Frequently Asked Questions
Do I need a bladder or are soft flasks better?
Bladders offer larger capacity (2L+) and hands-free drinking, good for long runs or when you need to carry more water. Soft flasks are lighter, lower profile, and easier to swap/reload during shorter, faster runs. Choose based on distance, weight tolerance, and how often you need to refill on route.
How do I stop my pack from bouncing?
Tighten and position the chest and waist straps so the pack sits close to your spine; use a sternum strap to stop vertical movement and distribute load. Remove unnecessary gear to lower weight, and pick a vest/pack with a form-fitting cut designed for running rather than hiking.
How do I clean and maintain the bladder?
Rinse the bladder and tube after each use; use a wide-mouth opening or cleaning kit to scrub interior surfaces. Dry fully before storage to avoid mold. Replace bite valves and tubing if they become stiff or leak, and inspect seams and strap hardware regularly for wear.
