These Alpine Shorts perform well as classic running shorts without all the frills, while maintaining the key features for mountain and trail runs demanded by women. At only 63 grams, these shorts with a shorter, relaxed fit are the lightest shorts in the collection. Perforations at the waistband and the use of especially lightweight fabrics offer maximum ventilation. At the rear of the waistband, you find a zip pocket for your smartphone. The waist is also adjustable. Reflective stripes increase the visibility of runners off road or in less-than-ideal weather or darkness.
