Bad weather is no longer an obstacle when you wear the Bonatti Trail Pants for your run. A matching jacket is also available in the same series. The front panel of the pants features a 2.5-layer construction: there is no loose lining inside, making the pants very lightweight and easy to pack if needed. In winter, you can wear long base layers underneath, and cold snow or sleet won't interfere with your runs. The front panels use Pertex Shield fabric, made in Japan, which has gathered many fans since its release. It is flexible, lightweight, and offers high performance (20/20, meaning both the water column rating and breathability are 20,000). - Slim fit - Salomon Hybrid Technology - Waterproof fabric in the front: Pertex® Shield 2.5-Layer Ripstop 20K/20K - Air-permeable, slightly water-repellent stretch fabric at the back - AdvancedSkin Shield: technical solutions provide comfort and keep you dry and warm - Laser-cut small holes in the fabric improve ventilation effectively - Adjusta
