Hydro Flask vs Yeti: the lighter bottle against the one whose warranty we could read
OutdoorGearLab put them first and second. Hydro Flask publishes a 24-hour cold figure and weighs less; Yeti publishes a 5-year term and three caps. Hydro Flask's warranty page blocked every fetch, and this page says so rather than guessing.

The verdict
Spec sheet, side by side
The sourcing gap, stated
This site quotes warranty terms from the maker's page or does not score them. hydroflask.com returned 403 Forbidden to every fetch on 2026-09-21, including the warranty page; the Wayback Machine's capture of that page contains only a title, because the page renders its text with JavaScript. The product pages archived with readable text (the 32 oz Wide Mouth and 40 oz tumbler) give us capacity, weight, height and the 24-hour claim, and those are cited. The term itself is not, and rather than repeat what third-party blogs say Hydro Flask's warranty is, the card says “unverified.” That costs Hydro Flask points here and is the correct outcome for a site that promises every figure links to its source. The methodology explains the rule.
Weight and caps
Hydro Flask's Wide Mouth is the lightest bottle per ounce in OutdoorGearLab's table (12.8 oz at 20 oz; the maker says 0.97 lb at 32 oz), and it is the reason the bottle is the trail default. Yeti's Rambler 26 is 22.0 oz on OutdoorGearLab's scale with the cap, nearly double for a similar capacity. Both have wide mouths for ice. Yeti sells the Chug Cap, Straw Cap and HotShot Cap; OutdoorGearLab lists Hydro Flask's Flex Cap, Straw Lid and Flex Chug as options, which we could not verify on the maker's page. Hydro Flask's 40 oz tumbler is 1.27 lb and Yeti's 30 oz Rambler is 16 oz; the Rambler takes coffee and has the deeper lid catalog. Best insulated water bottles ranks both bottles in the wider field; best 40 oz tumblers covers Hydro Flask's tumbler.

Buy which
Buy Hydro Flask if
- Weight matters: it is the lighter bottle by a wide margin.
- You want a published cold figure (24 hours).
- You have read Hydro Flask's warranty yourself and are satisfied.
Buy Yeti if
- You want a term you can read today: 5 years, quoted.
- You want three caps sold by the maker.
- You want the tumbler that takes coffee (Rambler 30).
Or the bottle that beats both on paper: the Klean Kanteen TKWide, lifetime term, 66-hour iced claim, gasket kit, at best insulated water bottles.
How we scored this
Units we claim to have tested: 0
Plenty of sites say they filled every cooler on this list with ice and watched it for a week. We don't say that, and we say so on every page. What we do instead: read the maker's published capacity, insulation, dimensions and weight; quote the warranty term from the maker's own warranty page with the date we read it; check whether the latches, gaskets, plugs, lids and straws are sold as parts; and cite the third-party ice-retention tests (OutdoorGearLab, Outdoor Life, Treeline, Outside, Gear Patrol) as their measurements, never ours. Every figure links to where it came from.
Scores are editorial judgments from that documented research, not lab results. Commissions never set a score or decide a pick. The rubric and its weights are published.
Corrections & updates
- First published. Hydro Flask warranty unverified as of this date; will update if the page becomes readable.
Questions
Frequently asked
Hydro Flask or Yeti?
Hydro Flask is lighter, publishes 24 hours cold, and was OutdoorGearLab's Editors' Choice. Yeti has a 5-year term we can quote, three caps for sale, and was Top Pick. Hydro Flask's warranty page could not be read.
Does Hydro Flask have a lifetime warranty?
We could not read Hydro Flask's warranty page (403 on the live site, JavaScript-only in the archive), so this site does not state its term. Check hydroflask.com directly.
Which keeps water cold longer, Hydro Flask or Yeti?
Hydro Flask publishes 24 hours cold; Yeti publishes no figure. OutdoorGearLab did not separate them on retention in its table.
Which is lighter?
Hydro Flask: 12.8 oz for the 20 oz Wide Mouth vs 22.0 oz for the Yeti Rambler 26 on OutdoorGearLab's scale; 0.97 lb for the 32 oz Hydro Flask per the maker.
Did you test either?
No. Units we claim to have tested: 0. Scores are OutdoorGearLab's; specs are the makers'.

We don't claim to have tested these coolers or tumblers and we don't pretend to. Units we claim to have tested: 0. Specs come from the maker's own product pages (linked on every product), warranty terms from the maker's warranty page with the date we read it, and ice-retention measurements are attributed to whoever made them. Amazon prices change often, so we don't print them. Where a figure isn't published, we say so. Read the full method.
