The ULTRACORE system is intended for very tall ballers who dig the most adherent section of the bag! You get the amazing CORE ballstretcher - it has outer ribs for a super long stretch: it stays higher on your bag with a more padded grip in the middle for fat bag compression.

You also get the rubbery AXIS power ring that grips the ribs - it has channel ribs on the inside of this shape with the outside ribs on the CORE stretcher. CORE ballstretcher is an amazing ballstretcher on its own - on your nuts, the smooth inner tunnel wraps your bag with medium firm pressure, but add an AXIS power ring on top of the toothed CORE and get the most MAX BAG SQUEEZING.

We sweat the big stuff when we design for your ball needs, we think more about new ways to stretch you harder - we do so much research on ball bags, seriously we look at your balls a lot), we see you stretchers stack our rings for insane bag compression - ULTRACORE has the features to maximize your stretch.

HOW TO WEAR: a little lube or spit, sweat shower is good, stretch the core and drop your bag and adjust it where you want it, the inner hourglass shape will hold where you put it. If you want maximum compression effect, slide the AXIS stretch ring over the CORE midrib for better grip...

Made from our extra-soft Plus+ SILICONE blend, it will keep the grip firm enough with a smooth, comfortable rubbery stretch, and the right grip for more play.
