I bought the wine/navy WB size for my light 17.1 Clyde boy and it first him with room to spare. I love the darker hardware on the halter, how light it is and how soft on my guy's face. The lead rope isn't the best quality - it's short, light and already pilling but it does the job. There are lots of great colours to choose from - something lacking in items that fit my boy. I'll get another as soon as I can!
