When I first started training for ultramarathons and running to and from work with a hydration pack, my coworkers teased me for looking nerdy. But runner nerds are on the rise, embracing hydration packs as a badge of honor for serious miles. The Nathan Laser Light 3L Hydration Pack ($100) is a standout choice, offering hydration, storage space, and visibility when running in the dark. This lightweight pack is comfortable and secure, with an adjustable fit and easy-to-refill bladder. While it may require a strong sip to get the water through the straw, its integrated LED light enhances safety during low-light conditions. Check out our review to learn more about this top-notch hydration pack.
