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 foam padding can help accommodate different cup volumes; the padded cups may work best for smaller to medium busts, though one reviewer reports a perfect fit for a 34DD.
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.
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.
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.
Wash cycle
Remove pads, machine wash cold on delicate in a mesh bag, inside out, and skip fabric softener.
Drying
Air-dry flat; machine drying, even on low heat, can relax the spandex and reduce the band's support.
Wash less
Polygiene blocks odor, enabling multiple wears between washes; air-dry flat for support.
Fit reference
A Poshmark reseller reports that a size S–M fits like a Lululemon size 6, giving shoppers a familiar benchmark for this bra's fit.
Support in practice
Buyers report good support for high-impact cardio and jogging, though one reviewer found it too bouncy for skipping.
Fabric feel
Buyers repeatedly describe the fabric as soft and comfortable.

Jessica D.

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.

Très beau et confortable.

Acheté en rouge. Super confortable. Le soutien est bas/moyen.

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.

Confortable!

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!

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

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

Parfait !

Couleur, fit, style et confort parfaits !

Super comfy

Paulie T.

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.
