Yeah, Amazon search results are often infuriating. Most searches are flooded with similar items that need better filters and some notes on product differentiation. Amazon feels like a bazaar set up inside a Walmart where everyone is yelling at you to buy from them and you don't really know what you're going to get. I know it's a hard problem, but I can often look at the results and imagine some easy UX improvements. Maybe they have higher priorities than helping me buy insulated pants.
