Just to have you even more comfortable 404s doesn't hurt your site

Do people really search for red Boston Bruins hats? Or do they search for Boston Bruins hats? Frankly, as a consumer, I'd find it annoying to have to sort through that many more pages if you implemented A. But since color may be important, I'd make it a filter as AWC suggests. I'm not familiar with Shopify, so don't know if it's built in. If not, I'd build it. I'd address your last usability concern the same way - i.e., customize your software.

Hi Jackson, It would be better if there was just one uniform URL for the product but for some websites that have thousands of products it is just too big a development cost so they get around it by using the canonical tag, this is perfectly fine and there aren't any issues from an SEO perspective. So if you can, I'd change it so that there is one URL per product but there is nothing wrong with using the canonical tag
