##  DeMarini CF Baseball Bat


The CF series is DeMarini’s flagship line of composite bats, known for their innovative technology and exceptional performance for a wide range of players. The CF series combines comfortable contact, explosive power, and unmatched swing speed. Featuring Paraflex Plus Composite construction, the CF series has a large, light sweet spot, and its 3Fusion Connection dramatically reduces vibration and enhances weight distribution. 

**Perfect bat for**: Young players seeking a two-piece composite bat with maximum barrel control and pop.


### Key features include: 




* **Paraflex Plus Composite Barrel:** Engineered for consistent and responsive performance across a wide hitting area, enhancing pop and feel.
* **3Fusion Connection:** Reduces vibration and redirects energy back into the barrel, improving performance and comfort.
* **ReAction End Cap:** Increases barrel performance without compromising swing speed, optimizing the overall balance of the bat.
* **Two-Piece Construction:** Delivers a nice flex at contact, creating a whip effect that drives the ball with more force.



### Top competitors comparison: [Louisville Slugger Meta](https://sidelineswap.com/shop/baseball/bats/louisville-slugger/meta/l59403) and the [Easton Ghost X Evolution](https://sidelineswap.com/shop/baseball/bats/easton/ghost-x-evolution/bat-material-composite/l228675)

The DeMarini CF stands out with its exceptional use of Paraflex Plus Composite and 3Fusion Connection technology, which provides a perfect blend of feel, flex, and performance. While the Meta is celebrated for its EKO Composite Barrel and balanced swing weight, and the Ghost X Evolution is recognized for its Dynamic Feel System, the CF shines with its ability to deliver a large sweet spot, reduce hand sting, and maintain a consistently high level of performance, positioning it as a top choice for players who prioritize comfort and power.

### What people are saying (edited for clarity and brevity) 

**PROS**



* A kid in a slump hit his first-ever home run with this bat. It arrived just in time for a playoff game and worked great for my average-sized 11-year-old son - not too heavy.
* After breaking in this bat properly, it really performs well! My son uses it for our USSSA 8U Travel team and you can easily tell when it's hit on the sweet spot. The bat is also forgiving on mis-hits, often resulting in faster grounders than usual (for this age group) and very high pop.
* This bat has more pop than most USA bats, similar to BBCOR/USSA. We broke it in with tee hits, and my son hit missiles and balls over the fence on the first day. Expensive, but worth it for avid players.

**CONS**



* Great indoor results with the new non-Easton bat during coach pitch pre-season. Disappointing mid-season pop-up infield hits. I've always used Easton before, won't try other brands again.
* Great pop, but poor performance when missing sweet spot. Treated with care, but still cracked in Apr. Son upset I didn't allow use in cold weather, with heavy balls or pitching machines. It was mostly used as game bat last year, did not last into 2nd season.
* My son's bat barrel cracked after hitting his first HR, leaving him without a bat during All Stars and elimination series.


### **Certification**: BBCOR, USA, USSSA


### Expert Notes (Parker)

The DeMarini CF is a classic model that goes back to 2015 and offers one of the hottest models (2017) but is limited in use as its performance surpasses bat standards. Overall, the CF reflects a classic design which has been the same since 2015. A two-piece composite that offers a large barrel and sweet spot with a lightweight handle that creates a whip-like feel to it with the flexible connection between the handle and barrel. 


Pop: ⭐⭐⭐⭐

Durability: ⭐⭐⭐

Vibration: ⭐⭐⭐⭐
