- side_splits
- Side hem splits improve stride freedom at some cost to coverage
- care
- Machine wash; do not bleach, tumble dry, iron or dry clean; hang to dry
- wash_frequency
- Wash after each use because the liner touches skin; air dry ready for the next day
- durability
- Silicone logo on stretch fabric tends to keep shape and lose some sheen; edge stress is possible if elasticity is mismatched
- styling
- Marbled charcoal outer with solid black liner creates a layered two-tone sport look
- comparison_padded
- Unlike padded cycling shorts, this has no chamois; for long rides use a separate padded liner
