Complementing well as an independent Gigbag sensitive

I 'take this gig bag to complement my 3 gig bag backpack in which me a removable foam bag is lost. Instead, I put my Bach B in this gig bag in the backpack fits beautifully.
But a stand-alone, it would be inappropriate because it offers little protection. In addition, my dt. B-Trp fits due to the large cup into little, so is not suitable for instruments with a larger bell.
For the price and intended use purpose wonderfully, who looks for a secure gig bag for transport, but should rather spend a little more.
