From The Manufacturer

The most unique feature of the SISU Aero is its super-slim, ultralight design. At a lean 1.6 mm, the Aero is 50% thinner than a standard mouthguard. Combined with its quick, custom and remoldable fit, it’s easy to forget there’s something awesome and plastic inside the mouth. Sisu Aero is available in 3 sizes; Small, Medium, and Large. SISU guards are made from a material that absorbs and diffuses impact throughout the entire mouthguard, meaning that much less impact force is transferred to the teeth. Using one-of-a-kind Diffusix Technology, the impact force is distributed over larger areas, which means less risk of dental injury during competition. Conventional mouthguards are made from a material that’s too soft to fully protect teeth from harm.

What reviewers didn't like

Probably won't fit younger children (recommended for 11 and up). On the pricey side. Some users said they had a difficult getting to mold properly to their mouth
- Heavy
Not recommended for extremely high impact sports. Material can get bitten into to cause holes to form. Slightly pricier than other boil and bite mouth guard. Material can fold onto itself during the molding process if you aren't careful!
