Ultimately, you need your water supply to be able to endure a variety of conditions, be reliable for holding cold (or hot), hold up against getting knocked around, and not leak. 

Here are a few recommendations on how to stay hydrated on your next trip, plus the best YETI Yonder® Water Bottles and Rambler® Water Bottles and Jugs to make sure you never run dry.

How Much Water Do You Need While Fishing?

A standard rule: Drink at least half a liter (16–20 oz) per hour for moderate exertion. But when you’re fishing, there are extra factors that demand more water:

• Cold weather can be as dehydrating as hot weather. You’re still sweating, even if you don’t feel it, and the dry air in colder climates can sap your fluids. 
• Sitting still makes it easy to forget to drink. Thirst doesn’t always hit until you’re already dehydrated.
• Long days in the sun or heavy exertion (fighting a fish, wading currents, etc.) push your water needs higher.
