Jimalax Prime Semi-soft mesh uses a new tighter weave to deliver a thinner, stronger and tighter weave that is waterproof and wont bag out like the rest. Jimalax was one of the originals in the elite lacrosse mesh production game. Don't let the MADE IN USA price fool you - this Jimalax Prime is premium high school and collegiate level mesh that will be making a big splash in the market this year.
