La Sportiva Sierra Skirt Short The Sierra Rock Short by La Sportiva is just the right choice for long days on the rock! These climbing shorts use an environmentally friendly mix of recycled cotton and hemp, which offers optimal moisture management and a pleasantly soft wearing comfort. The small amount of stretch makes the trousers nice and supple and, together with the gusseted insert, ensures maximum freedom of movement. The elastic waistband further increases comfort and can be adjusted with Velcro to guarantee a snug fit in every situation. Two open front pockets and a zippered back pocket round off the climbing shorts perfectly.
