CAT9 Composite

## Marucci CAT9 Composite Baseball Bat

The Marucci CAT 9 Composite bat represents a significant advancement in Marucci's approach to building bats for players who prefer the feel and performance of fully composite construction. Unlike its alloy counterparts within the CAT series, the CAT 9 Composite provides a massive barrel and balanced swing. With a philosophy deeply rooted in the insights and needs of actual players, Marucci’s Cat 9 Composite bat showcases the brand’s proficiency at using cutting-edge materials to elevate the performance of players at any age.

**Perfect bat for:** Both contact and power hitters who don’t mind a barrel-heavy bat.


### Key features include:



* **Multi-Directional Composite Material:** Creates an ultra-responsive barrel that offers a significant performance advantage across the entire hitting surface.
* **Maximum Barrel Length:** Provides a larger sweet spot and enhances the potential for off-center hits to still travel far and fast.
* **SDX LT Connection:** Reduces vibration on contact, delivering a more comfortable hitting experience without sacrificing power on swing-through.
* **Ring-Free Barrel Construction:** Eliminates dead spots for a more consistent performance and allows players to take full advantage of the bat's technical design.
* **Micro-Perforated Soft-Touch Grip:** Ensures comfortable, secure handling even in rigorous play conditions, reducing hand fatigue and enhancing control.
* **Balanced Swing Weight:** Optimizes bat speed and control, offering a perfect blend for hitters who value precision as much as power.


### Top competitors comparison: [DeMarini CF Zen](https://sidelineswap.com/shop/baseball/bats/demarini/cf-zen-2020/l8432) and the [Easton ADV 360](https://sidelineswap.com/shop/baseball/bats/easton/adv-360/l59709)

The Marucci Cat 9 Composite shines with its use of multi-directional composite materials, enabling a level of responsiveness and barrel performance that's hard to match. While the DeMarini CF Zen is praised for its consistently strong performance across the barrel and the Easton ADV 360 offers revolutionary 360-degree barrel tuning, the Cat 9 Composite distinguishes itself with a superior balance between speed, power, and comfort, courtesy of its meticulous engineering and vibration-dampening connection technology. This makes the Cat 9 Composite a top choice for youth players aiming to elevate their game with a bat that delivers fluidity and force in equal measure.

* Huge sweet spot and very durable. Has a great feel and sound to it. 

**CONS**



* A few hits scuff paint off bat.
* When it doesn’t get hit on the sweet spot it doesn’t go very far and stings.
* It's a lilttle pricey and i already broke it... but i am going to buy a new one


### **Certification**: USSSA, USA, and BBCOR


### Expert Notes ([Tony from BatExperts](https://sidelineswap.com/batexperts))

The CAT9 Composite comes in two designs across two generations. The first, released in 2021, is gray, black, and red. And then it came out in red, white, blue, and gray. The first model was a more powerful, higher-performing bat. It has more exit velocity and is a hotter bat than the 2nd gen. Very durable, with very little breakage. Marucci's, across the board, have been good bats in terms of quality; they seem to last. Whether you're a power hitter or a small kid, the CAT9 Composite does very well.
