Product Insights
The I.FIV5 Racerback Sports Bra (39 CAD, in stock) blends medium-to-high impact support with deep sustainability: its four-way stretch, snap-back fabric resists bagging; micro-perforated lining wicks moisture for rapid drying; and 90% REPREVE recycled polyester (from 4 plastic bottles) cuts GHG emissions 42% versus virgin. Polygiene silver-chloride treatment blocks odor for the bra's lifetime, allowing fewer washes that reduce environmental impact by one third. However, this eco-engineering demands disciplined care—removable pads (optimized for A–D, smaller busts) must be taken out before each wash, fabric softener must be avoided to preserve wicking and elastic recovery, and air-drying flat is mandatory to maintain support. Sizing fits like Lululemon size 6 in S–M, with XS–XL offering no band/cup distinction.
Verified claims
- Sizing
- S–M size fits like Lululemon size 6; sizes XS–XL without band/cup.
- Cup volume
- Removable pads fit A–D cups but are optimized for smaller busts.
- Moisture management
- Moisture moves through micro-perforated lining for rapid drying without cling.
- Stretch and recovery
- Four-way stretch and snap-back; resists bagging and sagging.
- Recycled content
- Mesh: 90% recycled REPREVE polyester, 10% spandex; from 4 plastic bottles per bra.
- Environmental impact
- REPREVE recycled polyester matches virgin performance with 42% lower emissions.
- Sustainability
- Polygiene treatment reduces wash frequency, cutting environmental impact a third.
- Odor control
- Blocks odor at the source with silver ions; lasts the garment's lifetime.
- Skin safety
- Silver particles cannot penetrate skin; treatment is Medical Class 1 certified.
- Care
- Wash less often and air out; skipping washes cuts environmental impact by one third.
- Silver source
- Active silver is 100% recycled; treatment is certified bluesign and Oeko-Tex.
- Wash reduction
- Washing half as often cuts impact 33% and Polygiene lasts lifetime.
- Overall eco footprint
- REPREVE fabric cuts GHG 42% and water 67% vs virgin; plus Polygiene wash reduction.
- Pad removal
- Removable foam pads must be removed before every wash to prevent permanent deformation and mildew.
- Moisture wicking
- Fabric softener clogs the micro-perforated lining and REPREVE fibers, blocking sweat wicking.
- Support
- Fabric softener coats spandex, reducing elastic recovery and gradually loosening support.
- Wash cycle
- Remove pads, machine wash cold on delicate in a mesh bag, no fabric softener.
- Drying
- Air-dry flat; machine drying or hanging by straps damages support.
- Odour treatment
- Polygiene silver-chloride treatment lasts the bra's entire lifetime.
- Washing
- Wash inside out in cold water in a mesh bag without fabric softener, and remove pads first.
- Wash less
- Polygiene blocks odor, enabling multiple wears between washes; air-dry flat for support.

Recommend - good support for high impact cardio and lovely soft fabric. Very comfortable.
Confortable
Confortable avec un soutien léger, ce qui me dérange ce sont les pads, car il ne reste pas en place. Vous devez toujours les remplacer lorsque vous la mettez et si vous faites beaucoup d’activités, ils bougeront durant la journée.
Maintien et confort
Pour pratiquer toutes activités comme le yoga, le Pilates, la musculation et même la randonnée, je peux compter sur le maintien parfait, sans l'inconfort de bretelles trop minces ou d'attaches dans le dos.

J'ai acheté la taille "Petit" et elle est parfaite pour moi. Ce top est très confortable et il permet de bouger avec aisance durant les séances d'entraînement!

Le soutien est fait large; je le porte surtout pour mes courses hivernales. En été, il sera un peu trop couvrant
Très beau et confortable.

Super comfy
I’ve got a few of these because I’m an odd size (38A) and Large fits perfectly. It’s fine even without the removable cup liners and comfy for everyday wear. Great find.

Bon soutien. Design simple et efficace portée plusieurs fois en randonné. Respire bien. Mettre les pads après le lavage plus difficile.

Comfortable et qualité
Tres jolie et confortable. Offre un beau support sans être trop serré/compressif. Belle qualit. C’est une deuxième version dans mon cas. J’ai acheté le même l’an dernier et il n’a pas étiré et le tissus est encore très beau après plus d’une 40aine de fois a passé dans la machine.
Parfait!
La brassière la plus confortable que j’aie portée. Excellent soutien
Good fit
Good fit. Enough support for jogging, but still too bouncy when I skip.
