Racerback Sports Bra Medium To High-Impact Support
This medium-to-high impact racerback sports bra from the i.FiV5 performance collection features a round neckline, thin straps, and a racerback design for breathability.

Suitable for demanding cardio and strength workouts such as spinning, cross-training, and functional circuits, it includes soft cups with removable foam padding and a reflective logo.

Product Insights
The I.FIV5 Racerback Sports Bra Medium To High-Impact Support at 19.99 CAD is a pull-on, all-day-comfort training bra whose support holds for yoga, tennis and moderate gym work rather than running or HIIT; its wide underbust band sits non-restrictive even all day, the racerback cut and micro-perforated lining provide ventilation without a mesh back, and the 90% polyester/10% spandex lining with REPREVE recycled microfiber from six bottles wicks moisture inherently while Polygiene allows four to five wears before odor sets in and overnight air-drying clears it, with REPREVE yarn cutting carbon emissions 27-41% versus conventional polyester. The core tradeoff is sizing and adjustability: generic XS to XL ignores cup size, thin non-adjustable racerback straps suit smaller cups such as 34C but load larger cups such as 38C, and the pull-on design has no hook, zip or adjustable band even though it comes off easily when sweaty; loose foam cup pads shift during activity and washing, damp storage in a gym bag turns pungent within two runs, and dry fabric picks up cooking and smoke odors. It is otherwise valued as a single 19.99 CAD price across XS to XL and four colourways in 19 combinations, with White stopping at LARGE, sitting flush under open-back and racerback tank tops and moving from workouts straight into errands and lounging.
Verified claims
- Support
- Designed for medium-to-high-impact training such as spinning, cross-training, cardio dance and functional circuits; not enough support for high-impact running, HIIT, or D-cup support.
- Sizing
- Generic XS to XL sizing ignores cup size; thin straps load larger cups.
- Closure
- Pull-on, no hook or zip; easy off when sweaty, but no adjustable band.
- All-day comfort
- Buyers report a soft, non-restrictive band and plush fabric for all-day wear
- Cup padding
- Buyers report the loose foam cup pads shift during activity and washing and need repositioning by hand.
- Band fit
- Buyers report the wide underbust band sits non-restrictive rather than binding, even all day.
- Ventilation
- Ventilation comes from the racerback cut and a micro-perforated lining, not a mesh back.
- Moisture wicking
- REPREVE polyester's moisture wicking is inherent to the polymer and does not wash out.
- Odor control
- Polygiene buys roughly four to five wears between washes when the bra is aired between sessions, before odor sets in.
- Damp storage
- Left damp and crumpled in a gym bag, it turns pungent within two runs.
- Environmental odor
- Polygiene suppresses sweat-and-bacteria odor but does not capture cooking, smoke, or other ambient odors that polyester absorbs.
- Fabric technology
- 90% polyester/10% spandex lining with REPREVE recycled polyester microfiber from 6 bottles.
- Fiber performance
- REPREVE is a branded recycled performance fiber with durability, moisture-wicking, and stretch matching or exceeding conventional polyester.
- Value
- Black, Brown and Emerald/Kelly Green span X-SMALL through X-LARGE; White stops at LARGE. Every colour-size combination lists at the same price and is in stock.
- Layering
- The racerback cut sits flush under open-back and racerback tank tops
- Recycled content
- The main body is 83% REPREVE recycled polyester and 17% spandex, spun from six recycled plastic bottles; all of the polyester in the body is recycled REPREVE with no virgin polyester listed.
- Odor-control technology
- Polygiene is a permanent silver-salt treatment embedded at the fiber level, so it does not wash out and keeps controlling odor-causing bacteria for the life of the garment.
- Moisture management
- The micro-perforated lining and racerback vent heat and water vapour, while the hydrophobic polyester carries liquid sweat off the skin; the perforations are not themselves a wicking feature.

