It’s the original bag from pro team.
Very Strong. Perfect for my vacuum, also a pro team brand.
Those bags are made for a specific type of vacuum(proteam super half hip/backpack vacuum).
If you don’t like to deal with dust and mess, you can just change the bag when it is full, but if you like to save some money, and don’t mind dealing with a messy full bag, you can empty the bag and use it again.
I recommend this product.
Very good.
