I have had my 35L panniers for over a year now, and they are perfect. Sometimes I use them in combination with the BC40L duffle. Last week we went out to camp on the desert, and this equipment caught the eye of all the other 21 bikers, so I hope you'll get some orders from Peru soon!
I have incorporated two small Molle pouches (not Mosko's) to each of the BC 35L panniers, and they work great! Since I dont like to use a tank bag, in those pouches I keep things that I want to reach quickly during short stops (and without having to dismount) like energy gels, fruit, a cap, my sun glasses. Unless I am heading to the Andes, I dont use the waterproof inner bags; this way the panniers are lighter and have more capacity. Besides the regular bulky camping equipment, to this camping I was able to bring a medium size tarp and collapsible poles to set up on the desert. Also, inside of one of the panniers I brought a small lunchbox with frozen beers and frozen food, and after 16 hours of very hot weather, my beers were still super cold, thanks to the protection and isolation of the pannier.
Overall, this product is excellent! I also own the BC 40L duffle and sometimes I use them in combination with the panniers. And there is still plenty space for my girlfriend to ride with me.
