carries a 984-Aero™ grit coating. The Tornazo uses a 3D grooved carbon weave. The Cannon runs a T700 raw carbon friction surface. Three ways of asking one question: how hard does this face grab the ball?

Because that is what spin is. Spin comes from surface friction and dwell time. The face needs texture to bite the ball; the core needs to hold the ball on the face long enough for that bite to matter. Which is exactly why foam cores and gritty faces get sold together — they attack the same variable from two ends.

One caveat every honest retailer should say out loud: all legal surfaces wear. Every gritty face loses grit. A two-year-old paddle does not spin like a new one, whatever it cost. If spin is what you're chasing, the spin paddles collection is the place to start.

The numbers that actually matter

Most paddle specs are noise. Four aren't.

Swing weight — how heavy the paddle feels while you swing it, not on the scales. Lower means quicker hands at the kitchen line and faster resets. Higher means more plough-through and more depth on drives, and a paddle that punishes you when a hands battle starts. Across the four Luzz paddles that runs from 111 on the Glider to 122 on the Tornazo. Eleven points is not a rounding error.

Twist weight — resistance to the head twisting when you miss the centre. Higher is more forgiving. The Glider sits at 6.4, the other three at 6.2.

Static weight — and here is the point. All four weigh between 224.8g and 225.1g. Three hundred milligrams apart. It is the number every product page leads with, and it tells you almost nothing.

Core thickness — 14mm versus 16mm. A 16mm core gives more dwell, softer feel, more control. A 14mm core is stiffer and poppier off the face with a smaller margin for error. Every paddle here is a 16mm pickleball paddle, which reflects where the category has landed for all-court play.

Then shape, which deserves a warning. The Glider is sold as a hybrid, the other three as elongated. All four are 19.00cm wide. The Glider is 41.50cm long with a 13.49cm handle; the elongated three are 42.01cm with a 14.02cm handle. Do the subtraction and the hitting surface is within a fraction of a millimetre of identical. The entire shape difference is roughly five millimetres of handle.

Where you feel it is the swing weight: 111 against 119–122. The label said shape. The balance said otherwise. If you'd rather shop by outcome than by spec, that's what the control paddles and power paddles collections are for.

How this maps to what we stock

Luzz is the illustration here for one reason: a single brand happens to span every construction above, which almost nothing else in the paddle range does.

All four appear on the UPA's approved-paddle list — the Pro 4 pair as UPA-A. Both Pro 4 paddles carry a one-year warranty. The Inferno comes in Inferno and Darkness Inferno; the Tornazo in Purple and Shadow.

Luzz also mark all four as USAP certified. We could not find them on USA Pickleball's equipment list, so treat that marking as a manufacturer claim until it appears there, and check your event's own sanctioning body before you play. We would rather tell you that than repeat a spec sheet.

All four Luzz paddles are available to pre-order. We do not have a confirmed landing date from the supplier, so we are not going to publish one.

You don't have to buy Luzz to buy any of these ideas. Friday build their range around foam cores and have done for years — we covered the Aura and Aura Pro separately. The Enhance MPP Turbo 16mm Hybrid runs the same microporous polymer core family as the Inferno, at $180.

What should you actually buy

First proper paddle? Don't chase Gen 4. Learn what you like before you pay to optimise it. The Six Zero Quartz at $99, or anything in the beginner paddles collection, will teach you more about your own preferences than a $369 foam core will. A foam core does not fix a third-shot drop.

Intermediate, want the modern feel without pro-tier money? You want 16mm with foam somewhere in it. The Luzz Cannon at $175 and the Enhance MPP Turbo at $180 both get you there — both are pre-order. The Friday Aura at $215 is in stock and arrives at the same place from a different direction. Start with the intermediate paddles collection.

Want the plushest, longest dwell available, and you know why? Full foam — the Pro 4 Inferno or Tornazo at $369. Eyes open: newest construction, least long-term durability data, and foam longevity is still the open question.

Want a paddle in your hand this week? Buy something in stock. The RPM Q2 16mm Elongated at $357.50 sits in the professional range; the Friday Aura at $215 in the middle; the Quartz at $99 to start. Everything Luzz is pre-order. Our Six Zero dealer guide covers that range in depth.

Notice what the price ladder does not do: track the technology ladder. The Cannon is $175 and thermoformed with a foam layer. The Glider is $189 and honeycomb. Construction is not a proxy for quality, and the generation number is not a proxy for anything.

Pickld stocks every brand named here — Luzz, Six Zero, Friday, Enhance and RPM. The guidance above is based on published construction specs and how these paddles play, not on which one earns us the most.

The bottom line

The jargon isn't a conspiracy. Thermoforming really did make paddles more forgiving. Foam really does hold the ball longer. Raw carbon really does grab it.

What isn't real is the ladder — the implication that a bigger number means a better paddle for you specifically. There's no governing body behind "Gen 4". There's swing weight, twist weight, core thickness, and how a paddle feels in your hand at 8pm on a Tuesday.

Frequently asked questions

What is a Gen 4 pickleball paddle?

A Gen 4 pickleball paddle replaces the traditional polypropylene honeycomb core with engineered foam — microporous polymer (MPP), or a PEBA-based super-foam. The foam compresses and rebounds on impact, giving a plusher feel, longer dwell time and a more evenly spread sweet spot. The caveat matters: "Gen 4" is a manufacturer marketing label, not an official classification. No governing body defines it, and brands apply it inconsistently.

Is a foam core better than a polypropylene honeycomb core?

Not automatically — they're different tools. Foam holds the ball on the face marginally longer, which helps spin and touch, and tends to widen the sweet spot. Honeycomb is crisper, more predictable, and has years of real-world durability behind it. Foam is the newer technology, which makes it more interesting, not automatically better.

Do foam-core pickleball paddles go dead over time?

They can, and it's the honest reservation about the Gen 4 category. Foam takes a compression cycle on every hit, and early foam paddles gained a reputation for softening and losing rebound over months of regular play. The paddle doesn't visibly fail; it just gets dull. Newer crush-resistant formulations respond directly to this. Warranty length is a useful proxy for manufacturer confidence — both Luzz Pro 4 paddles carry a one-year warranty.

Does a carbon fibre face actually add spin?

Partly. Spin is a product of surface friction and dwell time. A carbon fibre face — particularly raw and unpainted, or treated with a grit coating like 984-Aero™ or a 3D grooved weave — provides the friction. The core provides the dwell. You need both. And every legal paddle surface wears: a well-used gritty face won't generate the spin it did when new, whatever it cost.

Should I buy a 14mm or 16mm pickleball paddle?

A 16mm pickleball paddle has a thicker core, meaning more dwell, softer feel and more control. It's the default for all-court and control-oriented players, and what most current premium paddles use. A 14mm core is stiffer and pops the ball off the face faster, favouring power, but with a smaller margin for error on off-centre hits. Undecided? 16mm is the safer buy.
