The Amazon Essentials jacket looks very similar to the Costco $30 (or was it $20?) jacket. I bought one at Costco a few years ago, thinking it's ok as a backup or just light jacket around the house. They are cut rather large, so fit is nothing like the athletic cut of the pricey competition. Material is pretty robust (heavy), and the insulation is pretty thin.
Still does the job. I keep one in my office for quick walks out in the cold, but for anything serious, I prefer a lighter more packable jacket with a hood. Yes, even on sale, those cost 3 to 4x as much as these.
If all you want is a warm layer under a shell, it'll work fine
