Crafted from a dense 400-weight merino interlock knit, this robust layer wraps you in exceptional insulation without bulk, making it the bedrock for serious cold weather endeavors. Its pure merino composition naturally resists odor, deftly wicks moisture, breathes with your effort, and instinctively regulates your core temperature, maintaining its thermal integrity even when damp—a critical advantage on multi-day backcountry expeditions or stationary waits during deep winter hunts. Thoughtful details like chafeless flatlock seams and inherent flame resistance ensure comfort and peace of mind when pushing limits, while essential UPF 50+ protection guards against high-altitude sun. This is gear for those who understand that enduring comfort in extreme conditions isn't a luxury, but a necessity for deeper exploration.  \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\"\u003eMinus 33 Heavyweight 400 Thermal Shirt - 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.
