Haven't tested it out yet but the quality seems to be there. Had one long thread that I had to cut it was connected at both ends in a loop.. hopefully that doesn't affect its durability down the road. Very roomy speeding bag. You can sprawl out a bit.. unfortunately I needed a left zip but they only came in a right zip which is hard to get used to. Hopefully after a trail run shortly I can give some more information on it. I'm 6 foot and bought the long.. plenty of room.
