In whitetail country, cold mornings can turn into cold sits without proper layering. Long johns are a no-brainer for both situations, but with temp swings or long distances to the stand, the hunter often finds himself overheating halfway through the morning&apos;s walk. Taking base layers off on the hill or before climbing the ladder involves taking off boots, dancing out of pants, shedding long johns and then replacing the pants and shoes. First Lite&apos;s new Zip Off Long Johns solves this problem by allowing the mountain or hardwoods hunter to shed base layers without consternation.Our Furnace EXP 350 Merino-X fabric incorporates a brushed (fleeced) backside to our high loft, interlock knit to provide super-charged insulation without added weight.
