I need to replace some cotton base layers in my gear closet. I’ve been reading a lot about Merino Vs Capaline. Seems like Cap is slightly better. It’s honestly 50/50...

Anyhow I think I’ve decided to try Capaline. But if it’s a synthetic fiber, what is the difference from 100% polyester thermals from target or something? Other than about $100 dollars. Lol.

If it helps my temp range I need to cover is 30* +. Mostly 40+.

Thanks gang.
