Decathlon Quechua back packs

(Edited)
I've never checked out any Decathlon gear, but it looks tempting to go and check out backpacks. I need a big day pack for winter walks in Tassie, including off-track ones. Before I spend half a day to visit a store, I'm wondering if anyone has used their day/small overnight packs. It needs to be reasonable quality to fit the bill. I have an odd back, and haven't been able to make any more common brands of the right size work.
Ta for any info.
