From September elk to January mallards, the Men's Kiln Boot Top is the do-it-all bottom of hunting clothing. The 3/4 length successor to our best-selling Allegheny, this piece is constructed of Midweight 250 Merino-X fabric for improved structure and durability. Perhaps the most versatile baselayer component within the First Lite system, the Kiln Boot Top simply cannot be beat as a baselayer bottom for any hunter or outdoor enthusiast. This piece can be your first or second layer and will keep you comfortable and odor-free from September through April. If you're looking for a true ace-of-spades in your layering system, look no further. The Kiln Midweight 250 Merino-X fabric utilizes ultrafine, 18.5 micron merino wool in a high-loft, interlock knit to create styles that surpass expectations in the broadest range of temperature and weather conditions. Blending a small component of spandex into this knit, these lofted interlock pieces can withstand extended hunts in the field, regardless of the season. The Kiln midweight 250 Merino-X is also available in a men's Quarter Zip Top, and Crew Top.
