This REI Co-op base layer acts as your second skin, engineered from a recycled polyester blend that pulls moisture away from the body before you even notice it building up. When the ascent gets steep and your heart rate climbs, the half-zip provides an instant ventilation valve, letting you dump excess heat without needing to pause or shed layers. The flat-seam construction ensures that your focus stays on the crag or the trail ahead, rather than dealing with the irritation of pack straps rubbing against your shoulders. \u003cbr\u003e  \u003cbr\u003e\u003cstrong\u003ePRODUCT CONDITION\u003c\/strong\u003e \u003cbr\u003e  \u003cbr\u003e\u003cspan class=\"UnNewText\"\u003eThis UnNew \u003c\/span\u003e\u003cspan id=\"displayNameDesc\"\u003eREI Co-op Lightweight Half-Zip Base Layer Top - Men's\u003c\/span\u003e is in \u003cspan class=\"condition\"\u003eExcellent\u003c\/span\u003e condition.  \u003cbr\u003e  \u003cbr\u003e\u003cspan class=\"conditionText\"\u003eProducts in Excellent condition have seen minimal use and wear.
