The Alpine Pro 2in1 Shorts are light, comfortable Trail Running shorts. Stretch allows the integrated mesh liner to fit comfortably, and flat seams offer great comfort and good ventilation even during demanding runs. The breathable outer fabric has perforations to ensure increased air circulation. For a great fit without binding, you can also individualize the fit of the elastic waist with its drawstring adjustment. Two mesh pockets on the back and a zip pocket give room to stash gels, energy bars or a smartphone. A small pocket on the inner liner can also accommodate a key. Reflectivity increases visibility of runners on trails or in unfavorable weather conditions and the dark.
