It is not written in the description, but the case includes a triple mouthpiece case! Really soft and smooth, I keep it inside the case close to the bell of my trumpet without problems.
I use to carry 2 standard bell trumpets, the case is firm enough and the zip are good, backstraps with a nice padding.
The outside pocket is enough to store oil, grease, some scores and a 10" tablet in the same time.
Great value for the price, medium weight and good to carry one trumpet only with some mutes.
I bought it to travel mostly by bike and I am really satisfied for this.
Cons: it is a little bit higher and deeper than the allowed size of the airplane hand luggages, but I traveled with it several times and I never had a problem.
