If you've ever swung an Easton Ghost or played against a hitter swinging one, you know the sound. It's not a tink. It's not a thud. It's the Ghost sound — and the technology responsible for it has a name: Double Barrel.
This post walks through what Double Barrel actually is, why it produces the feel and sound that made the Ghost line legendary, and where it shows up across Easton's current fastpitch lineup.
What Double Barrel actually is
Easton's official explanation, in their own words: Double Barrel features "an inner barrel nested within the outer barrel, creating an extraordinarily large sweet spot and the explosive barrel response Ghost hitters have recognized for years."
That's the construction in one sentence. There are two distinct barrels — one inside the other — instead of a single-wall or simple multi-wall composite layup. The two barrels work as a tuned system: the outer barrel is the structural shell and the inner barrel is engineered for compression and rebound at contact.
The result is the Ghost's signature feel:
- Soft barrel compression at contact, which is what gives Ghost hitters that "trampoline" sensation when they square the ball
- A large, forgiving sweet spot — because the two-barrel system spreads the responsive zone over a wider area of the barrel
- The Ghost sound — that unmistakable mid-pitched crack that comes from the inner barrel deforming inside the outer one and rebounding
Why hitters notice the sound
The Ghost's sound isn't a marketing gimmick — it's a direct byproduct of the construction. A single-wall composite barrel rings one way. A two-barrel system, where the inner barrel is doing most of the compression work, rings a different way. The frequency and decay of the sound at contact is part of the feedback loop hitters use to know they squared it up.
Players who have grown up on the Ghost line learn that sound and trust it. It's why hitters who try a Ghost rarely go back to a single-wall bat in fastpitch.
Double Barrel across the 2027 lineup
Easton uses the Double Barrel name across the entire Ghost family, but the exact implementation varies by model:
- 2027 Ghost OG (EFP7GHOG) — Patented Double Barrel, no version suffix. The original implementation, the classic feel.
- 2026 Ghost Advanced (EFP6GHAD) — Patented Double Barrel paired with the Sonic Comp Max composite for the upgraded two-piece build.
- 2026 Ghost Unlimited (EFP6GHUL) — Double Barrel EXT — an extended version that creates what Easton calls "the longest barrel in Ghost history" with a roughly 1" longer barrel and an extended sweet spot. Used in the one-piece Unlimited.
The Ghost OG keeps the classic Double Barrel build because the OG's whole pitch is faithfulness to the original Ghost feel. Want the full breakdown? See our OG vs Advanced vs Unlimited comparison.
What Double Barrel pairs with on the Ghost OG
The Double Barrel construction is the headline feature, but it doesn't work in isolation. On the 2027 Ghost OG it's tuned to work with:
- Sonic Comp composite — the high-performing composite engineered for enhanced durability and consistent performance, with the low compression and sound that made the Ghost lineup legendary
- ConneXion two-piece construction — promotes firmer barrel flex for maximum energy transfer while minimizing vibration on contact (two-piece vs one-piece explained)
- Flow+Tack 1.8mm perforated grip — quality feel and control on every cut
- Balanced swing weight — across every drop (-8 through -11). See our drop guide to dial in your fit.
- 2 1/4" barrel diameter
The Double Barrel is what gives the Ghost its character. Everything else on the bat is tuned around it.
Is the Ghost the only bat with two barrels?
Other manufacturers have made multi-wall and dual-wall composite bats over the years. What's specific to Easton is the patented Double Barrel construction and the way it's tuned in the Ghost line — and the feel and sound that come out of it. That's why a Ghost feels and sounds like a Ghost and not like a generic two-wall composite.
If you're shopping a fastpitch bat and you see "double-walled" or "two-wall" in a non-Easton bat's description, that's a related but different design concept. Easton's Double Barrel — particularly in the Ghost lineup — is the specific implementation that produces the Ghost sound.
Bottom line
Double Barrel is the patented Easton construction at the core of every Ghost fastpitch bat. An inner barrel nested inside an outer barrel, working together to produce a large sweet spot, soft compression at contact, and the Ghost sound that's been recognized in dugouts for years.
