This is the best double-instrument trumpet gig bag available anywhere! The bag is longer than any other double-bag that you can find (see internal and external measurements of the Tom and Will website), which means that virtually any trumpets or flugelhorns that you own (including the extra-long ones) should easily fit in this bag without having to squeeze and force them in (which is bad for both the instruments and the bag.) Before I got this bag, I had to cram my extra-large 4-valve Getzen Eterna flugelhorn into my old double-bag, which always put stress on that old bag and its seams (which were tearing and giving way.) And, there is also plenty of room in this bag so that I don't need to push in my flugelhorn's tunable lead-pipe like I always had to with my old bag. (For me to play in tune on it, my flugel's leadpipe is always pulled out quite of bit since I use a fairly small/tight/efficient mouthpiece on it, a Parduba 4. 5 FL, which I use to make extended upper-register playing easier on it. There's even room in this bag for me to leave my mouthpieces on the instruments when they're in the bag, if I want to. This actually comes in handy for any rehearsals that I don't want to bother setting up my instrument gig stands for: I can easily just take the completely-assembled instruments (including mouthpieces) in and out of the bag if I want to, instead of having to use my instrument stands (Which is sometimes a real time-saver, especially if I have to rush off to another gig or something after the rehearsal.) This bag is also ruggedly-built of high-quality materials, with very strong stitching which I expect to last for a very long time. And, I am especially impressed with how well-padded the bag is, providing great protection for the instruments. I love the backpack straps feature, and the bag is brilliantly-designed so that when you are wearing the bag backpack style, you don't feel an instrument pressing against your back like you do with so many other bags. (I have another, older 5-trumpet bag made by a famous maker, and when I use that old bag, I can feel the bell rim of one of the instruments in the bag pressing and cutting into my back--ouch! This does not happen with this Tom and Will bag.) If you don't want to use the backpack feature, you can easily tuck the backpack straps away nicely out of sight.) Wearing this bag backpack-style leaves my hands free to easily carry a music stand and a mute bag and accessories bag. And speaking of accessories, this bag also has plenty of storage pockets for accessories such as mouthpieces, valve oil, slide grease, etc. There is a a large zipper-pocket on the side of the bag, another zipper-pocket on the end of the bag, and another, plushly-padded pocket inside the bag (which most people will probably use to hold their mouthpieces--plenty of room for several of them there.) And speaking of mouthpieces, there are two very nice, soft, well-padded, drawstring mouthpiece pouches that match the bag's interior that are also included with this bag. The inside of this bag is also highly self-customizable, since the padded-foam S-shaped instrument divider inside the bag can be adjusted to custom-fit your particular instruments, and there are even a few extra soft-padded inserts included with the bag that match the case's interior--one very long one, and two shorter ones. The bag also has very comfortable and sturdy handle, and a similarly high-quality shoulder-strap, giving you a choice of three different ways to carry the bag: By the handle, by the shoulder-strap, or backpack-style. A feature that is normally only found on hard cases, this bag also has hard feet on the bottom (and also on the end, in case you want to store the bag in that way), which also help to protect the bag. I highly recommend this bag--I love it!
