I’ve had the Sync double roller bag for some time. It survived max loading, (I may have even brought two pair of poles) and throwing on multiple trains, Amtrak, Swiss, and French trains. Not sure how I survived that, but the bag was fine. You’ve got to move fast, throwing luggage around. Also, it’s freakin heavy on the handle, when your rolling it down the street. Or the sidewalk in Paris and Geneva plus some towns.
The last few years I have not taken skis.
Last domestic trip I took three pair, but one pair plus one ski had no bindings.
It’s adjustable length. Never had TSA mess with that part, and they open it every time.
The only thing that's broken is one of the plastic clips inside for the ski tie down. It’s annoying in that it is way at the bottom, and sewn in, so not easily replaced.
I think ski tie downs are important. You can’t pack that many clothes and stay under weight. I also had the airlines melt through a bag, ruin a ski binding and melt the synthetic clothes nearby.
