White Vests

How to Choose a Running Hydration Vest 

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.
