TL;DRThe Short Answer: Is the Hydro Flask Food Jar Worth It?

Leak-proof and built to outlast just about anything else in the lunch bag, the Hydro Flask 20 oz Food Jar trades a bit of raw heat retention for a wide mouth that actually makes eating soup or stew easy.

NoFussDeal rates the Hydro Flask Food Jar 4.4 out of 5 at $39.95. Last updated September 27, 2026.

What Stands Out

  1. TempShield double-wall vacuum insulation keeps hot food hot and cold food cold for hours
  2. 20 oz capacity with a wide-mouth opening that fits chunky stews and full-size spoons
  3. Durable stainless steel construction, built to withstand daily bumps and drops
  4. Leak-proof design when closed, so it can go in a bag without worry
  5. Compact, single-hand-portable design that fits easily in a lunch bag or backpack

Strengths and Drawbacks

What works

  • Wide mouth allows full-size spoon entry and direct eating without bowl transfers, accommodating chunky stews and pasta
  • Keeps hot soup and meals warm for hours in most cases, especially with a quick preheat before filling
  • Leak-proof when properly closed, so it can go in a bag with no spills
  • Exterior finish provides a secure grip even with wet hands and resists scratches through daily use
  • Wide mouth allows hand-entry cleaning, unlike narrow-mouth designs that need a specialized brush
  • Exterior stays comfortable to hold even with hot contents inside
  • Durable stainless steel construction that holds up well for years

What does not

  • Silicone gasket will eventually need replacing as it wears from repeated use
  • No integrated carry handle requires two-hand operation when opening with tight lid seal
  • Can feel heavy for younger children to carry once filled

Features in Depth

01

A 20-Ounce Wide-Mouth Jar Sized for a Real Meal

Capacity 20 fluid ounces Shape Cylindrical, wide mouth Weight 0.5 kg

Hydro Flask makes this food jar in 20 fluid ounces: a cylindrical, wide-mouth stainless steel container that weighs 0.5 kg. That is enough for a proper lunch rather than a snack. The size is right for soups, stews, pasta and hearty salads, and it holds a full bowl of soup. The wide mouth makes it easy to fill, eat from and clean, a real everyday advantage. Hydro Flask sells the food jar in several sizes, so make sure you pick the 20 oz one if you want a full meal.

Vacuum-Insulated Stainless Steel With TempShield

Material Stainless steel, vacuum insulated Insulation TempShield double-wall vacuum Quality Positive theme

Hydro Flask uses double-wall vacuum insulation, which it calls TempShield, to keep food hot or cold for hours, inside a body of durable pro-grade stainless steel that is BPA free. Quality and durability are strengths, and the jar can last for years. The pure-taste claim addresses a real practical concern: stainless steel resists absorbing and transferring flavours between uses the way some plastic containers can, so, as Hydro Flask puts it, today's yogurt won't taste of yesterday's mac and cheese. The soft-grip lid seals tight and, Hydro Flask says, is easy to open.

Leakproof When Closed, Dishwasher Safe, Temperature Retention Is Mixed

Leakproof Positive theme (when closed) Temperature Retention Mixed theme Care Dishwasher safe, airtight

Leakproofing and ease of cleaning are strengths. Hydro Flask says it is leakproof when closed, rates it airtight, and makes both the lid and jar dishwasher safe, designed to keep their bright colour through repeated washes. The lid stops spills even with soup carried in a bag. Temperature retention is less consistent, along with functionality and value for money: soups and pasta can stay hot for hours, and it will even make porridge from oats left in boiling water for an hour, but some jars do not keep food warm. If you need food properly hot at lunchtime, expect some variability.

Lifetime Warranty and the Verdict

Strongest Themes Quality, size, leakproof Warranty Lifetime Mixed Theme Temperature retention

Quality, size, leakproofing, ease of cleaning and durability are all strengths, and most people are very happy with the jar. Size stands out: it suits soups, stews, pasta and hearty salads, and holds a full bowl of soup, so this is a meal rather than a snack-only portion. Hydro Flask backs it with a lifetime warranty, strong cover for something you will carry every day. Temperature retention, functionality and value for money are more mixed, so this is a sound premium choice for hot or cold food on the go, provided you accept that heat retention varies from jar to jar.

