Product Insights
The I.FIV5 Velvety Thin Crossed-Strap Support Tank uses hospital-grade recycled silver for permanent odor control, staying fresh for 20 hours of mixed gym use, and features a permanent peachskin finish on microfibre for velvety softness that won't wash out. However, it runs a full size small, the hem rides up during movement especially if too tight, and fabric may pill after a few gentle washes. Best for yoga, Pilates, and weightlifting, not for running or intense cardio, it offers low- to moderate-intensity support with pads that add coverage and shape but not lift. The tank doubles as a visible casual top, contains recycled nylon and recycled silver from e-waste, and holds bluesign, Oeko-Tex, and REACH certifications, reflecting its 184-year Quebec heritage.

Deep Research
How Polygiene keeps the tank fresh
- Polygiene was developed in 2006 to control bacterial contamination in hospital environments, which gives context to why the treatment is more than a cosmetic anti-odor rinse — it’s a medical-grade approach to microbial control that was later adapted for performance apparel.
- Applied during the finishing stage of manufacturing, Polygiene becomes an integral part of the fabric rather than a topical coating, so the odor protection lasts the lifetime of the tank — not washing out or wearing off after multiple laundry cycles.
- Polygiene's Bluesign approval signals that its manufacturing meets independent standards for consumer safety, low chemical impact, and responsible resource use, so the odor defense inside this tank doesn't come at the expense of environmental or health tradeoffs.
- Unlike some antimicrobial treatments that can disturb skin flora, Polygiene is engineered to remain active only within the textile and doesn't interfere with the body's natural bacteria — an important detail for a built-in-bra tank that sits against the chest for extended periods.
- The Polygiene StayFresh technology used in this tank is based on silver chloride recycled from electronic waste — a sustainable sourcing choice that makes the antimicrobial treatment both effective against odor-causing bacteria and lower-impact than virgin-mined silver alternatives.
- A GearJunkie reviewer wore a Polygiene-treated shirt for 20 hours over two weeks — including 3-hour runs, spinning, mountain biking, and weightlifting — then left it in a gym bag with dirty shoes; it never developed odor, testing the exact scenario of between-wash wear that this tank is designed for.
- Another GearJunkie writer wore a Polygiene-treated Patagonia hoody almost daily for three weeks — through backcountry trips, climbing, and daily life — without washing and still found no discernible funk, indicating the treatment can sustain heavy, continuous use far beyond typical expectations.
- An Outside Magazine tester wore a Polygiene-treated top for eight consecutive days of running, working, and sleeping, concluding the shirt smelled only as foul as a standard synthetic does after a single long run — a roughly 8:1 improvement in laundry deferral that directly translates to this tank's utility for multi-wear athletes.
The I.FIV5 brand: Simons' Canadian activewear line
- i.FiV5 is one of Simons' proprietary in-house lines, not a third-party brand — this vertical integration means the design team controls fit, fabric selection, and production details like the reflective logo and the crossed-back straps directly, rather than adapting a white-label template, which tends to yield more cohesive sizing and a distinctive look at the $49 price point.
- Simons, the house behind i.FiV5, was founded in 1840 as a dry goods store in Quebec City and is still privately held, giving the brand a 184-year legacy that began in hardware and textiles before evolving into a Canadian fashion authority — when you buy this tank, you're buying into a lineage that spans from 19th-century retail to contemporary private-label activewear designed in-house.
The velvety fabric: comfort and sustainability
- The peachskin finishing treatment inherently reduces pilling and snagging by removing loose microfibres, so the tank maintains its smooth surface through friction from gym bags, yoga mats, and repeated laundry cycles.
- The jersey is knit from microfibre — fibers finer than 1 denier — which amplifies the softness and gives the fabric a fluid drape that moves with the body during stretching and bending, a key benefit for a support tank worn in yoga and Pilates.
- The peachskin feel is the result of a mechanical brushing or sanding process that raises the surface fibers of the microfibre jersey, creating a permanent velvety nap that mimics the softness of a peach — unlike a chemical softener that can wash out, this physically altered fiber structure retains its plush hand over the garment's life.
How the micro-perforated lining enhances airflow
- The micro-perforations have sealed edges—a hallmark of laser-cut fabrication—that prevent fraying and unraveling, so the lining maintains its breathable structure through repeated wash cycles unlike mechanically punched holes that can enlarge over time.
- The perforations work in tandem with the recycled nylon microfibre: as the fabric wicks sweat, the holes accelerate evaporation, cutting dry-down time and preventing the clammy feel that can develop when a non-perforated lining traps moisture against the skin.
- The micro-perforated lining relies on tiny laser-cut holes—typically 0.3 to 1.2 mm in diameter and spaced 2–5 mm apart—that provide direct vapor escape routes rather than relying solely on the fabric’s wicking capacity, meaning sweat evaporates faster and the skin stays drier during yoga or gym sessions.
- Micro-perforations add virtually zero bulk or stiffness, so the lining remains a featherweight second skin that disappears under the velvety outer jersey, avoiding the extra seam lines and potential chafe points that come with traditional mesh panels.

Bon soutien et très confortable
Trop petit
j,ai fait venir small (petit) mais c’était comme un Xsmall (très petit)…. normalement je prends toujours Small, mais je l’ai gardé quand meme.
Ne tient pas sur les hanches
Le tissu est confortable. La camisole remonte toujours vers la taille ce qui rend le tout très inconfortable.
Belle coupe
Beau modèle, tissus doux, bon support, confortable. Il faut prendre une taille plus grand qu'à l'habitude. Faite très petite.
I like it!

Great description

Q&A
5 answered- How does the built-in bra sizing work? Is it based on standard bra band/cup sizes or generic S/M/L based on dress size?
- The built-in bra is sized by the tank's size (XS to XL), not by standard bra band/cup sizes. It features removable foam padding so you can adjust the fit and coverage as needed.
- What level of physical activity is this tank suitable for (e.g., yoga, running, weightlifting)?
- This tank is best suited for low to moderate intensity activities like yoga, Pilates, weightlifting, or casual gym sessions. The delicate straps and velvety material are not designed for high-impact exercises such as running or intense cardio.
- How does the fabric handle sweat and moisture during exercise—is it moisture-wicking or absorbent?
- The fabric is moisture-wicking, thanks to the breathable micro-perforated lining and quick-drying recycled nylon microfibre. It helps manage sweat, though it may not be as high-performance as dedicated polyester athletic wear.
- What are the recommended washing instructions to maintain the Polygiene odor control technology and prevent damage?
- To maintain the Polygiene odor control technology, machine wash in warm water with mild detergent, avoid bleach and fabric softeners, and tumble dry on low heat. Do not iron the pads.
- Do the removable foam pads tend to shift or bunch up during wear or after washing?
- Shifting or bunching of the removable foam pads can occur during washing, but this varies by individual. To prevent it, remove the pads before washing or place the tank in a lingerie bag. During wear, the crossed-back straps and snug fit help keep the pads in place.
