So my workweek/travel EDC is an S25 (black Halcyon or aubergine 525)...

However, I've got a lovely S19 in deep blue 525 that gets relatively little use. I'm going to be heading to Austin, Texas in a couple weeks to see my brother and his five year-old twins, and I'm thinking of bringing my S19 as my daily carry.

I'm a little concerned though, because I'm used to carrying everything and the kitchen sink in my S25, and the S19 is obviously a smaller pack. If I leave my laptop at home, it's an easy enough transition, because that's a big device and its associated charger that I won't need make room for.

Any of you S19 aficionados able to offer advice on how to downsize from the pack's bigger sibling?
