Gemm Non Wired Sports Bras

Underwire and hard exercise don't always get on — it shifts, it digs, and at a larger bust that's more than a minor annoyance mid-session. This is our full high-impact range built with no wire at all, so the support comes purely from the construction.

Individual cup encapsulation, a firm non-slip band, reinforced straps — that's what's doing the work here instead of a wire, and it controls movement at G cup and above just as well. Zip-front and pull-over are both in the range, so pick whichever's easier to deal with around a workout.

Running, HIIT, cycling — anything where bounce control genuinely matters, not the low-impact styles that get labelled "sports" and aren't. If you're between D and J and most sports bras have felt either flimsy or restrictive, this is the range built for that gap specifically.

Does non-wired hold up for high-impact training?

With proper encapsulation design, yes — structured cups, a firm band and reinforced straps take over the job the wire would normally do.

Sizes?

Up to 46 band, J cup, depending on the style.

Zip-front or pull-over?

Zip-front is easier on and off, especially post-workout or with limited shoulder mobility. Pull-over tends to give a closer, more compressive fit. Both are here.
