Which bladder for Enduro Bibshorts?

Hi guys,

Quick question regarding Canyon apparel, i.e. Canyon‘s Enduro Bibshorts with D30 Protector

https://www.canyon.com/en-de/outlet-bikes/gear/canyon-enduro-bibshorts-with-d3o-protector/9101607.html

I am primarily interested in these bibs for the reason that you can apparently use a water bladder with them (without the need for a separate back-pack).

Can any of you share any firsthand experiences with those bibs?
What bladder can you recommend for these?
How comfortable are they on longer rides and in warm/hot conditions?

Thanks in advance, have a safe ride!
