Product Insights
The Ultra-Soft Jersey Short from I.FIV5 delivers premium technical features—Polygiene, recycled polyester, zippered and hand pockets—typically found on shorts costing $68–$119, yet priced at $39. Its single-jersey knit fabric, crafted from recycled polyester identical to virgin material, provides natural drape and breathability without mesh panels, avoiding stiffness and bunching. Designed in Canada under Simons' 180-year heritage, the short offers a true-to-size relaxed athletic cut (sizing down yields a tailored look) and a rear zippered pocket. To maintain performance, avoid fabric softener, use gentle detergent, wash in a mesh bag only when needed, and add a white vinegar rinse every five washes.

Deep Research
Washing and care for long-lasting performance
- Washing the shorts in a mesh laundry bag shields the soft jersey surface from abrasion against zippers, hardware, and rough fabrics, which is the leading cause of pilling and snagging on recycled polyester activewear.
- Storing the shorts folded rather than hung on a hanger prevents the recycled polyester from gradually stretching under its own weight, preserving the waistband and hem's original drape even when stored for weeks.
- Fabric softeners deposit a waxy film that clogs recycled polyester's moisture-wicking pores and provide nutrients for odor-causing bacteria, directly neutralizing the Polygiene antimicrobial treatment — skipping softener is the single most impactful habit for keeping the shorts performing and smelling fresh.
- Polygiene's own care guidance states 'Only wash it when absolutely necessary' — because fewer washes reduce mechanical agitation on the fibers and preserve the antimicrobial finish, meaning these shorts stay fresh with less frequent laundering than untreated activewear.
- Using a gentle liquid detergent at half the usual dose prevents the buildup of soap film that traps odor-causing bacteria and dulls the jersey's hand feel, while avoiding powdered detergents that can be abrasive to the fine knit.
- Adding half a cup of white vinegar to the rinse cycle every 5–6 washes strips off detergent residue and body oils without coating the fibers, restoring breathability and maintaining the ultra-soft, non-coating feel of the jersey.
How these shorts compare to similar-priced options
- A rear zip pocket—frequently highlighted as a key feature on workout shorts in the $68-$100 range, like the Ten Thousand Interval or Lululemon License to Train—is included here at 39 CAD, providing secure storage that many budget shorts omit.
- Made from a recycled polyester blend, these shorts echo the eco-conscious material messaging of premium brands like Vuori (whose Kore Short runs $78 USD) while sitting at the budget end of the activewear market, making sustainable materials accessible at a no-upcharge price.
- As an I.FIV5 exclusive designed in Canada by Simons, these shorts carry a curated design legitimacy that generic budget shorts lack, borrowing from the retailer's 180-year heritage to signal a level of intentionality in fit and materials.
- I.FIV5 applies the same Polygiene odor control and recycled polyester fabric to its $59 Minimalist Stretch Short, confirming that core technical features aren't reserved for higher-priced pieces but are standard across the brand's line—so the 39 CAD entry point doesn't sacrifice this tech.
- Polygiene antimicrobial odor control appears on shorts like the La Sportiva Comp ($85) and FORLOH SolAir ($119), yet it's built into this 39 CAD short, giving buyers a technology that typically commands a $40+ premium at a fraction of the cost.
The ultra-soft stretch jersey fabric explained
- Single jersey drapes naturally against the body and moves with the wearer, so the shorts avoid the stiffness and bunching of woven workout bottoms — you get the comfort of a T-shirt knit in a training short.
- Because the shorts are cut from single jersey knit rather than a woven, the yarn’s loop structure creates natural channels for air to pass through, keeping the shorts breathable without relying on mesh panels or perforations.
- Recycled PET shares the identical polyethylene terephthalate polymer backbone as virgin polyester, so the shorts dry quickly, resist wrinkles, and hold their shape after stretching just like conventional polyester activewear — but the feedstock was post-consumer bottles rather than petroleum.

Q&A
1 answered- How does the sizing compare to typical athletic shorts? Are they true to size, or do they run slim or relaxed?
- These shorts are designed with a stretch jersey fabric and an adjustable drawcord waist, so they generally fit true to size with a relaxed, athletic cut. If you prefer a more tailored look, you can size down, but most wearers find their usual size comfortable.
