The Progress CC TKR men's functional T-shirt provides a maximum feeling of comfort and freshness due to the inclusion of a special Cocarber fibre. It is a top viscose fibre, which is enriched with coffee beans. As a result, the fabric uncompromisingly absorbs and neutralizes odours. It also has extraordinary antibacterial properties. Recycled coffee residues are used to produce this fibre so its production is environmentally friendly.
