The size 1 is a mini ball. Thus you’ll need to check with your local league to know the size requirements before making a purchase. The MLS Glider has a unique TPU exterior material that resists abrasion and a butyl bladder that will keep it in shape and inflated for a long time. It is machine stitched and also has nylon wound carcass inside for durability and long-lasting performance.
Latex bladders are one of the best materials when it comes to ball construction. However, with latex bladders, air won’t last as long as butyl bladders and will need more attention for proper inflation. Butyl-blend bladders hold in the air much better, but they are harder and less receptive in play. Mid-priced balls will usually have a mix of butyl and rubber. https://www.youtube.com/watch?v=c1SVcjYY6TE
