2021 DeMarini CF Fastpitch Bat Review
The 2021 DeMarini CF refines the Paraflex Plus two-piece formula with a vibration-dampening 3Fusion connection and ReAction end cap - a popular travel-ball bat whose appeal is undercut by DeMarini's durability reputation.

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: Excellent feel and pop, but DeMarini's durability history at a $380 price point holds down its durability and value marks and keeps it off our recommended list.
Our Review
The 2021 CF (WTDXCFP21) is DeMarini's premium two-piece fastpitch composite, again pairing a Paraflex Plus barrel with the 3Fusion connection - tuned this year for vibration damping and energy transfer - and a lightweight ReAction end cap for a balanced, quick swing. Elite travel and college hitters have long gravitated to the CF for its blend of feel and pop, and this version delivers a large sweet spot and a smooth, dampened sensation on contact. It is broadly legal across ASA/USA, USSSA, NSA, ISA and ISF. Our reservation is the same one that follows every DeMarini composite: durability. The brand carries a persistent reputation for bats that crack or lose performance early, and at a $380 MSRP that risk matters. The CF is a good-swinging bat, but on a category where we weigh how well a maker stands behind its product, it lands behind the field.
Also worth a look: Easton Ghost Unlimited — our top fastpitch pick - benchmark feel and pop with far stronger durability and warranty support.
Insider Note
On a visit to DeMarini's factory in Oregon, I saw 4-5 pallets of broken bats waiting on warranty returns - and was told that's a normal day. Durability has always been the knock on DeMarini, and it's a big reason we steer hitters to brands that stand behind their product.
