High visibility. An essential feature when you are working along or in the vicinity of a road. The 1SNS combines high visibility in accordance with EN ISO 20471 class 2 with the specific characteristics of the Progress range: comfort and durability. Wearing comfortable clothing increases your well-being and your productivity. That's why we used the qualities of the Progress range (Armortex® Light, TeXXion, Teflon™...) for this pair of hi-vis trousers.
