My general feeling is that if something seems too cheap to be true, then the real costs are hidden elsewhere in the system. This is true with most products in our economic system, as very few companies build the environmental, climate, social, etc. impacts of their production into the costs of their products.
At the same time, I understand that everyone has a different economic situation and that some people can’t afford to spend very much money on backpacking gear. I am happy whenever the barriers to entry to backpacking are lowered, so that more people and communities can enjoy the places I love if they so desire. My hope is that in the future we can make further progress boosting wages in addition to accounting for the real costs of products, so that even if things get more expensive, the cost of living a healthy and nourishing life goes down.
Still, looking at these very cheap down products, I can’t help but think of the (very likely terrible) conditions that the birds and workers are in. There’s a reason that down products from responsible cottage companies are more expensive, as it costs much more to ensure that your down is ethically sourced and that your workers are receiving a living wage in safe conditions. Of course, I have no evidence that the maker of these bags is using live-force-plucked down or sweatshop/slave/child labor, but if it doesn’t advertise its production method, it seems too cheap to be true, and it’s coming from China, I think you need to assume the worst.
