I have a camelback mayhem 3l which is a few years old and very large. A new bladder is around £30 so thinking of getting a new smaller camelback for around £50 Ebay price.
On the mayhem it has a padded zip pocket I like for my iPhone and a clip in the bottom pocket I can use to never worry about dropping keys on trail when looking through bag.
Pefect bag would be
Smaller than mayhem
Clip for keys
Space for multi tool,snack and wallet.
What can you recommend ?
