COMBAT B4 Portent XL: B4SL210 Senior League review by Pat E
Pros: Purchased this bat for my 9 year old grandson based on reviews and it has not disappointed us. Great pop out of the box. His hitting seems to have improved instantly. First at bat hard line drive past short stop. Second at bat hit by pitcher. Third at bat best hit ever. Had wind not been blowing in hard towards home plate it would have been over fence. Sadly, the rain started and cancelled the tournament. His confidence has greatly improved using this bat. Very pleased. Can't wait for next game. Cons:None yet

Ask A Question

My son is 8. He weighs 76 lbs and is 55" tall. What bat would you recommend?

I would highly recommend the COMBAT B4 Portent XL (B4SL210). Based on your son's height and weight, I would recommend a 28" bat.

Justin R. Expert ·Apr 13, 2014


My son is 7 years old (will turn 8 Sept 1st). He is big for his age (56" 115-120lbs) and is moving up to play with pitching machine/kid pitch, Mustang league. What do you recommend? The chart says 29" but I wonder if 28" is better for now.

Using our Bat Coach, I determined that a 29" bat would be the size I suggest for your son in the COMBAT B4 Portent XL (B4SL210).

Some leagues don't allow composite bats. Can my son use this bat in 8U under Nations Baseball?

According to the Nations Baseball website there are no restrictions in that age group. Therefore, the COMBAT B4 Portent XL (B4SL21) would be legal. Here is a link to the website:

Product Description

New for 2013! COMBAT's new B4 Portent XL is not just any big barrel bat. With it's enlarged 2 3/4 inch barrel, the B4 Portent XL has a HUGE hitting surface and COMBAT's new FULL BARREL SWEETSPOT! Yes, you read that right. There is no such thing as a mishit with this bat, and that's just the tip of the iceberg. It all starts with COMBAT's Localized Stiffening Technology that allows their engineers to lower barrel wall stiffness on both sides of the normal sweet spot, resulting in an enlarged sweet spot area where absolute maximum performance can be achieved! The 100% composite, one-piece B4 Portent XL utilizes COMBAT's Blended Fiber Technology that blends several different fibers in varying proportions at carefully controlled angles to create a composite material that results in both resilient durability and increased trampoline effect. Separation Barrier Technology also allows this bat to be HOT out of the wrapper! SmartFlex and SmartPly technologies work together to make this the smartest bat ever constructed. The result is a continuous store-and-release monster that will allow players to think beyond the warning track, beyond the wall, and beyond the park. COMBAT: For Players, By Players. The B4 Portent XL features the USSSA 1.15 BPF Stamp. It is backed by a Full Twelve (12) Month Manufacturer's Warranty. Free Shipping!

All I can say is shipping was quick!!!. My son had a game last night and I didn't even consider the bat being here in time for it..Well, we got the bat in 2 days and he was able to use it last night. This bat is great and you guys were awesome in getting it shipped. I recommended y'all at our game last night.. and I already know of one order I got for you on the same bat I ordered. That bat is due in today and that boy has a game tonight... so I'm sure he'll be happy as well... Sincerely,
