Men's Kiln Boot Top Bottom

Midweight 250 Merino-X

$85.00 USD

Color/PatternFirst Lite Cipher

From September elk to January mallards, the Men's Kiln Boot Top is our do-it-all bottom. 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 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 Men's Boxer Short, Quarter Zip Top, and Crew Top.

Fit Comments: I mainly use as 2nd layer over the fuse if I was to use it for base I’d want smalls to fit tighter

Great white tail gear

I purchased the kiln bottoms and I am very pleased with them they keep legs toasty and dry and like everything else I have from first lite is made very well

Fit Comments: I usually wear a 35” waist in Wranglers for comparison
Warm but short

Warm and comfortable, but too short. It doesn’t take long for these to ride up, and wad up above your calf. Maybe if you borrow your girlfriends knee high socks you might keep them in place. Waist and everywhere else fits perfectly.

Must haves for snowshoeing

Ran these for three straight days of tracking cougars on snowshoes and they were perfect. Wore them under corrugate pant and brambler gaiters. The calf length is awesome because they don't get pulled down from the lower leg like full length base layers with the combo of gaiters and snowshoes. Highly recommend for high activity base layer.

I wasn’t a fan of the boot cut at first, but once I got some over the calf socks I quickly changed my mind. I wore these in temps ranging from 50 to below 30 and they performed well.

Thin and warm.

I bought the kiln top and bottom for an Alaska trip next year, but decided to try it out in a tree stand in Michigan. When I got it I thought I’d be duped, it was soft beyond all reason, but very thin. I was wrong. It’s insanely warm for how thin it is, now I’m wearing less layers in the stand and just as warm.
