"reject product"

This was not properly tested or did not pass quality inspection, it has a very very small hole that can not be seen by human eye... and when you play the ball the air inside the ball slowly subside and the next day the ball is almost fully inflated...

easy to play

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 groups Size 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!

What height basket should you choose?

The official height of a basketball basket is 10 ft. (rim height). If you want a basketball basket for your child, you need something that will grow with them. For younger kids there isn't an official height so you can choose whatever suits them best. Up to the age of 10, club baskets are set at 8'6". After the age of 10, both girls and boys play with 10' baskets.
