2027 Easton Dub Darkside -5 Travel Ball Baseball Bat EUT7DBDS5

The 2027 Easton Dub Darkside -5 Travel Ball 1.15 BPF Baseball Bat - EUT7DBDS5 combines Easton's second-generation double-barrel composite construction with a heavier -5 swing profile designed for stronger hitters who want more barrel mass without giving up a balanced overall feel.

At the center of the Dub Darkside is Easton's 2X Double Barrel Construction, which pairs a thinner, lower-compression outer barrel with a lightweight, durable inner barrel. The layered design allows the outer hitting surface to flex while the inner barrel supports the structure underneath, giving the Dub its distinctive feel, sound, and responsive composite barrel characteristics.

Easton backs the barrel with ConneXion Max, an elastomer connection system designed to reduce unwanted vibration between the barrel and handle. The Opti-Flex Handle, Gen2 In2uitiv Feel™ Soft Knob, and 1.8mm Flow+Tack™ Grip complete the handle side of the bat for a comfortable and controlled feel through aggressive swings.

2X Double Barrel Construction

The defining feature of the Dub Darkside is Easton's 2X Double Barrel Construction.

A thinner, lower-compression outer barrel is paired with a lightweight inner barrel to create a layered composite system. The outer barrel is designed to flex across the hitting surface while the inner barrel provides structural support underneath.

Compared with a conventional single-wall composite barrel, this construction gives the Dub a distinctly flexible feel and helps create a broad usable hitting area across the barrel.

Because this is a composite barrel, its characteristics can continue to change as the carbon fiber and resin structure is worked through repeated impacts. Players wanting to better understand that process can read our guide explaining what bat rolling is and how composite break-in works.

Darkside DUBLVZN Graphic Technology

The Darkside DUBLVZN graphic system gives this version of the Dub a visual design that changes as the bat is used.

An ultra-chrome outer graphic layer gradually reveals additional artwork underneath as repeated contact wears through portions of the surface. The result is a finish that develops its own appearance as the bat sees more swings.

ConneXion Max

Easton's ConneXion Max uses an elastomer connector to join the barrel and handle.

The system is designed to reduce vibration reaching the hitter's hands while keeping both sections of the bat working together through contact.

For stronger hitters taking full-speed swings, that smoother feedback can be especially noticeable on contact away from the center of the barrel.

Opti-Flex Handle

The Opti-Flex Handle is engineered around the specific size and weight of the bat rather than using one identical handle design across the entire lineup.

This allows Easton to tune the handle characteristics to complement the heavier -5 barrel and overall swing profile.

The result is a handle designed to maintain control and feel while stronger hitters accelerate the additional barrel mass through the hitting zone.

Gen2 In2uitiv Feel™ Soft Knob

The Gen2 In2uitiv Feel™ Soft Knob uses an asymmetric contour designed to create a more natural fit against the hitter's bottom hand.

Its softer shape can improve comfort during repeated swings while helping the player maintain awareness of the barrel throughout the swing.

Balanced -5 Swing Profile

The -5 length-to-weight ratio gives the Dub Darkside significantly more overall mass than lighter -8 and -10 models.

That additional mass can provide more barrel presence through contact, but it also requires greater strength and bat speed to control. The -5 is therefore best suited for more physically developed hitters who can maintain their mechanics while swinging a heavier bat.

Despite the additional weight, the Dub Darkside is designed with a balanced swing profile, helping keep the barrel manageable through the zone rather than creating an excessively end-loaded feel.

2 3/4-Inch Barrel

The 2 3/4-inch barrel provides the large barrel profile commonly found on Travel Ball 1.15 BPF bats.

Combined with the double-barrel composite construction and heavier -5 configuration, the larger diameter gives stronger hitters a substantial hitting surface with additional mass behind the barrel.

Flow+Tack™ Grip

The bat is finished with a 1.8mm Flow+Tack™ perforated grip designed to provide a secure connection to the handle without excessive thickness.

The perforated surface helps maintain grip control while preserving enough feedback through the hands to stay connected to the barrel.

Composite Break-In

The Easton Dub Darkside -5 uses a double-barrel composite construction, and composite barrels can change as repeated impacts gradually work the carbon fiber and resin structure.

Players who prefer to break the barrel in entirely through hitting can do so naturally. We explain the differences between natural break-in and mechanical break-in in our guide to bat rolling vs. natural break-in.

For customers who do not want to spend an extended period breaking in a new composite barrel, Big Dawg Bats also offers our Precision Bat Rolling Service as an optional service for qualifying composite bats.

Customers considering internal barrel modification can also review our Composite Bat Shaving Service and the durability tradeoffs associated with that process.

Before & After Compression Verification

Every serviced bat includes before-and-after Compression VERIFICATION Video so customers can see the actual compression readings from their bat rather than relying only on reported numbers.

The numbers matter — but being able to see the test provides an additional level of verification.
