Mountainside JBO Customized DeMarini Backpack

We will once again be putting in a bulk order as a league for our fully customized DeMarini backpacks.   

So that the backpacks will be ready by the start of the season, we will stop taking orders on Sunday, March 7th.   We will hopefully have a 1 week turnaround time to have the backpacks back, but we will know more shortly.

While these high quality, fully embroidered backpacks were  a big hit last year, with most of the players ordering them.  But, they are not mandatory.

MavUp Drinkware Update

The first order for the MavUp drinkware, including player's only bottles, has been sent in and we should have them onhand shortly.

We plan to take orders for a 2nd round of player bottle and Mountainside JBO drinkware orders upcoming, sometime in May. 

We have also ordered a small inventory of our top selling products, that we will have on hand to sell to families who might have missed out on the program.  

Sales sheets can be found below if you click on the link.  Just print out, notate what information to include on any custom products, and email back to us at ; you can then remit payment via Venmo to @mountainside-jbo and we'll add you to our order list; look for the horse head logo on our Venmo account and please list the items you're purchasing.
