Light, lighter, e.s.concrete light: both the shorts and also the trousers have a material weight of just 170 g/m² making them true lightweights but also extremely durable. The secret lies in the classic twill weave that is reinforced with tear-proof polyamide fibres. Strong, durable, wear-resistant – a material of the next level! Thanks to large amount of stretch material, the concrete pants are also extremely comfortable and flexible. Subtle details: the innovative slide system for up to two tool bags that is almost invisible on the waistband. And the reinforced knee zones in a stealth look cleverly conceal the opening for the knee pads.