For yoga, tennis, and moderate gym workouts
According to customer reviews, this racerback bra holds in place during low-to-moderate impact sports like yoga, tennis, and weight training without excessive compression. Reviewers note it's not enough for high-impact running. The racerback design is intended to add breathability while you move, and its design makes it easier to take off when damp after sweaty sessions.[1,2]
Yoga, tennis, and moderate gym workouts — with a caveat on high-impact support
This racerback bra works as a training option for activities like yoga, tennis, and moderate gym sessions, where customers report the hold is sufficient. Though it is marketed for extra support in high-impact activities, customer reviews report the compression falls short for high-impact running or HIIT, so joggers may not get the bounce control they expect. Shoppers looking for a bra for lower-impact and moderate training may find it a fit, while those focused on running may want to weigh those reports.[1,3]
All-day comfort from workout to errands
Reviewers report wearing this I.FIV5 racerback sports bra throughout the day, from workouts to errands and lounging, without irritation. Its soft, non-restrictive band and plush fabric are credited with keeping it comfortable for daily all-day wear.[1]
Workout bra with removable padding that may need repositioning
This medium-to-high-impact racerback sports bra has thin, removable cup padding, which reviewers say can shift out of place during activity or in the wash. Some customers find the frequent readjusting frustrating, while others simply reposition the inserts and move on. It's a fit to consider if you don't mind occasionally straightening your padding — and possibly less so if you want set-and-forget padding.[1]
A base layer for open-back and racerback tops
Per customer feedback, this sports bra's racerback cut stays hidden under open-back styles, so it can work as a base layer under tank or racerback tops. That makes it a versatile option when you want support without visible straps or bands at the back.[1]
Product comparison
Compared within this brand.
| Racerback Sports Bra Medium To High-Impact Support: Choose this if your workouts are low-to-moderate impact — reviewers say it holds in place for yoga, tennis, and weight training without excessive compression, and its soft, non-restrictive band and plush fabric make it comfortable from workouts to errands. The racerback back cut also stays invisible under open-back tops, making it a versatile base layer. Note that despite the medium-to-high-impact labeling, some customers found it lacks compression and bounce control for high-impact running or HIIT, and the removable cup padding can shift during wear or washing.[1] | Mesh Racerback Sports Bra Medium To High Support: Choose this if you want a breathable bra for gym sessions, spinning, cross-training, and other cardio-and-strength workouts — reviewers found its support sufficient for moderate activity and its mesh back and moisture-wicking fabric comfortable in heat. It's made from ultra-stretch REPREVE® recycled polyester with removable foam padding, odor-controlling Polygiene® treatment, a secure wide underband, and fits true to size for most. Note that despite its medium-to-high-support billing, many reviewers say it lacks the bounce control for high-impact running, and the fixed straps can dig in or cause shoulder fatigue if you're tall or have a long torso.[2,3,4] | Multi-Strap Sports Bra Medium To High-Impact Support: Choose this if you want a medium to high-impact, pull-on sports bra for demanding cardio and strength workouts like spinning, HIIT, and cross-training — customers report its compression-level support and wide band keep everything in place without digging in. Reviewers also say it fits true to size, feels soft, and its opaque, stylish cut can even double as a swim top. Note that the pull-on design can be hard to peel off when sweaty or with limited shoulder mobility, and the removable cup pads may shift during wear and washing.[5] |

Sports bra review
Performs really well, good support and comfortable. Only negative is the “ floating” cup padding which tends to move around a bit. I wish this was attached inside.

Very comfortable and good support for smallish breasts.
Comfortable and supportive
One of the more comfortable sports bras I've worn. The padding is easy to move around inside the bra and the chest band isn't restrictive.
Perfect fit

Good fit, great price
This sports bra is comfortable and holds everything in place. It washes well too.
Mesh?
I thought the back of this bra was going to be mesh and breathable instead it has mesh lining. I’m extra wide around the rib cage and this bra didn’t dig into my ribs. Soft fabric. I bought both large and extra large to try on went with the large. Wear for tennis

Can actually get it off after a tough workout
This is the sports bra I’ve been waiting for! It’s so comfortable and holds everything in place. And the best part is that I can actually get it off after a tough workout!

Confortable et parfait pour porter sous une camisole à dos nageur, je recommande !
Très bien!
Je l’aime beaucoup, très confortable mais je ne le porterais pas pour de la course pas assez de soutien
