Size Guide for Running Apparel Brands
Running apparel brands need fit-precise sizing across tops, shorts, tights, jackets. Performance fit (snug + stretch + reflective) matters more than fashion.
The Chart
| Product | Sizing | Fit Notes |
|---|---|---|
| Running top | XS-2XL by chest | Slim performance fit, sweat-wicking |
| Running shorts | XS-2XL by waist | Inseam options 3-9 inches |
| Running tights | XS-2XL by waist + hip | Compression fit |
| Running jacket | XS-2XL by chest | Layered fit allowance |
| Sports bra | Cup + band | Encapsulation for D+ |
FAQs
Compression vs relaxed?
Most running brands offer both. Compression for race-day + recovery. Relaxed for training. Stretch fabric across both.
Reflective sizing?
Brands sell reflective add-ons by waist circumference. Or built-in reflective panels in nighttime-specific gear.
