I'd put vulnerable stuff in a dry bag. Do you think the 20 would be a better fit for me (I am only 5'3") - thinking I may be swamped by the 25 ...I have a 20 l generally for use at leisure and not so big that when stuffed full if needed my lovely pillion can carry on her back without strain. Admittedly I have used a 25 before and has a better fitting harness like a full parachute but not so better in real terms.
Do try to get the waterproof version with the roll top. I lost a brand new ipod to water damage in my 8 hour rain journey as was at bottom of bag.
I do now use a liner in case of water ingress myself and to be fair it was an awful lot of rain continual on the way to IoM 2 year's ago. Personally yes i think it may swamp you. I don't know if any dealers have them local to try on your back but mine came from hein gericke back when they were alive and not now j and sI'd put vulnerable stuff in a dry bag.

The seat will take a 35 litre tail bag without restricting rider space, even without a rear rack, and I can do 9-10 days with a 35 litre tail bag. I always prefer the bike to be carrying my luggage rather than it being on my back.I've just seen that Demon Tweeks have them who aren't too far from me, so will go and try them on! Prob get the R20 I think :encouragement:
