Leatt Fusion 2.0 for Juniors Gives Parents Peace of Mind

Downhill mountain biking and BMX is a blast, but all parents have that constant feeling of anxiety when it comes to their beloved child. Leatt can help to alleviate some of that worry with their innovative Fusion 2.0 for juniors.

The Fusion 2.0 takes the complexity out of trying to mix and match compatible protective gear, which can be not only time-consuming and frustrating but also pricey. The Leatt Fusion 2.0 offers a Leatt neck brace coupled with chest, rib, back and shoulder protection all in one easy piece of equipment. Your child's spine, chest and vital organs are protected by Leatt's high-tech 3DF foam. We tend to worry about our kids, but we love how the Fusion 2.0 gives some peace of mind to us worrisome parents. It is the best way to protect your child at a cost effective price. 

The neck brace on the Leatt Fusion 2.0 for juniors uses alternative load path technology to protect the neck and spine. When impact occurs, the full face helmet and neck brace divert the force from the sensitive neck area to other muscle groups such as the chest, shoulders, and back. This technology helps limit the chances of injury from hypertension, hyperflexion and other serious neck injuries. 

The Leatt Fusion 2.0 for juniors features has 3DF padding throughout its design. 3DF pads are soft and pliable in your hands. You can squeeze the foam and bend it any way you please. However, the foam reacts differently to sharp, forceful impacts. Upon impact the 3DF padding stiffens and absorbs the impact. It returns to its original soft, pliable state immediately after impact, and can take multiple hits. Lightweight and comfortable, 3DF foam feels like a soft shell, but acts like a hard shell. 

Adjustability is easy on the Leatt Fusion 2.0 for juniors. A velcro designed adjustability system allows for the maximum amount of fit customization and will help to make fit quick for any growing child. The neck brace also has sizing spacers so the brace can grow with your child and be used for a long time. 

The Leatt Fusion 2.0 is what every parent should invest in if their child loves downhill mountain biking or BMX, but they don't love to worry. 

About Leatt

Sometimes it takes tragedy to make change. Such was the case in South Africa in 2001 when Dr. Chris Leatt, a medical doctor and motorcycle rider, went to a racetrack with his son who himself had just begun to ride. There, Dr. Leatt witnessed the death of another rider, Alan Selby, from suspected neck injuries. Dr. Leatt was so shaken by the incident that he made it his mission to develop a device that would go a substantial way toward preventing this type of fatal injury in the future. After three years of research, development, and testing, Dr. Leatt introduced his first Leatt-Brace. However, it would be another two years before the Leatt-Brace would make it to market on a large scale. Today, Leatt-Brace is a worldwide leader in neck protection for extreme sports. Designers and engineers in the Leatt laboratory in South Africa have expanded their reach to high-technology protective armor that meet varying needs of downhill mountain bikers, bmx bikers, and skiers and snowboarders.
