Iï¿½ve tried many backpack pannier combos. This one is simply the best. The conversion process is seamless and not cumbersome.
One of the straps failed and support sent me new straps that can be screwed on! Repairability isnï¿½t something I looked for but is awesome to see.
Only criticism is that I wish it had more organization.
If you can get past the ridiculous price tag, the Ortlieb Vario does exactly what it advertises -- a single pannier that can hook on to a rack or be used as a backpack. The conversion is simple and all the moving parts are reinforced to reduce wear and tear. I commute 2x a week and walk 2x a week, so this has eliminated the need to transfer all of my work stuff from pannier to backpack. The laptop sleeve is and outside pocket are much appreciated details. I'm not surprised they're sold out. Highly recommend.
