This is a classic hard-brush, medium-stiff with a little whippy-ness to it, so you can flick off sand and dust, but still tough enough to use on dirty legs. The plastic bristles work well and are easily cleaned. I am adult with a small hand and the size of these is great. They are also a bit lighter than a full size brush, which, again, makes flicking dirt/dust off easier. The fun colors are a bonus! This is my absolute go-to brush.
