Base layer guidance needed

[JakeV117]

For any of my distance walks, either for hunting or fishing. I like to wear a light weight pair of pants, for the hike in, early season i try to wear something with a bug repellant in them. Then either change into my insulated pants, or just add a merino base layer. I wear merino for 40+ mile backpacking trips, all day sits, and fishing in colder weather. It's amazing stuff.

I really like the Kuiu Merino stuff, but have also used other brands like Simms and Smart Wool.
