OK, so this is another Pannier thread, but it's one with a difference.
When researching the equipment for my current tour I looked into every possible source of panniers on the market. I eventually got the ones that were in budget range, suitable for purpose, water-proof, ease of maintenance and repair, and roomy.
I never saw these ones (see picture) at all. Guaranteed to be 1000% water-proof. Easy to repair (with a large tube of glue). Definately bright and visible, and will hold about 200 ltrs each. Excellent storage capacity, and as you can see they have smaller front pockets attached also.
There is one slight down point with them. They are a wee bit heavier than the usual ones you see.
