This is exactly what Evoc's nylon 210/D ripstop offers. A double PU-coating of the lightweight nylon base provides moisture protection and wear resistance. A micro texture of filaments segments the basic fabric into tiny squares to prevent rips – hence the name ripstop P600 D PU Coated: A very durable fabric for high-abrasion areas, it is also tear-resistant and lightweight while absorbing almost no moisture. Combining these characteristics, it’s the perfect material for high-stress pockets or backpack base constructions Air Tune System: The lightest back system for Evoc's lightest backpacks. The Air Tune System offers minimal contact surface and maximum back ventilation for high-performance use Ventilation channels, 3D air mesh padding and shoulder straps with ventilation holes make up the key features for maximum breathability when every second counts or simply for that little bit of added comfort Air Circulation: This is used in all Evoc's backpacks, as it ensures optimum ventilation while preventing excessive cooling down of the sensitive kidney area, even during extremely high-strain activities or intensive perspiration.
