I love the Kriegas. I might get a Mosko 80L Reckless for "heavy off-road camping trips", but the Kriegas ability to combo bags to allow me to tailor my kit to my trip (style, duration) is great and I highly recommend them. In this kit, I was carrying 30L + 2x20L + the water/fuel bottle carrier.
I’ve done a few BDRs with the Kreiga bags (32L + 22L + 12L) with absolutely no issues. I’ve low sided through a deep puddle, dragged it through a rocky stream after running aground and dropping the bike, and rode through a typhoon at highway speeds.
Absolutely no issues with durability or water proofing.
I put all my clothes in the 32L, my laptop in a pelican case and other misc (mini-pump, plugs, first aid) in the 22L, and all my camping gear in the 12L. I strap the tent to the top of the 32L with some rokstraps.
