Frequently Asked Questions
Running vest vs hydration pack — what's the difference?
Running vests — race-cut, tight body fit, flask-based hydration, 6-12L capacity. Hydration packs — general outdoor, looser fit, bladder-based hydration, 10-20L+. For running specifically, get a vest. For hiking/commuting, a pack.
Soft flasks vs bladder?
Soft flasks (twin 500ml) — front pockets, easy to refill, no sloshing. Bladder (1.5-3L) — rear, higher capacity, slower refills. Modern race strategy: flasks for intensity, bladder for training.
How do I prevent chafing with a running vest?
Proper sizing (snug, no bounce), anti-chafe balm (BodyGlide) on shoulders before runs, merino/synthetic base layer (never cotton), and washing the vest regularly to remove salt buildup.
What capacity do I need for a marathon?
Road marathons with aid stations: 1L total (twin flasks). Trail marathons: 1.5-2L. Ultras: 2L+ with plan to refill. For hot weather, add 500ml.
