When hunting out west, frost-covered mornings often turn into hot, sunny afternoons. 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'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's new Zip Off Long Johns solves this problem by allowing the mountain or hardwoods hunter to shed base layers without consternation.

The Merino-X Kiln 250 Zip Off Long Johns have set a benchmark for versatile performance during mid to late-season hunts on the mountain and in the tree. These high-loft, midweight bottoms are ideal for scenarios when cold weather is expected, but not necessarily sustained. Whether you're glassing for high country mule deer in October or sitting still for river bottom whitetails in November, the Kiln Zip Offs enable you to handle the changing elements with ease.

The Zip Off feature is also available in our Wick Boot Top and Furnace Boot Top baselayers.
