The Lone Peak 4 Mid RSM is made to face the elements. Features a brand new eVent® upper, which offers leading breathability, maximum comfort, and protection in the widest range of conditions. This new fabric material is also lighter and more durable than our previous version. The 4-point GaiterTrap™ and fresh mountain design complete the upper, while the updated, multi-directional lugs on the outsole bring you optimum grip.
