Removing greenbriar and other vines from an overgrown property. Needed sturdy bags to withstand the briars. The briars still poke through the bag but the bags hold together far better than lesser bags we've used. My wife often drags the bags across the terrain when they are too full to carry. They hold up great!
I use several boxes of these bags every week and I have never had one break or tear. I had problems with other brands of bags of a similar thickness and price range where the bottom bursts open upon lifting heavy loads. I am also able to drag them across the ground without spilling the contents.
I was doing a demo project on my house and had to bag debris. The cheaper bags did not hold up to sharp edges and tore frequently. The Husky ones were labeled as 3 mil thickness like the other ones, but they held up much better!
These bags have separated, stored and transported everything without a hitch. Its nice to know that even though you have overloaded the bag it is not going to break or tear when you move it. For storage we marked them with a white pen.
