Product Insights
The Ultra-Soft Sleeveless T-Shirt from I.FIV5 is a Simons-exclusive, yoga-inspired tank top made from 92% recycled polyester and 8% elastane, offering a soft, matte, quick-drying fabric with permanent Polygiene® odor control that saves water and energy with less frequent washing. Its relaxed fit supports movement but sizing down restricts range, and care requires cold washing and low heat drying to maintain durability and shape.

Deep Research
The I.FIV5 brand and its place in activewear
- As a Simons exclusive private label, I.FIV5 is developed and retailed solely through the Canadian department store, meaning its design direction aligns with Simons' contemporary curation rather than a standalone athletic brand — for buyers, that translates to a tank not found at generic sports chains, carrying a subtly distinct fit and fabric selection informed by the retailer's in-house design team.
- The tank's built-in Polygiene® treatment uses recycled silver salt to actively eliminate odor-causing bacteria, so the fabric resists stale smells even after intense workouts, making it practical for multi-day wear or back-to-back gym sessions without immediate laundering.
- Drawing on the drape and ease of yogi clothing, the tank boasts a relaxed, amplified silhouette that prioritizes freedom of movement and a fluid profile, making it a natural choice for low-impact studio sessions and casual wear rather than high-compression training.
- The primary fabric is 92% recycled polyester sourced from plastic bottles, lowering the garment's raw-material impact without sacrificing the quick-dry resilience needed for active wear; the 8% elastane ensures a full range of motion.
How Polygiene technology controls odor
- The silver ions in Polygiene are more than 100 times larger than nanosilver particles, so they cannot penetrate the skin barrier — this directly addresses safety concerns about silver-based antimicrobials migrating into the body while maintaining full antimicrobial efficacy.
- Polygiene-treated fabrics hold Medical Class 1 approval in Europe — the same category as bandages for direct contact with open wounds — confirming the treatment is safe for prolonged skin contact, non-irritating, and does not affect the skin's natural bacterial flora, so you can wear it with confidence even on sensitive skin.
- The silver ions disrupt odor-causing bacteria by binding to their cell membrane proteins and blocking the respiratory system, which prevents microbes like Corynebacterium from converting sweat proteins into the volatile fatty acids responsible for post-workout stink — this is microbial control, not fragrance masking.
- An independent LCA on a Polygiene-treated t-shirt showed that skipping every other wash saves 51 kWh of energy and 3,800 liters of water per year — so wearing this tank top multiple times between washes has a tangible environmental benefit beyond just convenience.
- Polygiene embeds silver chloride directly into the fabric fibers at the finishing stage, not as a surface coating, so the antimicrobial effect remains fully active through the entire lifespan of the tank top — even after years of washing, it won't wash out or stop working, preventing the embedded odors that plague untreated synthetic activewear.
- The silver chloride in Polygiene is sourced from 100% recycled industrial silver (photographic and industrial applications) — the silver from a single ring is enough to treat roughly 5,000 garments, minimizing the fresh-mining burden and making the anti-odor treatment resource-efficient.
What makes recycled polyester feel soft
- At 8% elastane, the blend does more than provide four-way stretch: it lowers the fabric's resistance to body contours, so the wearer experiences a soft, flexible caress rather than the plasticky friction of unblended recycled polyester.
- Thanks to identical polymer chemistry and fine filament spinning, recycled polyester can match — and in some engineered finishes exceed — the softness of virgin polyester, so the sustainability story never comes at the cost of next-to-skin comfort.

Q&A
3 answered- How does the relaxed fit compare to standard tank top sizing? Should I size down for a more fitted look?
- This top is designed with a relaxed fit inspired by yogi clothing, meaning it is intentionally roomy through the body and arms. If you prefer a more fitted look, we recommend sizing down. However, the fit is meant to allow ease of movement, so consider your activity before downsizing.
- What are the recommended washing instructions for this top, especially to maintain the Polygiene odor control technology?
- To maintain the Polygiene odor control technology, we recommend washing the top in cold water on a gentle cycle and avoiding bleach, fabric softeners, and high heat drying. Turn the garment inside out before washing and line dry or tumble dry on low. These steps help preserve the antimicrobial treatment and the fabric's elasticity.
- How does the recycled polyester blend hold up to repeated washing and stretching over time? Is the fabric prone to pilling or losing shape?
- The recycled polyester blend with 8% elastane is generally durable and holds its shape well with proper care. It is not prone to significant pilling, but as with any activewear fabric, following the care instructions (cold wash, low heat drying) will extend its lifespan. The blend is designed to withstand repeated stretching and washing without losing its softness or shape.
