To put this vest to the test, we took it to the Dolomite mountains in northeastern Italy. There, we trekked through the mountains, scaled verticals and explored caves. The verdict? The loose fit made layering easy, the water-resistant fabric was ideal for fording streams and the adjustable details helped dial in the perfect fit. [] Product Details:Dolomiti internal woven label.
