The Bonatti Trail is a popular choice for runners who don't skip a run because of weather. Its 2.5 layer structure makes it very light and compact as it has no liner fabric. We recommend pairing this jacket together with a long sleeve base layer. The Pertex Shield fabric this jacket is made of is made in Japan and is supple and light. It also boasts high performance numbers, with both hydrostatic head and breathability values being 20 000. Thanks to the special patterning, you can use a Salomon running vest/pack up to 12 liters in volume under the jacket. - Tight fit - Waterproof, windproof, breathable - Extremely good freedom of motion - Seamless shoulders - a great feature if you carry a backpack - Longer back panel - Integrated hood - Extra snap button at the front enables ventilation without opening the whole front part - One chest pocket, one security pocket - Reflective detail - Machine wash at 30ºC, don't use bleach or fabric softener
