These are the perfect companion to the Furnace Quarter Zip. Just like the top, they do an excellent job regulating temperature without making me feel overheated once I start moving. They're warm enough for cold mornings in the treestand but breathable enough that I don't end up sweating during the walk in.
I also appreciate that they don't feel bulky under my hunting pants. They fit well, move with you, and layer comfortably whether I'm wearing lightweight pants early in the season or adding insulated bibs once winter really sets in.
Merino wool has become my go-to for base layers because it stays comfortable all day, manages moisture extremely well, and doesn't hold odor after multiple days in the field. These have become a staple in my hunting gear, and I wouldn't hesitate to buy them again.

Very nice pair of long Johns. My son has had these for a couple of years and swears they are extremely warm and comfortable. I look forward to getting use out of mine.
