- This perk affects the Courier's overall movement speed, even if they are fast traveling, sneaking, over-encumbered, or wielding a two-handed weapon.
- Light Touch and Tunnel Runner synergize well with this perk, granting the user more benefits while wearing light or no armor. Atomic! can further increase movement speed.
- Toughness allows one to negate the primary disadvantage of wearing light armor, which is lower DT.
