I was planning on buying some merino boxer briefs and that got me thinking. Do most guys wear underwear under their merino bottoms? I always have but not sure it’s necessary.
Nope, as long as you won't need to take off the merino long johns during the day due to heat. There's no difference between the length so why would you wear something underneath?

It also helps keep the stink off the base layer on the multi day trips. Its a lot easier to carry an extra pair of underwear (whatever type you wear) than fouling up your base layer bottoms.
ExOfficio is the winner for me. It’s all I wear. First layer always. I set an alert with a price tracking site for amazon and also Costco had a limited run of inventory 3/$25 last year.
I never even knew what monkey butt was until I tried those ex-officio synthetic boxer briefs. Went right back to merino under my merino base bottoms and all is well again.
I've always used ex officio exclusively but just picked up a couple pair of merino boxer briefs from FL...man they are soft and feel great, I have put them away for hunting use only though as I am concerned for their longevity with multiple washes.
I always wear my merino boxers when hunting. I may or may not wear a base layer.
Earlier this year I was hunting Coues in MX. Some of us were helping glass for another hunter who had not yet tagged out. One day, late morning, I looked to my right. The hunter was bent over and removing clothes. He was not wearing underwear under his base layer. This hunter was also up there in years and gravity was unkind. That was a most unpleasant site.
