Barrel Max bat Warmer Sleeve Silver/Black

I play indoor softball in the winter and it is always cold in the building where we play. A composite bat likes the warmth it kept the bat warm through most of the game with the hand warmers.

My 9U son uses this in early spring morning tournament games. He’s hit some bombs when other teammates bats have been dead. It takes 4 warmers and it helps to start the hand warmers an hour or two before you play. I truly believe warm aluminum alloy gives more and creates more pop.The only negative is that it’s pretty snug in a 2 3/4 inch barrel, so it can be difficult for a 9yr old to get the back bat in after they are done using.

This thing actually works pretty well. I find we have a better result if we give the packets a lot of time to warm up and when we keep the sleeve zipped up.She starts her high school season soon so we'll see if it is ever deemed illegal. It's kind of in a gray area.

My son uses it for cold games. Seem to help. Also keeps his bat from getting damaged

Works well with the hand warmers. Doesn't take up a bunch of extra space in her bag. We've played in as low as 36 degrees and have not had any issues with her bats.

I used this product once and the zipper broke and now it is almost impossible to use. I would like a replacement or a refund

One of the inside sleeves were ripped.

This is a must buy to protect your expensive two piece bats! Avoid a broken bat due to the cold.
