Gasp Logo Mesh Shorts are the business for the summer no matter what your doing, the heavy mesh fabric is great for gym use, running, cycling, martial arts or anything else you can think of.
The material doesn't hold sweat like other fabrics do so any perspiration dries off really quickly due to the clever "pores" in the material.
These will stretch to allow free movement but will not go baggy and shapeless like most regular shorts do.
