What to Look for in Athleisure as a Bigger Guy
When shopping for plus-size athleisure, prioritize:
- Stretch + Recovery: Look for fabrics with 4-way stretch that won’t lose shape.
- Breathability: Mesh panels, moisture-wicking, and ventilation zones.
- Longer lengths: Tops that don’t ride up, shorts that don’t bunch.
- Tapered without tight: Pants that fit the waist but don’t squeeze the thighs.
- Representation: Brands that show big guys in their marketing = green flag.
