The mute bag has ample space for a Harmon, cup, straight and plunger, but, if I'm also carrying a bucket mute, I put it in the wider end of the middle trumpet compartment

Side and end pockets provide ample space for mouthpieces, spare lead pipe, valve oil, cleaning cloths, music and notes and other miscellaneous items

If you only have one trumpet, you'll love the space for your folders, items and mutes, and you may need more than one trumpet in the future at an engagement.

If you are hoping to carry, for example, a B flat, a C, and a flugelhorn, it might not work as well
