ACT Running BioPerf Men's T-Shirt

Combining extreme lightness with silk-like softness, the BioPerf T-shirt optimises comfort and efficiency while running.

Crafted using BioPerf nylon, the BioPerf T-shirt from ACT Running is derived from castor beans, a naturally growing, renewable resource for an environmentally friendly choice. The material is also highly breathable and allows for cool, refreshing air to circulate while removing unwanted warm air, helping to regulate temperature so you remain cool throughout your run. The fabric utilises a four-way stretch to allow for a full range of movement, providing you with an enjoyable, restriction-free wearing experience.
