Temperatures dropping? Layer up in the Saxx Viewfinder Long Sleeve Half Zip. The long-sleeve half-zip employs a super-soft, midweight fabric to help trap and maintain your body heat when the mercury plummets. A half-zip collar lets you adjust the airflow; unzip it when you’re skinning up the mountain, or zip it up all the way to seal out drafts. With flat seams to control chafing and odor-fighting properties to keep you smelling fresh, the Saxx Viewfinder Long Sleeve Half Zip is ideal for all-day outdoor adventures.
