Asics Women's Run Brief (£13)
Kerry says: Being a fella I've not tried these but RW's trusted cadre of female gear testers report that they're something of an oddity in the sports brief market – in that they actually work. They don't bobble, rub, ride up, itch or any of the other things that many running briefs do. The classic cut provides a full range of motion, they're stretchy, supportive, wicking, and can be worn either with webbed or plain shorts. In fact, I'd say they're something of a bare necessity (badum tsh!).
