YoYoFactory - Boost

3A US Champion, Alex Hattori personally lent a hand in designing his new signature bimetal model.

Well known and loved 3A champion Alex Hattori personally took part in the design of the Boost, the latest high quality bimetal throw from our friends at YoYoFactory. With a light body weighing in at 64 grams, the balance of width and diameter lend a powerful boost to the Boost, bringing both the spin and the stability to a very high level, very important aspects for a good 3A yo-yo!

The shape looks like it's a straightforward step-straight, but there's actually an inverse round profile to it; the spin refuses to die, giving you remarkable sleep times to play with!

The tall profile makes Boost a full sized yo-yo by the numbers, but the balanced design and sense of power makes it feel like you've picked up an oversized throw. Get boosted today!

Official Description
Alex Hattori will compete this year to become the most successful player of ALL TIME at the USA NATIONAL CONTEST.

To achieve this goal we gave him a blank canvas to design his first YoYoFactory signature YoYo. Alex has a history of design including Battle Robots and has even created a plastic YoYo during his studies at MIT so we knew his was capable of achieving something great.

He didn't just make it great. BOOST is AMAZING.

At 64gm it has the power of a much heavier yoyo, which is something magical that many designers aspire to but few achieve. This is found in the achievement of a near perfect balance between speed and stability.

Not since the Genesis have YoYoFactory released a yoyo that will appeal to so many players across so many styles.