How We Scored It

Based on
The manufacturer's published specifications and the product's live Amazon listing.
Owner rating
4.4 out of 5 on Amazon, recorded September 27, 2026
How we score
We score each thing that comes up most in owner feedback on the Hydro Flask Food Jar. Eight things come up most in owner feedback: five draw praise and three split opinion. Its ratings average 4.4 stars (76% five stars, 8% four, 6% three and 10% one or two), so every score starts at 88, that average on a 100 point scale. Where opinion is split, we take off 6. Where it draws mostly complaints, we take off 12. Then we read six owner reviews in full (every one we found gave it four or five stars) and move the score up to 5 points either way depending on how the owners who mention it rated the product. Our overall score starts from the same 4.4 star average and loses 0.1 for each thing that draws mostly complaints, with 0.1 more when at least a tenth of ratings are one star, never more than 0.3 in all. Nothing comes off here, so it stays at 4.4. Read our editorial standards

Setting It Up

  1. Initial Cleaning

    Wash jar, lid, and gasket with warm soapy water before first use. Remove silicone gasket from lid for thorough cleaning of all surfaces. Rinse completely and air dry all components.

  2. Preheat for Hot Foods

    Fill the jar with boiling water, secure the lid, and let it stand for a few minutes to warm the stainless steel walls before adding your food. This can help the jar hold heat longer. Empty the preheating water before adding food.

  3. Fill to Proper Level

    Add food while it's still hot, or well chilled if serving cold, for the best results.

  4. Secure Lid Properly

    Thread the lid on until it feels fully seated and won't turn further. Check the seal by gently tilting the jar before packing it in a bag.

Common Questions

How much food does the 20 oz jar hold?

It holds 20 fluid ounces, enough for a proper lunch: it fits a full bowl of soup, and suits soups, stews, pasta and hearty salads. Hydro Flask sells the food jar in several sizes, so make sure you choose the 20 oz version if you want a full meal rather than a snack.

Does it actually keep food hot for hours, or is that exaggerated?

Results vary. Soups and pasta can stay hot for hours, and it will even make porridge from oats left in boiling water for an hour, but some jars do not keep food warm. Hydro Flask says the double-wall vacuum insulation keeps contents hot or cold for hours, but expect some variability rather than guaranteed all-day heat.

Is it really leakproof for soups and liquids?

Yes, when the lid is properly closed. Leakproofing is a strength, and soups can travel in a bag with no spills. Hydro Flask says it is leakproof when closed and rates it airtight.

Will it hold on to smells or flavours from previous meals?

Hydro Flask says its pro-grade stainless steel keeps a pure taste with no flavour transfer between meals, so yesterday's mac and cheese should not flavour today's yogurt. It is also BPA free, and its quality is high.

Can I put it in the dishwasher, or does it need hand washing?

It is dishwasher safe. Hydro Flask says both the lid and jar can go in the dishwasher, and the jar is designed to keep its bright colour through repeated washes. Cleaning is easy, and the wide mouth helps.

What does the lifetime warranty actually cover?

Hydro Flask backs the food jar with a lifetime manufacturer warranty, strong cover from an established brand. Check Hydro Flask's warranty page for the specific coverage details and how to file a claim.

The Verdict

4.4Out of 5

The Hydro Flask 20 oz Food Jar delivers on its premium positioning with genuinely leak-proof reliability and durable stainless steel construction that lasts for years. The combination of TempShield vacuum insulation and a lifetime warranty justifies the cost for daily users prioritizing accessibility and build quality, even though pure heat retention is mixed rather than universally excellent. Minor limitations include an eventual need to replace the gasket and a heavier feel once filled, which can challenge younger users. The jar excels in its intended role as a wide-mouth thermal container for a single meal on the go, making it a strong choice for office commuters, outdoor workers, and anyone who values easy cleaning and direct-eating convenience.

Who should buy it

  • Office workers and commuters needing reliably warm food for desk lunches with easy wide-mouth access
  • Outdoor workers and construction professionals requiring durable, leak-proof food storage that withstands job site conditions
  • Parents packing school lunches who prioritize food-safe materials and easy cleaning over maximum thermal performance
  • Camping and hiking enthusiasts wanting single-meal hot food storage with proven durability and portability

The Hydro Flask 20 oz Food Jar justifies its premium price with genuine advantages in leak-proof reliability and durability that budget options can't match, backed by a lifetime warranty. While the wide-mouth design isn't the most thermally efficient shape for pure heat retention, the usability gains for chunky foods and easy cleaning create real value for anyone prioritizing daily convenience. With reasonable care around the gasket, it's built to last for years, making it a strong choice for people who want dependable, high-quality food storage without gimmicks.
