This ball is excellent for all surfaces indoor and outdoor. The seams are deep enough and allow a good grip.

Pay a bit more for a better ball

Good entry level Basketball but if you can pay a bit more as slightly lighter and better bounce

Better than its price suggests

I bought this for my son to take on holiday. It be same apparent that he preferred this over his other ball that was over 3 times as much

My 10 year old prefers this

Think it’s better for him rather than the smaller sizes to get used to a normal sized basketball. He can dribble fine and just needed to get used tot he weight for shooting. Too bad most courts are now closed! We will just practice passing for exercise I guess

Good grip. Bad bounce

Not recommended for full game. Ok for shooting

Synthetic Basketball

People will complain about the grip if compared with a rubber basketball but it offers enough grip to maneuver and perform the task. Really recommend for cement court as its life is better than other ball (except hard-surface version and some environmental conditions). But if you wanna change ball every month then go with rubberized basketball.

destroyed after a single match

i was impressed by the touch and feel of the ball when i saw it in the store but after using it for a while i am a bit disappointed since bounce is bad ,the ball loses its air in 3 days max and after a single match the outer skin god totally eroded and then the ball lost its grip and touch feel

Why learn to play basketball with the tarmak bt100 size 7 ball?

The Tarmak BT100 size 5 basketball is perfect for learning to play. Ball handling is enhanced thanks to the deep channels and pebbled cover. Its outer cover is made from foam plastic to give it a more cushioned feel that is softer on contact. Its filament winding is made from 100% polyester, ensuring good-quality bounce. It is very durable and can be used both indoors and outdoors.

What ball size to choose?

The ball size depends on the player's age and sex. Size 1: From ages 2 and up Size 3 to size 5: Girls or boys ages 4 to 6 / Baby basket 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 - Men of all ages over 13

What ball should you use?

If you want a very durable ball, go for a rubber ball. If you want a ball with a good feel, leather or synthetic are what you need.

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

A basketball that is overinflated or underinflated doesn't give you the best match experience. The recommended pressure is clearly marked on the ball by the manufacturer. Ideally, you should use a pump with a pressure gauge so that you can be more precise. At Tarmak, we recommend a pressure of 0.62 bars. Enjoy your match!

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.
