Ideus IDEUS Insulated Water Bottle 360ml/12oz (Stainless Steel, Leakproof) with Straw & 2 Lids

The essentials

If you’re buying an insulated bottle for school or day trips, the IDEUS 360ml/12oz from Ideus is built around a simple promise: keep drinks tasting the way they should for a good chunk of the day. It’s a double-wall vacuum insulated water bottle made from SUS304 18/8 stainless steel, and the manufacturer says it can maintain drink temperature for up to 12 hours.

It also leans practical for parents. There are two lids included: one with a pop-up straw and a safety lock, and another “spout” style lid. On paper, that means fewer bottle-drama moments—kids can sip the way they’re used to, and you’re not locked into one lid for everything.

Key features that show up in daily use

Where this bottle feels most thought-through is the mix of insulation + kid-friendly drinking options + leak prevention. When the lid is closed, it’s described as fully leakproof, which is exactly what you want for bags, lunchboxes, and those days when a bottle gets bounced around.

The straw lid uses a one-touch pop-up mechanism with a safety lock. That’s a helpful detail if you’ve ever dealt with a lid that gets knocked open. The alternative lid is a spout attachment type, which can suit children who don’t want the straw every time.

There’s also a removable silicone base. That kind of thing doesn’t sound exciting, but in real life it can help protect the bottle from knocks and scrapes—particularly when it’s treated like a transport item rather than a countertop accessory.

Insulation performance: what to realistically expect

The vacuum double-wall insulation is the headline. The claim here is up to 12 hours for maintaining temperature. In day-to-day use, that tends to be enough for a school day routine—think filling it in the morning, then relying on it to still be pleasant later.

That said, insulation can’t fight everything: how long it stays at the “ideal” temperature depends quite a lot on what you pour in, the starting temperature, and how often it’s opened. So it’s best viewed as “built for long stretches”, not as a guarantee that the drink will stay exactly the same from first sip to last.

Cleaning and convenience

This bottle is dishwasher safe. The entry also notes that the straw and the silicone ring can be removed and cleaned separately, which should make it easier to keep things hygienic without wrestling with hard-to-reach parts.

If you’re comparing it to basic bottles that only get a quick rinse, this is the kind of feature set that often makes parents happier long-term—less effort, fewer corners where residue collects.

What’s included and how the lids change the bottle

You get two lid styles: a pop-up straw lid with a safety lock, and a spout-style lid. That flexibility is genuinely useful when children are still figuring out what they’ll use consistently.

A micro example: imagine packing it for a school day. If your child prefers straw drinking, you’d fit the straw lid and close it with the lock. If they later decide they want a simpler sips-from-the-spout approach, you can swap lids without changing the bottle itself.

One limitation to bear in mind: the bottle’s core size is 360ml/12oz. For heavier drinkers or longer days, it may feel small compared with larger-capacity options.

Key takeaways: who it suits (and who should think twice)

It’s a solid pick if you want an insulated stainless steel bottle designed for children, with leakproof positioning when the lid is properly closed, and the choice of straw or spout drinking.

It might not be the best match if you’re after a bigger capacity for all-day hydration, or if your child is very sensitive to straw style lids and you prefer a single-lid approach from the start.

The stainless steel SUS304 18/8 and BPA-free positioning also matters for many parents looking for straightforward, everyday usability rather than complicated bottle care.

Buying verdict

Worth considering if you’re looking for a vacuum insulated 360ml/12oz bottle with two lid options, a straw with a safety lock, and leakproof claims when closed. It’s the sort of school-and-outings bottle that can reduce spills and keep drinks at a decent temperature for much of the day.

You may want to skip it if the 360ml/12oz size feels too tight for your routine, or if you already know your child will never use a straw-style lid.
