What a great product this is!! It would have been out of reach for our kids if it were not for SISU’s support. These are official mouth guards for US Lacrosse. Find them by clicking below.

Sisu is a Finnish word which means among other things “Deciding on a course of action and then sticking to that decision…”. SISU not only produces a great product but supports the lacrosse community with outreach where is most needed. Thanks for the shoutout at the SISU Blog here. Your sponsorship and support is very appreciated.
