Review:
The Under Armour Armour Fit is a decent mouthguard with very nice features. I would say this is a very average mouthguard in regards to fit and comfort.
If I'm not mistaken, this mouthguard is being phased out as Under Armour is now having all of their mouthguards manufactured by Shock Doctor.
To fit this mouthguard, not only can you boil-n-bite the mouthguard but you can also microwave it to achieve the final fit. I believe this was the first mouthguard to have the microwavable technology to fit a mouthguard.
One of the biggest benefits of this material is that it is chew resistant and also hydrophobic (it won't absorb water). This is important because believe it or not, mouthguards that have been chewed on can harbor germs that could make you sick- check out my blog article on Dirty Mouthguards.
Overall this mouthguard has a pretty average fit, it just isn't as good as some of the other mouthguards currently available.
Pros + :
Chew resistant material
Hydrophobic material (won't absorb water)
$32,000 Dental Warranty
Latex Free
Can fit the mouthguard using the microwave or boil-n-bite technique
Tight fit
Microwavable or Boilable for fitting

HOW I (The Author) TEST MOUTHGUARDS & WHY I CAN BE TRUSTED
My name is Ken Mitchell. I Have been fabricating custom mouthguards for more than 15 years and have been a dental technician for over 20 years. I also, have owned my own dental laboratory for over 20 years.
Besides having work experience with mouthguards, I know first hand the importance of mouthguards in the sports world. I have played several sports throughout my life at the hight school level, including basketball, football, baseball and beach volleyball. I am also a father to two sons and a daughter who have played Soccer, Football, Basketball, Volleyball, Lacrosse and Baseball ever since they were in the first grade. From time to time I have used my children to test mouthguards to get a first-hand, real-world experience with custom mouthguards and store bought mouthguards.
I search for every mouthguard on the market. Then, I purchase (with my own funds) every mouthguard I review through places like Amazon, eBay or directly from the manufacturer, just like you would, then evaluate every mouthguard based on my expert opinion. I also comb the internet to find other reviews on durability to develop a better understanding of specific mouthguards pros and cons over an extended period of time.
Every mouthguard I review, is fitted and examined by me. The only time a mouthguard is fitted by another person besides me, would be my son, who plays college football. I use him mainly to fit and use mouthguards for weight training and football.
When I review a mouthguard it must pass certain criteria to rank in my top 10.
FIT- I believe this is the most important factor in evaluating a mouthguard, because without a tight fit, all of the other criteria can be thrown out the window. When wearing a mouthguard you shouldn't have to clench your teeth to stop the mouthguard from falling out. It should fit as tight as possible.
Comfort- Comfort goes hand in hand with the fit, if the the mouthguard is comfortable you wont get distracted by focusing on your mouthguard, instead you will be focused on the game and perform at your highest level.
Protection/Tooth Coverage- With advancement in materials, mouthguards that are thick, aren't necessarily more protective than thinner mouthguards. Brands like SISU and Game On, provide thinner mouthguards that are 40-100% stronger than EVA (ethylene vinyl acetate) that is used by most mouthguard manufacturers. A proper fitting mouthguard should cover at least your first molars to provide adequate protection. A mouthguard shouldn't extend past your second molar because it could trigger the gag reflex. Also, your mouthguard should cover your gums or the roots of your teeth.
Sport- Almost every mouthguard on the market is made for use in multiple sports but there are a few mouthguards that are designed for weight training or exercising. I will break down which sport each mouthguard is better for.
Design- I examine the color variations available and the overall design of the mouthguard, the bells and whistles if you will.
Fitting process- Most boil-n-bite mouthguards are fitted with the same process, although some fitting processes are more uncomfortable than others.
Remember to always take into consideration that every mouthguard may not suit your specific requirements. Each person is different and everyone's mouth is unique to that person. The Mouthguard Review can only evaluate the initial fit of a mouthguard and only "real world" use can show long term durability and other design flaws.
