Choose a gear capacity
- Runs under 2 hours: 2 liters
- Runs 2-3 hours: 2 to 6 liters
- Runs 3-6 hours: 4 to 12 liters
- Runs over 6 hours: 6+ liters
Decide on bottles and/or reservoir
- Most vests are compatible with both bottles and reservoirs.
- Bottles are easier and faster to refill, usually holding 500 ml of water each.
- Bottles can be soft or rigid. Rigid bottles are more durable.
- Reservoirs hold more water, up to several liters.
Get the right fit
- Follow the manufacturer’s sizing guidelines.
- Choose a snug fit. (Measure your chest while wearing your sports bra.)
- Leave room for adjustment: The straps should sit in the middle of their adjustment range.
- Women-specific vests: offer fits optimized for the bust and shoulders.
