Rear Rack Bag
 

I am a huge fan of my 31L Ortlieb Moto Rack-Pack. I custom-made the rear rack to suit it.

My only complaint was that it was inconvenient to carry when I got off the bike, and I always had security concerns for its content (laptop etc.) and a dislike for PacSafe mesh.

I tend to leave panniers on as much as possible (tools, spares, food, camping gear) and always take the soft-bag into tent / hotel etc. and then I get nervous when the bike is parked and I'm off sight-seeing (I run a steel wire rope w/ lock through jacket sleeve, helmet triple-grip).

Anyone used the Ortlieb backpacks or can recommend an alternative easy-to-carry fully waterproof soft-bag?

Which ones are worth investigating further, and can be conveniently tied-down?

If you research ride mag best buys there are literally loads of thesesoft bags on the market now in loads of sizes. I use a givi one 40L, but Oxford and several other companies produce them so I guess its down to cost and colour.

I've been using one of these for ages:

The backpack rig is a few clips and velcro, fully detachable - otherwise the thing is a perfectly good speedbag. Have taken it through heavy rain with no leaks.
