I may or may not have reviewed RKA products, specifically saddlebag liners before. The fact that I have to think about it should tell you that I am a more than satisfied customer. To overstate, I bought these before the saddlebags for the bike came in at the dealer. The construction is top-notch: Heavy material, double stitched seams, precise dimensions to fit in your panniers, strong, wide straps for carrying, either by hand or over your shoulder. Yeah, the saddlebags come off the bike, but 1) loose items in the bag tumble around and can be damaged, 2) It's harder to find things even on the road if they're loose in there, 3) additional moisture barrier, 4) you don't have to carry (potentially dirty) saddlebags into the room or your tent. If your bike has saddlebags and RKA makes liners for them, I can recommend these without hesitation.
