For high-impact workouts like spinning and HIIT
This medium-to-high-impact support bra is designed for demanding workouts that mix cardio and strength, such as spinning, cross-training, cardio dance, functional circuits, and running or HIIT. The mesh racerback and micro-perforated lining add breathability as you move, and Polygiene technology targets odour. In a review analysis, two reviewers reportedly found the support adequate for high-impact workouts.[1]
All-day comfort in a soft, cool-feeling bra
Wearing this bra from morning to night, when comfort is the priority. Its soft, stretch recycled nylon-blend microfibre is designed with a cool feel against the skin. Reviewers reportedly describe it as 'super confort' and 'très confortable', making comfort a standout in customer feedback.[1]
Product comparison
Compared within this brand.
| Mesh Racerback Shaping Bra Medium To High-Impact Support: Choose this if you want medium-to-high support for demanding cardio and strength workouts like spinning, cross-training, cardio dance, or functional circuits; review analysis also reports wearers confirming adequate support for running and HIIT and calling it very comfortable for all-day wear. It's built with a breathable mesh racerback, micro-perforated lining, and soft cups with removable foam padding. Note that according to a review analysis, it runs small, so consider sizing up if you're between sizes.[1] | Mesh Racerback Sports Bra Medium To High Support: Choose this if you want a bra for gym sessions and moderate activity such as spinning, cross-training, cardio dance, or functional circuits, with a breathable mesh racerback, soft cups with removable foam padding, Polygiene odor control, and thick ultra-stretch REPREVE fabric made from recycled plastic bottles. Per reviews, it runs true to size for most with fully wrapping cups and a secure band, though several reviewers advise treating it as medium support rather than relying on it for high-impact running or HIIT. Note the straps are fixed rather than adjustable, which can cause shoulder discomfort for longer torsos, and in white or pastel colors the thin fabric may reveal pad outlines under light tops.[2,3,4] | Padded-Strap Moulded Sports Bra High-Impact Support: Choose this if you want a wire-free bra with soft moulded cups for all-day wear, yoga, barre, or moderate gym training: reviewers report the cups keep their shape comfortably without underwire, and the padded straps are adjustable, removable, and multi-way, with a four-position hook closure and moisture-wicking, odour-controlling microfibre fabric. Note that despite the high-impact support designation, reviewers found bounce control lacking for running, HIIT, C+ cups, and larger busts due to a narrow chest band, so it works best for low- to medium-impact use. Sizing runs inconsistently across band and cup—some reviewers sized up while others found it too small or too large—and straps may slip in the standard setup unless worn crossed, which can add shoulder pressure.[5] |
