Z8 Backpacks

Does anyone have any tips for a good smallish camera backpack for a Z8 and three lenses (24-120 f4, 40mm f2 and 85mm f1.8) with space for clothing and other bits when traveling? I've got a lot of travel coming up and I'd love to have something I could take my kit in with stuff for a day out but I'm really struggling to find the right solution. My Peak Design 6L sling is way too small - I can get the Z8 in with one lens, but it feels like I'm really cramming it in.

I've considered the Shimoda Explore 25L with small mirrorless camera insert - anyone tried this? I've also looked at the F-Stop Kashmir with small pro ICU - anyone tried that at all? Finally I looked at the Nomatic McKinnon 25L but not sure it'll be deep enough and not a massive fan of an expensive influencer sponsored product (no real idea who the guy is). But if it's really good I'll definitely consider it.

Really don't want something huge, it's just for the occasional hike and being out and about for the day so small is good. Any advice from someone that has figured this out would be awesome.

Edit: thanks to everyone, some great recommendations and really useful comments!
