Our advice
Compare the length of your dreadlocks to the sizing chart.
You can also make a loose bun with your dreadlocks to estimate the depth of the crown you need, or even compare with another hat you already have.
Sizes are given for average hair thickness: between 50 and 60 dreadlocks that are less than 1cm in diameter (0,40").
If you have rather thick, or very numerous, or even freeform dreadlocks, take the size above.
If, on the contrary, they are thin and/or few in number, aim for the size below.
