Product Insights
The I.FIV5 Mesh Racerback Sports Bra delivers sustainable features like REPREVE recycled polyester and Polygiene odor control at a competitive price, offering medium support suitable for gym sessions but insufficient for running or HIIT. The primary tradeoff is the non-adjustable straps, which are too short for longer torsos, causing shoulder discomfort and limiting bounce control to medium-impact activities, while the top band may curl after washing, affecting fit under fitted shirts.

Good purchase medium support sports bra. Maybe fits a little small love the colour.
Bon top très élastique
La bande élastique est de bonne qualité. Le dos respire bien. Le tissu blanc est toutefois mince et on voit les pads au travers.
Perfect fit
Good support and comfortable
Great fit, excellent material,good design
Love the mesh back on this. Lightweight and breathable but still provides support. I have big shoulders and sensitive traps. This bra fits perfectly, I can wear it all day comfortably . I bought multiples.
Short straps
The color ( baby blue ) was very nice, the fit around the torso was perfect, the fit and support of the cups was true to size, but the straps were too short for me and they are not adjustable, which means that it didn't take too long before the weight on my shoulders became uncomfortable and felt like it was pulling me down. I will wear this for short work-outs but definitely not longer than that. I am not returning only because I really love the color and I also bought the matching leggings and they fit great. I bought a size MED and I am always a size MED at Simons. I usually wear 34C.
