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.
Size 5 is the official size for professional matches. Therefore, this ball is only available in this size. Do not use this soccer ball on concreted areas. Its unique rubber uses Puma Airlock Valve Technology (PAL) in order to facilitate proper airlock technology. This ball features Perimeter Balance Technology (PBT) which enables it to maintain impressive flight characteristics. https://www.youtube.com/watch?v=j2Xn84L3Kcs
