## Marucci CAT X Composite Bat


The Marucci CAT X Composite is another innovative model within the Marucci CAT series, expanding the brand's offerings to players who prefer composite bats over alloy. Composite bats, known for their lighter weight and larger sweet spot, provide a different feel and performance compared to their alloy counterparts. Marucci's offerings, like the CAT X Composite bat, stand as a testament to the brand's unwavering pursuit of excellence in every swing.

**Perfect bat for:** Youth players looking for a bat that offers superior lightweight performance with a large sweet spot.


### Key features include:



* **Maximum Composite Performance:** Utilizes a precision-balanced, maximum composite barrel that delivers a larger sweet spot and higher overall performance.
* **MDX, Multi-Directional Composite:** Provides fine-tuned performance and weight distribution, ensuring a balanced feel for greater control and faster swing speeds.
* **Ring-Free Barrel Construction:** Allows for more barrel flex and increased performance with no "dead" spots, offering a consistent and powerful hitting surface.
* **Sting-Free Comfort Knob:** Features an ergonomic design that reduces vibration and improves comfort, allowing players to swing with confidence.
* **Two-Piece Composite Construction:** Delivers a smooth, responsive feel throughout the swing, enhancing control and reducing feedback on mishits.
* **Micro-Perforated Cushy Grip:** Ensures optimal grip and comfort, allowing for tighter control and minimizing hand fatigue during extended play.

### What people are saying (edited for clarity and brevity)

**PROS**



* Bought for son transitioning to BBCOR. Light and balanced. Good pop and sound. Great balanced BBCOR bat!
* Like cheating, it’s awesome! Whole barrel is super hot. 33” sweet spot
* Bat has huge sweet spot. Lots of pop!

**CONS**



* My son's bat grip is separating already. The bat lacks the usual sound of CatX or Cat8 bats. We paid extra for the grip, but it's coming apart fast. 
* The price doesn't deserve more than 4 stars, but we appreciate the fast shipping and the name engraving.
* Bought this bat for my 14 year old, felt good during batting practice, but the second he hit the ball in game it broke in half! 500 dollars down the drain.


### **Certification**: USSSA, BBCOR


### Expert Notes ([Tony](https://sidelineswap.com/locker/batexperts))

The CAT X Composite is very, very easy to swing. Not quite as popular as the CF in terms of performance. There are newer Marucci  bats out there that are stronger, hotter-performing bats. But it's still a top top-tier bat. It's right up there with the CAT9 composite, but it doesn't get the notoriety because you've got some newer bats on the market with cooler paint jobs.
