From day ski tours to summer hikes, we take the Traverse 28L S dry backpack with us so that the weather does not interfere with our enjoyment of the mountains. This backpack designed for skiing in less than ideal weather conditions has welded seams and 50K water resistance, which guarantees that the contents of your backpack will remain dry even during a snowstorm or rainstorm. This allows you to wear a backpack without a rain cover , providing quick and easy access to all of its pockets.
