Really nice bag that offers a high level of protection for instruments. It comes with several padded blocks which you can move around in the bag and stick to the lining allowing various configurations. I have managed to get a fold up music stand [split in to two sections] in underneath the flugelhorn, and could probably get one mute in as well. Without a music stand could probably get several mutes in but might need to bubble wrap them. Main outer pocket is plenty big enough to get a folder of music in, the smaller top pocket has spaces for mouthpieces, oil etc. The bag has padded backpack straps which are stored behind a flap of material. The main handles seem very strong, and there is also a wide shoulder strap included with sturdy clip on hooks.
