Hydro Flask Insulated Food Container — 12 oz Koala Gray snack jar, TempShield® insulation & leakproof lid

Hydro Flask’s 12 oz Koala Gray insulated food jar is a leakproof, kid-friendly stainless steel container that keeps snacks hot or cold for hours.

If you pack lunches for school, daycare or weekend outings, having a compact, durable container that actually maintains temperature and survives backpacks makes life easier. This 12 oz Hydro Flask food jar combines double-wall TempShield® insulation with a grippy, easy-to-open lid and a protective Flex Boot so kids can carry it, open it and enjoy meals that stay fresh without spills.

How well does this jar hold temperature during the day?

The double-wall vacuum insulation (TempShield®) slows heat transfer so hot foods stay warm and cold foods stay chilled for many hours. It’s designed for typical school- or activity-day timeframes rather than long-term, multi-day storage.

• Double-wall vacuum insulation reduces heat loss and gain.
• 12-ounce capacity fits child-sized portions like yogurt, soup, or pasta.
• Stainless steel interior won’t retain flavors between uses.

Is the Hydro Flask food jar spill-proof for backpacks and lunchboxes?

The jar features a leakproof lid engineered to prevent messy spills when properly closed, so you can tuck it into a bag without worry. The grippy lid helps kids secure it tightly after eating, reducing the chance of leaks from movement or tipping.

• Leakproof design when lid is fully closed.
• Textured lid edge for easier child grip and twist action.
• Flexible silicone boot adds a protective barrier against drops.

How easy is the jar to clean and use every day?

Both the jar body and the lid are dishwasher safe, simplifying after-school cleanup. The wide-mouth opening makes scooping and wiping straightforward, and the smooth stainless interior resists staining and lingering odors.

• Dishwasher-safe lid and jar for quick cleaning.
• Wide mouth fits spoons and small utensils for easy eating.
• Durable stainless steel interior is low-maintenance and hygienic.

Will a child be able to open and handle it independently?

The design targets younger users with a grippy lid profile and a perforated Flex Boot that improves handling and protects the jar from bumps. These features help smaller hands get a solid purchase and reduce accidental drops.

• Grippy lid surface reduces slip for small hands.
• Perforated Flex Boot offers extra traction and impact protection.
• Compact 12 oz size is easy for kids to carry and hold.

Who is this for: parents and caregivers seeking a compact, durable lunch solution for children aged roughly toddler to elementary school. It’s suited to families who want an insulated, leak-resistant container for soups, warm lunches, chilled snacks or leftovers that’s easy to clean, tough enough for daily use, and available in bright, kid-friendly colors like Koala Gray.
