If you can't find the strap, it's hiding at the bottom of the 15" hat pouch.
Speaking of that 15" Hi Hat pouch, you cannot use the separators to isolate the cymbals.
They are attached to the inside and they do not go deep enough to allow you to close the pouch "if" you have 15" hats, which I do..You will have to insert them in the back of the pouch touching one against the other.
On a scale of 1 to 10 in projected durability, I'd give it about a 7.
It's real pretty though...
