NipStyx

NipStyx is a running-focused brand creating reusable silicone nipple protection designed to help prevent chafing during training and races. Built by runners for runners, its self-adhesive nipple armour forms a flexible barrier between skin and clothing, aiming to reduce friction while remaining comfortable through sweat, rain, heat, and long distances. The product is made from medical-grade silicone, is moisture-wicking and waterproof, and is designed to sit discreetly under clothing and accommodate different body shapes.

Unlike tape, plasters, or creams, NipStyx is intended to stay in place without mid-run reapplication, sticky residue, or painful hair removal. No shaving or waxing is required. After use, the protectors can be rinsed with warm water, air-dried, and reused; the brand says they are typically reusable three times, with some customers reporting more uses.

NipStyx reports field testing by marathon runners, pace-team members, and athletes across Australia, the UK, and Asia, including use in marathons, ultras, and trail runs.
