Style of fit is a personal choice for many people who exercise - there are benefits to both compression and loose fit.
The majority of people like to wear compression on their legs (whether shorts or pants) along with socks and prefer a looser fit on their upper body. Many people who play sports involving equipment (think ice hockey, football, lacrosse, etc.) wear compression tops and bottoms under their gear to encourage blood flow and enhance performance.
The coolest part is that everyone knows themselves best, and no matter what your unique preferences and athletic outlets are, Zenkai offers every anti-odor style to fit your needs!
