Fits well and does what it should
Well thought out product!.
The My Size brand is great for sizing, allowing you to adjust in small increments to get the right fit.
They have a useful measurement guide as well to provide a size, easy to understand.
If you're near the upper end of the scale for a certain size then I would suggest giving the size up from the recommendation a go, I've found while I technically just fit into the scale for 57mm it's still a bit too small but still give the recommended size a go first.
