Panniers for bikepacking and commuting

Hi all!

So I love cycling and I want to get into proper bikepacking. So far, I have only done short trips couch-surfing with a backpack. I also commute over 20 km most days of the week and my backpack makes my back sweat like a pig.

Therefore, I thought that panniers might be a good option for me; they are cheaper and more flexible than proper bikepacking bags, but more comfortable than just a backpack. Besides, I do not really intend to go on trails, I prefer roads and light gravel (my bike is just a racing bike with 35mm tyres).

Do you have any recommendations for good panniers that will work for commuting and bikepacking? I live in the Netherlands, so waterproofness is also rather important, as I need to carry my laptop, iPad, etc.

I found this one from Decathlon, but I would really appreciate some opinions.

Thanks for any ideas!
