Men's Kiln Boot Top Bottom

Midweight 250 Merino-X


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.

A littler short

Great piece, Warm and comfortable. I do wish they were just a little long so I could use the with a shorter boot/sock combo. You can always roll them if you needed to make them shorter. I'm marking the fit as perfect because I believe they fit as intended.

Very warm!

Comfort is unmatched and incredibly warm! I can’t say enough good things about the material and the way it performs. I never want to take them off.

I owned the Allegheny suit, then sold it and bought this when FirstLite came out with the new version. The design change did what it was intended to do, added structure to the garment for a better fit. The old version would sag a little especially after wearing a while and become a little unstructured. The merino X version is great, warm, soft and itch free. And I really like the chest pocket. Perfect weight for November rut hunting in the Midwest.

Incredibly Layering Option for Southern Hunters

I hunt in the deep south, and temperature fluctuations are a serious issue. It is not unusual to hunt one afternoon in 70 degree weather, and wake up the next morning to find its 29 degrees and windy. Having been convinced to go the wool route by my uncle who hunts out west, I purchased these pants for those chillier days, especially when there is a good wind. I have hunted with these, and my Obsidian pants on several very cold mornings (25-30 degree days) and I have found them to be a tremendous combination. The Obsidian pants alone are comfortable in lower temps, and while these are not wind proof, they are so warm when combined with the pants, I find they are perfectly suitable for that temperature range. I would highly suggest these to anyone who hunts public land in the deep south as a light and packable option to slip on having walked to the stand!

Perfection as a layering piece for a whitetail stand hunter

The boot cut eliminated the hot, sweaty uncomfortable bunching you get around your heavy winter boots and socks. I think this makes my feet warmer, especially when I have a hike into the stand. When it gets really cold (below 20 degrees with significant wind), I will add an additional fleece layer between this and my Sanctuary bibs. What I like most is the sheer comfort and excellent fit of this piece. It fits snugly but doesn't constrict in the slightest. It feels like I'm wearing nothing at all.
