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
- Eight-day and three-week wear tests confirm Polygiene-treated polyester stays odor-free without washing.

- 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

- Movement fit details
- Bonded hem, side slits, and fake fly reduce chafing and restriction; flush zip pocket prevents swing.
- Unlined construction

- 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
