The Ridgeline Heavy Base Layer Top is a next-to-skin base layer designed to be worn in more frigid conditions. It features a heavyweight, super soft Merino wool/cool pass 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.  Lighter version also available for more moderate temps (see Ridgeline Top). Designed and field tested with outdoor expert Aron Snyder.

Conditions: Cold - Frigid (Paired with Mid-layer and/or Outer Layer)
