Are weighted vests good for women?

Hello! How are you all today?

So, basically, I have been wondering to purchase a weighted vest. However, I want to get my research in and fully contemplate before investing, as they are not cheap. Recently, I have been looking into increasing my endurance, speed, and overall strength. However, the one thing I don't want to do is get bulky, which is why I was kind of hesitant at strength training at first, but I am now doing FBStrong! (BTW, i is an AMAZING program!)

If anybody has a weighted vest or an opinion on the weighted vest, then it would be highly appreciated. Will it make me bulky? Is it useful for gaining strength and endurance?
