The Ridgeline Base Layer Top is a next-to-skin base layer containing a super soft Merino wool/polyester blend that will quickly dry and wick moisture, even during high levels of exertion in the field. The premium Merino is also anti-microbial and retains its insulation value, even when wet.  Heavier version also available for even colder temps (see Ridgeline Heavy). Designed and field tested with outdoor expert Aron Snyder.
Conditions: Cold - Frigid (Paired with Mid-layer and/or Outer Layer)
