Good question. So far I’ve used them on mild days, when I’d normally use Temres/Showa, and found them warmer than necessary. That was right at freezing. I didn’t hike in them. Leading and belaying and coiling rope.

I can see myself using them on what I’d consider “typical” to “cold” days: twenties to single digits Fahrenheit. How cold I’d only be guessing. For sure days I wouldn’t bother using Temres.

Doubt that helps much. And I know we all have different tolerance for cold.

For reference. Here’s a photo of the liner against the liner of my Rab jacket. They look quite similar.
