Streams! Roots! Rocks! Oh My! On a hike it’s safe to assume you’re keeping your eyes on the trail, which can cause some unsightly and uncomfortable hunchback posture. Our Wingtech short and long sleeve shirts will straighten you right up, comfortably! The wings on the back of the shirt gently adjust your posture to optimize your form, therefore optimizing your breathing. So while you watch your step, we’ll watch your back.
