It's too TOXIC out there!
In recent years the sports and leisure industry has seen a major increase in the use of technological fabrics that have given significant protection to the end user.
This increase in the use of modern fibres together with European legislation in particular, the PPE Directive, (Personal Protective Equipment) has seen improvements in the safety aspects of many sports activities with positive results being achieved in the ever competitive and commercial world of sport. Respiratory protection is seriously being considered and now being used in many sports activities.
Hey! if the lungs don't function properly you ain't gonna win and second is nowhere.
