Decathlon's Forclaz MT900 for mountaineering and climbing?

Hello everybody, I was looking at these pants and they look solid. They look like your standard 3 season alpine pants from every other major brand, and the price is great. I'm on a budget and I'm considering them to replace my patagonia simul alpine pants which no longer fit me.

My other option are the OR Cirque Lite pants which are on sale at a local store.

I appreciate your thoughts and opinions, thank you!
