Respro Ultralight Sand Extremely lightweight and comfortable, the Ultralight™ is made from an elastic stretch fabric that stretches in four directions and provides users with maximum comfort even during training in high humidity and temperature conditions. This is ideal for runners, cyclists, athletes and those who value equipment that provides comfort in all conditions. The Ultralight™ is the sport equivalent of the y™ , offering a more "competitive" usage profile - but also suitable for y sufferers, especially those who do not want to give up their active lifestyle despite their ailments. The main difference is the type of valves used. In the case of the Ultralight™ , it is equipped with modern Powa™ Elite valves, which ensure optimal airflow even during intense physical activity. The set also includes a special Hepa-Type™ filter which, thanks to electrostatically charged sub-micron fibers, effectively catches even the smallest particles, dust, bacteria and fungi.

It comes complete with a practical hood pouch. Note: This is not intended for use in situations where compliance with the European directives 89/68 and 89/656 is required.
