Why learn to play basketball with the tarmak r300 ball?

The Tarmak R300 basketball is perfect for beginners. Ball handling is enhanced thanks to the deep grooves and pebbled cover.Foam rubber (air is injected into rubber, which creates a softer consistency) for softer impacts.Its filament winding is made from 100% polyester, ensuring good-quality bounce.Very durable for indoor and outdoor use.

What ball size to choose?

The ball size depends on the player's age and gender.Size 1: From ages 2 and up Size 3 to size 5: Girls or boys ages 4 to 6 / under 7 age group (depending on levels and clubs)Size 5: Boys and girls ages 7 to 10 / Under 9 and under 11 age groupsSize 6: Boys ages 11 and 12 / Under 13 age group. Size 6: Girls - Women of all ages over 11 Size 7: Boys ages 13 and up, and men.

What ball should you use?

If you want a very durable ball, go for a rubber ball. If you're looking for a ball with a good ball feel, choose a leather or synthetic ball.

For a good bounce, how much should you inflate your basketball?

A basketball that is overinflated or underinflated will deliver a sub-par playing experience.The recommended pressure is clearly marked on the ball by the manufacturer. Ideally, you should use a pump with a pressure gauge for a more precise inflation.At Tarmak, we recommend a pressure of 0.62 bars.Enjoy your game!
