Once again, I went in to the shop. I told them I wanted a bag, why not this £50 over here rather than the - gulp - over £200 one. The guy showed me both. We did everything except consummate each bag. It was no contest, and I walked out with this one. I commute. I need to take a pair of trainers, a set of clothes a bike chain, my laptop, my glasses, all my passes and toiletries and sometimes a shower. When I get to work, my big bike trousers, my biking boots, my gloves, all need to disappear. This bag takes it all. The zips look like they could stop chernobyl, and I pull those things with wanton violence. The laptop compartment is roll top and so stupidly obvious and effective, I can't understand why everyone doesn't so it. I've got more cubby holes and pockets than James Bond. It's ridiculous, it's brilliant, I love it. Chest clip and waist clip. Adjustable everything. Super solid build and comfy af. Absolutely worth the money. Go get one.
