This is a lightweight collapsible container with a very strong carrying loop and velcro straps to hold it collaped. We reinforce the basic bag with heavy-duty duct tape at tear points. These are the perfect size for 33 gallon trash bags which is our 'standard' bag size.
After trialing heavier, better quality bags we kept coming back to these because they're lighter, just the right size, and pack down well. So we compensated for the flaws by reinforcing the tear points to make them last better.
This bag is an upgraded Gladiator collapsible bag available at any Ace Hardware Store.
