Salomon's designers are runners too, so running pieces like the Men's Trail Twinskin Short are rife with clever design touches and features. On the outside, this lightweight short features an understated style. On the inside, the Twinskin features a stretch liner that not only provides support but also moves moisture away from your skin. And where the inner short and the outer short intersect' Salomon's designers cleverly combined the short material to eliminate the opportunity for chafing that could slow you down during a race or training session. You get the performance of a liner short and the style of a trail short without sacrificing for the benefit of either.
