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

Great ball for price

Best ball I have ever owned anywhere near this price point. Decathlon says it’s entry level. Super good quality. Definitely could be used indoors if you’re on a budget. This is my outdoor ball. I can speak to durability….but out of the box I’m very happy.

Daughter loved iy

hoping to be good

I am going to get this basketball and i hope its nice and durable as im a average teen playing basketball in my school team. For the price I am happy and i also really love the design of the ball. In the future, i will upgrade to the more expensive balls as they last longer and have a better 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

icon-circle-checkmark verified purchase
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

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 groupsSize 6: Boys ages 11 and 12 / Under 13 age groupSize 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.
