Pants recommendation

Hi all, I am looking for the perfect pant😅 I need a new since my old one broke down. I am mainly doing skitouring with scrambling climbing, and also I started this season with some ice climb. Specially, I would need to have crampon compatibility (aka the straps in the ankles), possibility to open the legs completely, waterproofness, robust and if possible a removable bib.

I would love if anybody could share some recommendations. I have been checking and so far due to the pricerange the simond functionspants are on the top of the list.

Thank you all
