These Mum Bums are made in an athletic fabric which is moisture wicking so you stay cool even when you aren’t.

These come in 2 variations, regular and wide waistband.

This is a firmer fitting fabric than our regular Mum Bums.

These are custom made and non returnable, so please check size guide carefully before ordering. Measure across your hips, your widest part. If you fall in between sizes go smaller for a firmer fit or larger for a more relaxed fit.
