With the Treeline Rain Shell clipped to our pack we're ready for nature's surprise tantrums. When the first fat raindrop splats our cheek and the wind starts to howl we quickly shrug into the watertight jacket and cinch the hood tight just as the sky dumps. The pack-friendly hand pockets keep our snacks and topo dry while the adventure-ready design moves with us as we push onward through the sideways torrent.
