At K cup, the number of brands that build genuine high-impact support can be counted on one hand. Encapsulation is essential, the band must be very firm, and the cups deep and structured enough to hold their shape under real movement.
Matching the bra to the activity
High-impact styles — running, HIIT and jump-based training — use rigid encapsulated cups and a firm band; medium-impact styles suit the gym, cycling and reformer; wirefree and low-impact styles work for yoga, walking and rest days. At K cup the band does most of the work, so it should feel firm — if the straps are taking the load, the band is too loose.
