Product Insights
A yoga bra for low-impact movement, merging sustainable recycled nylon with lifetime Polygiene odor control. Its crisscross straps prevent slipping while allowing full shoulder mobility, and the micro-perforated lining keeps you dry. However, support is limited to C–D cups for gentle yoga only, and the generic XS–XL sizing, along with required cold washing and flat drying, demands specific care to preserve performance and odor protection.
Verified claims
- Strap stability
- Crisscross straps resist slipping during yoga flows.
- Shoulder mobility

Deep Research
Cross-back strap design and freedom of movement
- The crisscross back naturally locks the straps in place against the torso, so they won't roll or slide off the shoulders during a vinyasa flow — a persistent annoyance with straight straps that can interrupt focus and comfort.
- Unlike straight straps that can pull or bind when you reach overhead, the thin cross straps allow full scapular movement — critical for yoga transitions like flowing from plank to upward dog or for poses that require a deep shoulder stretch.
Fabric feel and breathability during low-impact activities
- The interior lining's micro-perforations create a network of escape routes for warm air and sweat vapor, preventing moisture from pooling against the skin even while the outer face feels plush and velvety.
Care and longevity of recycled nylon fabric
- The bra's thin cross-back straps and delicate knit are vulnerable to machine snags that cause pilling and thread pulls; a fine-mesh laundry bag acts as a protective barrier against zippers and hooks, a practice linked anecdotally to multi-year durability in similar activewear.
- Fabric softeners coat the recycled nylon fibres with a waxy film that clogs the micro-perforated lining’s breathability and can smother the Polygiene treatment, leaving the bra feeling sticky instead of velvety — damage that is irreversible, making a half-dose of synthetic-specific detergent and an occasional vinegar rinse the safer maintenance path.
- Sweat and body oils chemically attack spandex, accelerating the loss of elastic recovery that gives the band its grip; washing the bra after every yoga or stretching session removes these oils before they can stiffen the elastane, helping the low-impact support remain consistent for the full life of the Polygiene treatment.
- Washing recycled nylon in cold water preserves the microfibre's velvety peachskin hand and prevents shrinkage; even a 40°C wash triggers elastane memory loss after 10–15 cycles, meaning the low-support band and cross-back straps can become permanently loose long before the fabric itself shows wear.
- Every 5–6 washes, adding half a cup of white vinegar to the rinse cycle strips away detergent residue and hard-water minerals that can compromise the microfibre’s peachskin feel, restoring the original velvety texture without interfering with the recycled nylon’s breathability or the Polygiene’s odor control.
- Leaving the removable foam cups in place during washing traps water and bacteria inside the pad pocket, which can compromise the Polygiene’s ability to prevent odor and causes permanent creasing that telegraphs through tops; removing them lets detergent reach every surface and extends the life of both the pads and the garment.
- Tumble dryers operate at 50–70°C even on low, enough to degrade the elastane and permanently stretch out the band and straps; air-drying the bra flat indoors avoids that heat and prevents the cross-back straps from elongating under the weight of wet fabric, preserving the shrunken, supportive silhouette.
Environmental benefits of recycled nylon
- Recycled nylon manufacturing uses up to 90% less water than starting from virgin petroleum-based nylon — a critical resource conservation point given the textile industry's heavy water footprint.
- Producing recycled nylon can generate up to 90% fewer CO₂ emissions than virgin nylon, so choosing a bra made from this fabric dramatically reduces the raw-material carbon footprint of your activewear wardrobe.
- A large share of recycled nylon is sourced from discarded fishing nets — an estimated 640,000 tons of fishing gear are abandoned in oceans each year — so wearing this bra helps repurpose that problematic waste stream into a functional, second-life textile.
- Recycled nylon retains high durability, flexibility, and abrasion resistance comparable to virgin nylon, so the peachskin feel and stretch of this bra do not trade off longevity for sustainability.
Polygiene odor control for low-impact wear
- An Outside Online editor wore a single Polygiene shirt for eight days of runs up to 6.7 miles, work, and sleep; only at day eight did the armpits smell slightly sour — comparable to a non-treated shirt after one long run — effectively delivering a full week of smell-free synthetic wear for anyone willing to spot-clean with air.
- In a 2014 GearJunkie stress test, a Polygiene-treated synthetic shirt worn for 20 hours over two weeks — including 3-hour runs, spinning, mountain biking, weightlifting, and then being stuffed into a gym bag alongside funky shoes — never developed any odor, showing that the treatment can survive the kind of abuse that makes untreated polyester reek in a single session.
- Polygiene’s active ingredient is silver chloride derived from recycled electronic components, a closed-loop antimicrobial that sidesteps the environmental and ethical issues of virgin silver mining — important for a garment that will be washed frequently and could otherwise leach harmful substances.
- The Polygiene treatment is Bluesign-approved for responsible manufacturing and Oeko-Tex Eco Passport certified for safe chemistry, and independent testing found it does not irritate skin or disturb its natural bacterial flora — meaning the anti-odor protection comes without chemical trade-offs against comfort or skin health.

Versatile, à apporter en vacances
Je la trouve douce et très confortable. En vacances je l’ai utilisée dans le bain tourbillon, au gym, sous une chemise en lin, pour chiller dans ma chambre. Compacte, parfaite, sèche rapidement. J’ai acheté médium pour 32C.
Really nice bra!
Im a 32DD so I usually size down or the band is not supportive enough but it feels tight at first. After a few wears, it stretches out to fit perfectly. The fabric is starting to pil already but it feels like great quality.
Q&A
3 answered- Does the sizing align with standard bra band/cup sizes, or is it based on generic S/M/L with specific chest measurements?
- Our sizing is based on generic X-SMALL through X-LARGE rather than standard bra band/cup sizes. We recommend referencing the size chart on our product page for specific chest measurements to find your best fit.
- How does the support level compare for cup sizes C and D? Is it sufficient for low-impact activities like yoga?
- This bra is designed for low-impact activities like yoga, stretching, and walking. While it offers gentle support, it may not provide sufficient structure for larger cup sizes C and D during more dynamic movements. For yoga, however, many find it comfortable for light practice.
- How long does the Polygiene odor control last? Is it effective for the lifetime of the garment, or does it diminish after many washes?
- Polygiene® technology is bonded into the fabric at the fiber level and is designed to last for the lifetime of the garment, effectively controlling odors wash after wash without diminishing.
