Timothy ★★★★★ Oct 25, 2026

The heather gray fabric is super soft and comfortable right out of the package. The patriotic boxing shorts on the mufflerman design pop nicely against the shirt.

Abigail U. ★★★★★ Oct 23, 2026

The graphic of the mufflerman in patriotic boxing shorts really pops against the heather gray, and the shirt fits true to size without being too tight.

Benjamin ★★★★★ Oct 20, 2026

The graphic print held up perfectly after its first wash—no cracking or fading at all. The fit is true to size, and the heather gray color looks great with jeans for a casual everyday look.
