I have had my split roller since 2001 when I first took it to Alaska. It continues to go strong to this day. The dual comapartments provide ample room for all your stuff - and the separation allows you to put wet stuff in one side if you are packing up at the end of a ski/windsurfing trip and then hopping a plane. I don't mean to say it has a neoprene compartment though - there is just good separate spaces. The rollers were a big deal 8 years ago, pretty standard now, but the wheels have held up great. Like many of my DaKine products, this will last a long, long time.
