For a long time I used the standard Decathlon bar bag which was fine, no map holder though. Upsides, cheap, light and comes with a strap for easy carrying over the shoulder when off the bike. QR mount is solid and easily waterproofable by the simply expedient of lining with a shopping bag. The gf has an Altura box shaped one which had a map holder which was ok until lots of use meant it finally came away. Not bad and pretty spacious and came with a strap but heavy and not that aerodymanic.
Couple of downsides to bar bags to be aware of;
1) You will probably need to re-rig your lighting to some extent. If the bag doesn't rise up enough to stop you mounting your light front and centre, it will almost always cast a shadow in front of your front wheel. Most audaxing for 200k and over will contain an element of low light riding for which you will need a front light.
2) Adding that weight over the front wheel can cause feedback and different handling which isn't always pleasant. In slick conditions it can be a bit of a tipping point for an off.
I've now moved to the maptrap and saddle bag combo and am a lot happier with it. If daytripping and audaxing really takes your fancy then I would strongly recommend doing this from the start. Weight on the back is much more comfortable and easier to handle and you can carry a heck of a lot more if needed.
