Straight browband without any extra details for you who prioritize function over appearance.
You can choose to have either 2 or 4 ring knots on your browband. Browbands with 4 ring knots are meant for bridles with a throatlatch where the extra ring knot on each side sits inbetween the headstall and the throatlatch to keep them in place (see picture 3 for an example of a fully assembled bridle). If you want a browband for a rope halter or a bridle without a throatlatch you should preferably choose 2 ring knots instead.
Please check out the page Size guide
if you are unsure which size to choose.
