You know I have to chime in when called out like that haha.
We do agree though that Merino is always better. I just wear more UA stuff because it's not nearly as fragile.
UA just flat out works for me. I also like compression layers, not just from UA either. Nike's stuff is actually good too, but I refuse to give them my money lol.
I really do notice that I'm not as sore when I am wearing compression layers the next day.
I agree I used to rock mostly capilene or merino but that stuff is definitely delicate. I actually use a synthetic base layer from Eastern Mountain Sports called Techwik. Similar to UA they have three versions T1 to T3. The T3 and maybe a fleece vest or puff vest is enough to keep me toasty up on northern VT or Maine. Definitely more durable stuff compared to merino.
