2027 Easton Dub Darkside -10 Travel Ball 1.15 BPF Baseball Bat EUT7DBDS10

The 2027 Easton Dub Darkside -10 Travel Ball 1.15 BPF Baseball Bat - EUT7DBDS10 combines Easton's second-generation double-barrel composite construction with a balanced -10 swing profile built for players who want fast barrel speed, smooth feedback, and a large 2 3/4-inch barrel.

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 two layers work together to create a flexible hitting surface with the distinctive feel and sound that separates the Dub from a traditional single-wall composite design.

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, controlled feel through repeated 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 that allows the outer hitting surface to flex while the inner structure supports the barrel underneath.

Compared with a conventional single-wall composite construction, this design gives the Dub a distinctly flexible barrel feel and helps create a large usable hitting area from taper to end cap.

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. That means the appearance of each bat can develop differently depending on how and where the barrel is used.

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 maintaining a connected feel between both sections of the bat. That can be especially noticeable on contact away from the center of the barrel.

Opti-Flex Handle

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

This allows Easton to tune handle characteristics to complement the barrel and swing profile of each specific model.

For the -10 Dub Darkside, the goal is to maintain a controlled, responsive feel while allowing developing hitters to generate the barrel speed expected from a lighter drop weight.

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 hitting zone.

Balanced -10 Swing Profile

The -10 length-to-weight ratio gives the Dub Darkside a lightweight, balanced swing profile designed to promote bat speed and barrel control.

Rather than concentrating excessive mass toward the end of the barrel, the balanced weight distribution helps developing hitters accelerate the bat while maintaining control through contact.

That makes the -10 a useful option for players who want the barrel size and composite construction of the Dub without moving into the heavier feel of a -8 or -5.

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, the larger diameter gives hitters a substantial hitting surface while the balanced -10 configuration keeps the overall swing manageable.

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 -10 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.
