Minimalist Stretch Short Without Built-In Brief 5" Length
The i.FiV5 Minimalist Stretch Short is a 5-inch (13 cm) inseam athletic short without a built-in brief, constructed from lightweight, stretch recycled polyester. It is suitable for running and training, featuring Polygiene odor-control technology, an elastic waist with an adjustable inner drawstring, vertical slit front pockets, a hidden side-seam zip pocket, a simulated fly, mini side slits, and a heat-bonded hem. A reflective i.FiV5 logo enhances visibility, and the design originates from Simons' i.FiV5 line designed in Canada.

Product Insights
The Minimalist Stretch Short by I.FIV5 is an unlined, Polygiene-treated recycled polyester short that stays odor-free for weeks, wicks moisture (absorbing only 0.4%), and maximizes airflow and mobility for yoga and dynamic warm-ups. Its linerless construction eliminates chafe-causing seams and bunching over tights, while the elastic waistband with drawstring and side-slits ensure secure, non-binding movement. The main tradeoff: no built-in liner requires firm cinching, and the fake fly reduces hardware for a lightweight feel but may not suit all preferences.
Verified claims
- Odor control
- Polygiene-treated polyester stayed odor-free through a three-week backcountry trial and showed only mild sourness after eight days of continuous wear, far less than untreated polyester after a single long run.
- Skin safety
- Polygiene is tested non-irritating and microbiome-friendly, safe for sensitive skin.
- Mobility
- Allows full range of motion for yoga and dynamic warm-ups.
- Chafing prevention
- No liner seams to chafe, and you can wear underwear you trust.
- Ventilation
- More airflow than lined shorts and layers over tights without bunching.
- Waistband fit
- Fits securely with elastic waistband and drawstring, adaptable to body shape.
- Movement fit details
- Bonded hem, side slits, and fake fly reduce chafing and restriction; flush zip pocket prevents swing.
- Unlined construction
- No liner prevents chafe, boosts airflow and mobility, and stays dry; requires firm cinching.
- Secure hold and stretch
- Stretch fabric and drawstring waist deliver secure, non-binding hold for full-range motion.
- Moisture wicking
- 90% recycled polyester/10% spandex fabric absorbs only 0.4% moisture, staying dry during exercise.
- Breathability
- Unlined single-layer shell maximizes airflow for cooling during workouts and layering.
- Environmental impact
- Recycled polyester production reduces energy by 45–85% and CO2 by 30–60% vs virgin.
- Pocket stability
- Side-seam zip pocket sits high on hip near center of mass, avoiding bounce or sag during runs.
- Linerless design
- No built-in liner prevents bunching and sweat traps when worn over tights.
- Pocket layering
- Side-seam zippered pocket lies flush and accessible when worn over tights.
- Fake fly
- The trompe-l'oeil fly eliminates zipper hardware for a lightweight, barely-there feel.
- Waistband security
- Elastic waist with drawstring stays put during squats and lunges.
- Odor control after washing
- Polygiene odor control is designed to last the lifetime of the garment, and many users report it remains effective after multiple washes; for this specific short there is no published test data beyond 20 washes.
- Quick drying
- Because recycled polyester absorbs only 0.4% moisture, sweat is pushed to the surface and evaporates, so the shorts stay dry to the touch and do not become heavy during high-output activity.
- Fit type
- The shorts are likely a relaxed, non-compressive fit, with the waistband sitting at the natural waist similar to standard athletic shorts.
