In support of Marc Lobliner and his appearance on the military-inspired competition TV show, American Grit. Tiger Fitness and MTS Nutrition has come together to launch an American Grit themed tee, which puts a patriotic spin on the MTS “M” logo. As you can see above the shirt features the brand’s “M” filled in with a grunge styled flag. Tiger Fitness has actually priced the MTS American Grit tee very competitively at just $9.99. There is also a wide range of sizes available with small all the way through to XXXL.
