Anyway, this is small shop selling one or 2 different gloves. Main point of this shop is offer lover price compare with other shops, on similar gloves. Its not about something brand able, because most shops have same gloves just price are different, so this shop is not about brand. Question is when peoples typing work gloves in google witch domain would be better? Probably workgloves.com but gloves.com is one word with local domain end...
Again I will give another example. Imagine Amazon website with goodsforsale.com or alltypesofproducts.com
You are starting with maybe one or two products in a particular niche, but who knows you can broaden the niche and choice of products at a later age! So I will again suggest to go for a brandable name and concentrate on the content keywords when you want to rank in search engines.
