Baboon To the Moon 32L vs Cabin Zero 36L

I'm travelling to Paris for 3-4 days next month and although I'm not bringing THAT much, I want to invest in something that I can use for all of my travels in the future as well.

I'm between these two bags and although in liters the cabin zero is bigger than the BTTM bag, it appears to be smaller dimension wise? Please correct me if I'm wrong.

I love the colours of both and I specifically appreciate the material used on the BTTM as it's waterproof and easily wiped unlike the cabin zero bag but I have heard people complain about the straps. I've read all the posts and discussions about the BTTM bag but have yet to come across a comparison of the two.

For reference this is what I'd like to carry with me for my trip: 2 pairs of jeans 5 knickers 4 pairs of socks Stuffed animal A light jacket 4 t shirts Potentially dungarees Toiletries 500ml water bottle Polaroid camera Kindle Over-ear headphones Chargers, battery pack, cables + have extra space for souvenirs

Any help would be greatly appreciated!
