This is a great gun case. It holds my gun, hopper, and maintenance tools(allen wrenches, oil, screwdriver, squeege). Its also very cheep i got mine for about $18 and its has lasted me a year. The only problem with it it dose not have heavy padding. The padding is very light. Also, has Velcros that can hold your gun down. They hold it down good!
Conclusion:
If your a begginer and low on cash i highly suggest this and its totally wors the $18-$20.
if you want to carry your mask and tank and other stuff. Dont buy a gear bad use a sports bag they are cheeper and work just as well.
