I.FIV5
Mesh Racerback Sports Bra Medium To High Support
The Mesh Racerback Sports Bra is a women's performance bra designed for medium-to-high support during high-impact activities such as running and training. It features a scoop neckline, thin straps, and a breathable mesh racerback, constructed from ultra-stretch REPREVE polyester microfibre made from recycled plastic bottles, with a micro-perforated lining. The bra includes Polygiene odour-control technology, soft removable foam padding, a wide elastic underband, a reflective i.FiV5 logo, and a semi-sheer mesh back panel for ventilation.

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.
Verified claims
- Support level
- Buyers confirm medium support—good for gym, insufficient for running/HIIT.
- Value
- At $29.95, includes Polygiene and REPREVE features not typical at this price.
- Fit
- Non-adjustable straps are too short for longer torsos, causing shoulder discomfort.
- Activity suitability
- Non-adjustable straps limit bounce control, favoring medium-impact workouts.
- Strap length
- Straps are short for long torsos; sizing up helps.
- Color visibility
- Black option avoids sheerness; lighter colors may show pad outlines under light tops.
- Sheerness
- White and pastel colors reveal padding outlines; black masks them.
- Top band curling
- Buyers report top band curls outward after washing, visible under fitted shirts.
- Breathability
- Mesh back and micro-perforated lining keep you cool during intense workouts.
- Price comparison
- At $29.95 CAD, undercuts Nike and Lululemon by $20–48 with Polygiene and REPREVE.
- Strap adjustability
- Fixed straps keep price under $30; adjustability requires $50+ bra.
- Sustainability
- REPREVE polyester is traceable via FiberPrint and U-TRUST at $29.95.
- Ventilation
- Open mesh back and micro-perforated lining vent heat and sweat vapor during intense exercise.
- Moisture wicking
- Recycled polyester wicks identically to virgin polyester.
- Odor control
- Polygiene treatment eliminates odor and prevents bacteria growth.
- Traceability
- REPREVE fiber carries Unifi's FiberPrint tracer for auditable recycled content.
- Environmental impact
- Each bra repurposes 3 plastic bottles and reduces greenhouse gas emissions 42% vs virgin polyester.
- Environmental footprint
- REPREVE fabric reduces GHG 42%, water 67%, fossil fuels 66% over virgin polyester.
- Recycled content
- Bra's REPREVE fiber from 3 recycled bottles is traceable and U-TRUST certified.
- Performance parity
- REPREVE moisture regain same as virgin polyester (0.4%), so performance unchanged.
- Care instructions
- Wash only when necessary, no fabric softener, low detergent, machine wash any temp, air dry.

Deep Research
How the REPREVE fabric performs
- Every strand embedds Unifi’s FiberPrint® tracer, enabling independent labs to confirm the fabric's 3-bottle recycled content, and the U-TRUST® platform certifies the claim — turning the bra's sustainability story from a generic 'eco' tag into an audited, bottle-to-fabric chain that gives the buyer verifiable confidence.
- Repreve’s 2023 peer-reviewed LCA shows a 42% cut in greenhouse gas emissions and a two-thirds reduction in freshwater and fossil fuel use compared to virgin filament, so choosing this bra over a conventional-polyester equivalent directly lowers the garment's upstream resource burden by measurable amounts.
- REPREVE’s 0.4% moisture regain (ASTM D1909) matches virgin polyester exactly, so the fiber itself wicks and dries no differently — in this bra, sweat management is delivered by the open mesh racerback and micro-perforated lining, not by an exotic fiber chemistry.
Breathability of the mesh racerback design
- Because this bra is explicitly rated for high‑impact activities like spinning and cross‑training, its ventilation is engineered for the elevated metabolic heat of intense intervals — unlike a generic medium‑support bra, the open back and perforated liner are there to prevent the heat buildup that can make a thick, supportive bra a performance limiter.
- The bra layers an open mesh racerback over a micro-perforated lining, so hot air escapes through the back while sweat vapor passes through the liner instead of condensing — tackling trapped radiant heat and sweat‑soaked fabric cling, the two main sources of overheating in high‑support sports bras.
Value compared to similar sports bras
- The I.FIV5's CAD $29.95 sale price sits well below the $30–52 USD range (~$40–68 CAD) that entry-level brand-name medium-to-high support bras like the Nike Swoosh command, even at the lowest retail price point.
- Unlike generic recycled-polyester bras that omit the yarn source, the I.FIV5 explicitly uses REPREVE® certified fiber made from 3 recycled plastic bottles, giving eco-conscious buyers a verifiable sustainability claim at a price where certification is often sacrificed to hit a lower MSRP.
- Polygiene® permanent odor control is an uncommon inclusion at the CAD $29.95 price point, where competitors like the All In Motion High Support Bra ($30 USD) and the Running Girl High Impact Bra ($28.99 USD) rely on moisture-wicking alone—making the I.FIV5 a standout for buyers who want extra freshness between washes without upgrading to a $50+ bra.
- Listed for demanding cardio-strength hybrids like spinning, cross-training, and functional circuits, the I.FIV5 provides medium-to-high support at CAD $29.95—a category where the next step up in a major brand often crosses the $50 CAD threshold and adds features like adjustable straps that this bra foregoes for a cleaner, lower-cost design.
- As a Simons-exclusive PERFORMANCE piece designed in Canada, the I.FIV5 skips the traditional wholesale-to-retail markup chain, allowing it to pack REPREVE, Polygiene, and a reflective logo into a sub-$30 CAD bra—features that, in globally marketed brands, would push the price closer to $55–70 CAD.
Environmental benefits of the recycled fabric
- The same LCA shows REPREVE lowers freshwater consumption by 67% and water scarcity by 76% versus virgin polyester, so choosing this bra significantly reduces the water footprint associated with its primary material.
- Unifi's 2026 life cycle analysis found that REPREVE recycled polyester cuts greenhouse gas emissions by 42% compared to virgin filament polyester, meaning the carbon footprint of this bra's fabric is less than half that of a conventional polyester bra.
- REPREVE has repurposed over 35 billion water bottles into fiber since its inception, diverting them from landfills and oceans — purchasing this bra, which itself uses three bottles, supports a system that reprocesses waste at a massive, measurable scale.
- REPREVE production yields a 66% drop in fossil fuel depletion and abiotic resource use, directly reducing the demand for petroleum-derived raw materials compared to virgin polyester.

Colour is beautiful
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.

Q&A
1 answered- Can the Polygiene odor control technology withstand regular machine washing, and how should the bra be washed to maintain its properties?
- Yes, the Polygiene® odor control technology in this bra withstands regular machine washing when done properly. Wash only when necessary, use low amounts of detergent, and avoid fabric softeners (they feed odor-causing bacteria) [3]. Machine washing at any temperature is fine, but air drying is recommended to preserve the fabric and the technology [3].
