Overall, this is a great looking and spacious duffel bag. I searched for awhile and could not find anything with these dimensions on the market, at least not without bulky wells and the added weight. And if I had, I doubt the price would have been as reasonable.
I purchased this as a coach's bag - skates, helmet, gloves, play board, etc. Smaller skates (up to about size 9 or 10 senior maybe) can fit into the end pockets, leaving you with a huge amount of space in the main compartment. Otherwise, the skates, helmet and gloves will easily fit in the main compartment with plenty of room to spare.
I can't yet vouch for durability, though it seems tough enough. But I would have liked to have seen a slightly thicker fabric. Zippers seem rugged enough and run smooth.
The main and perhaps only real drawback is the lack of an internal pocket for keys, whistle, personal items, etc. I don't think it would have killed RBK's profit margin to add at least one and preferably two. The only other minor gripe is the shoulder strap is really long. you can shorten it to get the back up to your lower back but only with a bit of tugging the metal bracket through the should pad itself. Otherwise, the bag hangs by your knees (which some probably like). But overall, I'm very satisfied with it thus far.
Dimensions are accurate.
