But I'm just a soul whose intentions are good

Archival Clothing is a favourite blog of mine, and I've just stumbled across their musette, made from waxed cotton and with an attention to detail rarely seen in similar bags today. Definitely a more rugged appearance than the Rapha version. Looking for an alternative to your messenger bag if you don't need excessive literage when you step out? An Archival Clothing musette could be what you're looking for. Have a look at it in more detail on the Flicker set, and here's the lowdown from Archival themselves.
