My leathers are less sweaty than my textiles so I have worn them through most of this year. If it starts raining hard I need to get waterproofs on fast or it will be too late. On an overnight or longer trip I will have a lot of carefully packed luggage, and extracting waterproofs is a pain. On a recreational ride I don’t want a top box. A small tank bag is the answer. I had a little Frank Thomas one. It was terrible, determined to move about and come off. No Headstock strap and the magnets were really weak.
I bought an Oxford X4 based on BCF recommendations. The magnets are insanely strong, and on a removable board. There are Velcro straps so it can be used as a tail-pack if required. The zips have some kind of rubbery shroud so are water resistant. There’s a satnav holder, an A5 map holder that’s just big enough for my Philips Compact Atlas or directions printed on booklet mode. It has a headstock strap too. Most importantly, it stays put really well. Right now it’s carrying my waterproof overjacket, my waterproof trousers, my goretex winter gloves, visor cleaning kit, hand sanitiser, a spare buff, a pen, an tyre pressure gauge, my disk lock and (because I fail at packing) my ledergris and boot brush. My phone and wallet sometimes end up in the top section, and sometimes I use the map holder.
It stayed put during every crazy run I’ve made since I’ve had it and feels really well made. It is quite small at 4 litres, so consider a bigger one from the same range if you want something to carry everything. For the bits of tat that I want straight away, it’s perfect. Highly recommended.
