Nice! With the best will in the world I always forget my standard shopping bags and I feel that the “bags for life” just replace one thin and crap lump of plastic for an overly engineered one.
The plastic ones (here in the UK at least) also split and fall apart, they’re better than the “standard” ones but they don’t usually last that much longer.
Also I have a million of them because I always forget to bring them.
I have both opinions: certain canvas bags will last you a lifetime and even you can fix them if necessary.
Most stores sell you "bags for life" that aren't either recyclable (truly) nor meant to last a year of daily usage, probably because they are cheaping out on the materials and production.
So we still end with a pile of garbage.
However, I am against single-use anything and would say that promoting truly lasting bags should be a priority over trying to figure out a solution for a single facet of a large issue.
I feel like the thicker 'bags for life' are a bit of a false economy. I could be remembering wrong but with those, you need to use them something like either 12 or 20 times for them to work out as being less harmful than the old disposable plastic bags.
I try to avoid using them where possible but where I can, but when I have, I can't say I've been able to use them more than 5 or 6 times on average.
