SISU Mouthguard will become the official mouthguard of US Lacrosse and Team USA, offering the world’s top lacrosse athletes custom-fit mouthguards powered by SISU’s unique Diffusix™ Technology.
“With safety at the forefront of concern across the sport of lacrosse, we’re excited to begin this partnership with SISU Guard,” said Ms. Susie Chase, vice president of philanthropy and partnerships for US Lacrosse. “The SISU Mouthguard is a best-in-class product for our national team athletes, and lacrosse players of all ages, and we appreciate the commitment to US Lacrosse in helping us grow the sport.”
SISU Mouthguards are 1.6mm thin protective dental shields, made from a non-compressible, perforated, remouldable thermal polymer. Powered by Diffusix™ technology, SISU Mouthguards deflect impact forces and absorb shock. Scientifically-engineered perforations create a custom fit and allow for a natural flow of air and saliva, to help improve communication on the field and increase athletic endurance, due to better breathability.
“From the moment we attended our first tournament, it became clear that SISU Guards were not only welcome, but absolutely essential in lacrosse,” said Ms. Sassa Akervall, CEO and majority owner of Akervall Technologies, the makers of the SISU Mouthguard. “With improved communication and better endurance, our guards have become the go-to brand for lacrosse athletes nationwide. The experience and network of the US Lacrosse team and their commitment to growing the sport is what makes them the ideal partner. We’re excited to become their official mouthguard and, through this partnership, bring higher safety standards and better communication to the lacrosse community.”
As a part of the partnership SISU will also be contributing to US Lacrosse grant programmes including the First Stick programme and Diversity & Inclusion initiatives.
