A Guide to Water Bottles for Hiking in 2020

Woman hiking with a water bottle in handHiking is the ultimate activity for the lovers of the great outdoors. It can help you get up close to nature, break some sweat, and stay fit. However, hiking can be quite taxing on your body, especially if you are doing it on hilly terrain. You will lose a considerable amount of body water through sweating, which is why you need to hydrate properly before, after and throughout your hike.

Whether you’re a veteran hiker or a rookie, it pays to have the right water bottle for hiking before you hit your trail. That’s why we’ve put together a review of the 8 best water bottles for hiking. 

Before we delve right in …

Choosing the Perfect Water Bottle for Hiking – What to Consider?

There are several attributes of the best water bottle for hiking, but here are the most important ones:

Medium-High Capacity – Any water bottle with a capacity lower than 18 fluid ounces (half a liter) is a big no-no for hiking. On the flipside, one with a capacity larger than 32 fluid ounces will bog you down during your hike. So, choose one with a capacity that falls between 18 and 32 fl. Oz.

Insulated – Insulation is an absolutely crucial feature if you want your fluids to remain cold or hot during your hike. This is especially important for summer and winter hikes.

Wide Mouth Opening – If you’re planning to refill your water bottle for hiking frequently, be sure to choose one with a decent mouth opening. The same goes if you’ll be carrying something like smoothies or chunky soup.

Lightweight is Great – It’s a no-brainer that you don’t want a water bottle that will strain your hands during hiking.

Durable – Collapsible water bottles are usually ideal for hiking, but are they durable? If this is an issue for you, a stainless steel water bottle should be your go-to.
