2027 DeMarini Island Kings Slowpitch Bat Review
DeMarini's first one-piece 240-style USSSA slowpitch bat — a 13" end-loaded composite built stiff for maximum distance. A power hitter's bat, not a control bat. First-pass rating.
The Score
How we score ↗How big and forgiving the barrel is — based on barrel length, construction (one- vs two-piece, alloy vs composite), and how it plays on balls hit off the center. A primary driver of the overall score.
Raw exit velocity and distance. We use measured numbers from freely available independent testing when they exist; otherwise construction and consensus, judged against the certification’s performance ceiling. A primary driver of the overall score.
Comfort and feedback on contact — vibration dampening from the knob/connection, the sting of a stiff one-piece vs a smooth two-piece, and the sound off the barrel. A primary driver of the overall score.
How well it holds up and how the company stands behind it — documented cracking/denting reports, cold-weather behavior, and the brand’s real warranty record. Good to know, but weighted lightly in the score.
Our take on price-for-performance — the overall package weighed against its cost and what comparable bats run. Shown for context; it is NOT factored into the overall score (price changes too often and is personal).
Why this score: First-pass rating: scored as a stiff, end-loaded one-piece distance bat — big power, heavier swing, harsher feel. Per our brand policy we weight durability and value with DeMarini's record in mind. We'll confirm with testing.
Our Review
The Island Kings is the power piece of DeMarini's 2027 themed USSSA slowpitch run — the brand's first one-piece 240-style build, with a 13" high-compression composite barrel and an end-loaded swing weight that shifts mass toward the cap. One-piece construction keeps the whole bat stiff, so nothing bleeds off at contact; the trade is more feedback to the hands and a swing that asks for genuine bat speed. For big swings chasing max distance it's the pick of the trio; for everyone else the balanced El Mero Mero is the easier bat to hit with. This is a preliminary first-pass rating from the bat's build, platform and class; we'll firm it up once there's real game feedback. As with any DeMarini bat, weigh durability and warranty before buying — the brand's record on both trails the field.
