I have the older one. I meant to send it back as it’s the 1st Gen with the bad straps, but it’s been a while so I may just start using again. The current one has better straps.
Anyway the size is very good for wallet, couple bars, wind jacket, phone, keys, key sundry tools. I got a sandwich cut in half in there before.
The construction is good and the material very good, the pink lining is nice to finding things. I wish it sat more forward than under because of my cables - canister bag would probably be nicer there. Never ever used the shoulder strap.
Those canister bags I think are one big pocket? It’s nice to have a slim front pocket on the rapha bag, and the main pocket has a couple organiser pouches.
30 quid is a bargain to be honest
