Hydro Flask Standard Mouth Water Bottle vs Nalgene Wide Mouth Water Bottle

Analysis:

The Hydro Flask Standard Mouth Water Bottle (21 Oz) is one of the very best Traditional Water Bottles that one can get for around $35. The Nalgene Wide Mouth Silo Water Bottle (48 Oz), however, while a very good choice at its $13 price point, falls just short of being remarkable.

The Hydro Flask Standard Mouth Water Bottle (21 Oz) has done great in quite a few roundups from some of the most highly trusted sources available, such as Wirecutter, Tom's Guide, and OutdoorGearLab, which perform high-quality in-depth testing. It got awarded the "Top Pick" title by Wirecutter, "The best overall water bottle" by Tom's Guide, and "Ranked 1 out of 18" by OutdoorGearLab in their respective roundups. Earning that much praise from such respected sources is undoubtedly an impressive accomplishment.

As for the Nalgene Wide Mouth Silo Water Bottle (48 Oz), it was really well-received by reviewers at OutdoorGearLab, a reliable source that's known for conducting its own, high-quality, in-depth testing. It performed great in its "The Best Water Bottles of 2020" roundup and was named its "Best Bang for the Buck", which, on its own, makes it a product that warrants a closer look.

We examined all of the review data that we could find and first took a look at sources that reviewed both of them, like OutdoorGearLab, and found that they haven't shown a preference for either product.

Then we checked which sources liked these two Traditional Water Bottles best and found that the Hydro Flask Standard Mouth Water Bottle (21 Oz) got its highest, 9, review score from reviewers at Top Ten Reviews, whereas the Nalgene Wide Mouth Silo Water Bottle (48 Oz) earned its best score of 7.6 from OutdoorGearLab.

Lastly, we averaged out all of the reviews scores that we could find on these two products and compared them to other Traditional Water Bottles on the market. We learned that both of them performed far better than most of their competitors - the overall review average earned by Traditional Water Bottles being 6.4 out of 10, whereas the Hydro Flask Standard Mouth Water Bottle (21 Oz) and Nalgene Wide Mouth Silo Water Bottle (48 Oz) managed averages of 8.3 and 7.6 points, respectively.

Due to the difference in their prices, however, it's important to keep in mind that a direct Hydro Flask Standard Mouth Water Bottle (21 Oz) vs. Nalgene Wide Mouth Silo Water Bottle (48 Oz) comparison might not be entirely fair - some sources don't take value for money into account when assigning their scores and therefore have a tendency to rate more premium products better.
