Action3® is a technical composite material developed specifically for the hot season. Body perspiration, generally about a third of a litre per night, can considerably increase with the use of unsuitable products, causing discomfort and disrupting sleep. Action3® is the solution to this problem: it combines cotton, linen, and anti-condensate fibres to ensure a balanced microclimate. Excess humidity is not withheld but dispersed externally. Similarly, excess heat is not accumulated, thanks to the optimal thermal exchange. The dry material also prevents the formation of bacteria and moulds.
