Racerback Sports Bra Medium To High-Impact Support

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.

Washing and care to keep it lasting

• The foam cups must be removed before every wash and dried separately; left inside, they can bunch permanently, trap moisture in the bra’s micro-perforated layers, and become a breeding ground for mildew, which undercuts the garment’s anti-odor technology.
• Fabric softeners and dryer sheets are directly counterproductive — they deposit a film that not only clogs the bra’s moisture-wicking pores but also provides a nutrient source for odor-causing bacteria, effectively nullifying the Polygiene® stay-fresh benefit.
• A cold-water (30°C) delicate cycle, combined with a zippered mesh laundry bag, shields the ultra-stretch REPREVE® microfibre and micro-perforated lining from friction that causes pilling, while keeping the racerback straps from stretching out of shape and preventing heat damage to the spandex’s elasticity.
• Turning the bra inside out before washing places the sweat-saturated inner surface in direct contact with detergent, which reduces the bacterial load that can challenge the Polygiene® finish over time — particularly important for a high-impact bra worn during intense training sessions.
• Because the bra is treated with Polygiene® antimicrobial technology, it only requires infrequent washing — hanging it to air out after workouts reactivates the finish's bacteria-inhibiting function, which means less fiber degradation from machine cycles and a longer lifespan for the elastic and moisture-wicking properties.
• Skipping the machine dryer entirely is critical — even low heat can permanently relax the spandex and cause the band to lose its medium-to-high support, whereas air-drying the bra laid flat on a towel preserves the shape and compression without deforming the straps.

How Polygiene odour control holds up through sweat and washes

• The silver ions in the silver chloride salt block the bacteria that feed on sweat and produce odor, so the bra stays fresh not by absorbing smells but by preventing them from forming in the first place.
• The active silver in the treatment comes entirely from recycled industrial and photographic waste — the amount of silver in a single ring can treat about 5,000 garments — meaning the odor-fighting benefit adds almost no new mining pressure.
• Polygiene’s silver particles are over 100 times larger than nanosilver, cannot cross into the skin, and the treatment achieved European Medical Class 1 certification — the same rating as bandages that touch open wounds — so wearing this bra for long workouts poses no dermal risk.
• Polygiene is added at the finishing stage and becomes part of the textile itself — it does not wash out or degrade, so the bra retains anti-odor performance for its entire useful life, not just the first few washes.
• Polygiene’s own LifeCycle Assessment of a treated T-shirt found that skipping every other wash slashed total environmental impact by 33% — applying that logic to this bra, if you wash it half as often, you cut its water, energy, and carbon footprint by a third.
• The Polygiene chemistry itself is bluesign approved and Oeko-Tex Eco-Passport certified, meaning the anti-odor treatment meets strict standards for worker safety, consumer health, and low environmental impact throughout the manufacturing chain.

What REPREVE recycled fabric feels like and how it performs

• Because REPREVE is chemically identical to virgin polyester, its moisture regain sits at just 0.4% per ASTM D1909, meaning the fiber absorbs practically no sweat — instead, moisture moves via capillary action between the fibers and through the micro-perforations, so the bra stays lightweight and dries fast rather than clinging and chafing during high-output cardio.
• The REPREVE lining is engineered with micro-perforations — tiny, knit-in breathing holes that allow evaporating sweat to escape directly from the skin through the fabric rather than being trapped inside the bra, a feature that works synergistically with polyester’s inherent wicking to accelerate cooldown during interval training.
• Producing the REPREVE yarn for this bra generated 42% fewer greenhouse gases, used 67% less freshwater, and consumed 66% less fossil fuel compared to making virgin polyester from petroleum, according to Unifi’s 2023 lifecycle assessment — so the bra’s environmental cost is dramatically lower before it ever reaches your drawer, with no on-body performance sacrifice.
• The bra’s main body fabric is REPREVE, a 100% recycled polyester fiber from Unifi that has kept over 42 billion plastic bottles out of landfills since 2007 without sacrificing the performance properties of virgin polyester — it matches virgin PET for quick-drying, strength when blended with spandex, and long-term durability in activewear.
• By pairing REPREVE microfiber with 10% spandex, the bra achieves a stretch-and-recovery system where the recycled polyester provides structural stability and moisture transport while the elastane delivers four-way stretch and snap-back — the combination resists the bagging and sag common in sportswear that uses spandex as a sole stretch source, extending the bra’s wearable life through repeated high-impact sessions.
• In end-use sportswear like this bra, the difference between REPREVE and virgin polyester is invisible — both deliver the same lightweight hand, quick-dry behavior, and dimensional stability because the polymer is identical; the only meaningful divergence is the 42% smaller carbon footprint, making the choice a sustainability gain with no athletic compromise.
