Do Pants Matter That Much for Alpinism? (Beginner Question)

Hello everyone,

I’m taking a beginner alpinism course this year, and I’m wondering how much the choice of pants actually matters. I have a pair of Fjällräven Keb pants, and I’m pretty sure they’ll work fine to start with, but I just wanted to hear some opinions from more experienced folks. Do I really need dedicated softshell/alpine pants right away, or will my Kebs be enough for a beginner course?

Any advice would be appreciated! Thanks!
