LARS NYSØM Stainless Steel Insulated Water Bottle 500ml (Calypso Blue) – leakproof thermo flask for hot & cold drinks
Product description
If you’re trying to cut down on single-use plastic, a stainless steel bottle with insulation is usually where the decision gets real: it’s not just about carrying water, but keeping drinks usable on your schedule. This LARS NYSØM Stainless Steel Insulated Water Bottle comes in multiple sizes, and the 500ml Calypso Blue version is the one to look at if you want something practical for office days, yoga sessions, fitness trips or the daily commute.
The pitch here is straightforward: double-wall vacuum insulation for hot and cold drinks, plus a design aimed at leakproof confidence and measured sips. It’s the kind of bottle that doesn’t demand attention day-to-day, which is exactly what you want—though whether it’s the right fit depends a lot on how you typically drink (and how you transport it).
What it is and what it’s for
This is a reusable stainless steel drinking bottle with vacuum insulation, designed to handle both hot and cold beverages. The brand positions it as a functional alternative to plastic bottles, suitable for everyday routines like office use, yoga, fitness, or even in the car.
On paper, the most obvious use cases are: - bringing coffee or tea along without it going flat-temperature immediately - keeping water or juice cold during the day - using it for measured, controlled sips via the drinking opening
A simple example: imagine filling it in the morning with a hot drink before heading out, then refilling or topping up later—when you open it again, the whole point is that it should still be in the temperature “zone” that makes it enjoyable.
Thermal performance you can plan around
The insulation claim is clear: up to 12h hot and up to 24h cold, thanks to double-wall vacuum insulation. That doesn’t mean it will stay perfect forever (real-world conditions vary), but it does suggest the bottle is intended for commutes and day-long use rather than short “step outside” refills.
If you’re someone who often ends up settling for lukewarm coffee or warm water on the go, this is one of those bottles that aims to reduce that disappointment. If you’re only carrying drinks for a quick walk, you might not need quite this level of insulation—though a leakproof bottle is still useful.
Leakproof design and drinking comfort
The bottle is described as 100% leak-proof and designed to be easy to fill. The drinking opening is said to suit measured sips without spilling. That matters if you transport it in a bag, gym kit, or car where a “mostly fine” bottle can still become a problem.
Still, it’s worth keeping expectations sensible: “leakproof” generally depends on using the bottle as intended—fully closed, upright where appropriate, and not overfilled. If you tend to toss bottles into a crowded bag without checking the lid state, you may still find there’s a bit of user discipline needed.
Materials and build (what you’ll notice)
The bottle is made from 18/8 stainless steel. In plain terms, stainless tends to be the route people take when they want something that feels robust and doesn’t rely on plastic bottles for everyday carry.
The dimensions and weight for the 500ml bottle are also provided: height 23.5 cm, diameter 6.8 cm, and weight 280g. That weight is not tiny, but it’s in the normal range for insulated steel bottles, so it should feel manageable for most people—especially if you’re already carrying a bag.
One detail that helps buying decisions: it’s pitched as functional and uncomplicated. If you like your bottle to look “fine” and do the job without fuss, this brand’s approach is aligned with that.
Where it shines, and where it may fall short
This bottle seems best suited to people who want one container for more than just water—specifically hot and cold drinks across a typical day. The leakproof focus and the vacuum insulation times make it a sensible pick for office, fitness, commuting and travel.
It may not be the best choice if you only want water for short outings, or if you prefer a super-light bottle. Also, if you’re buying mainly for carbonated drinks, you may find stainless steel helps with that use case, but the entry information doesn’t spell out any carbonation-specific handling tips—so it’s worth being a bit cautious with how you store and open it.

Is it worth it?
Worth buying if you want a leakproof stainless steel bottle that’s actually built for hot and cold drinks throughout the day, with insulation rated up to 12h hot and 24h cold. It suits everyday commuters, gym-goers, and office users who don’t want to settle for lukewarm drinks.
You may want to skip it if you’re mainly after a lightweight water bottle for short trips, or if you often carry bottles without checking lids and orientation. In that scenario, even a leakproof bottle can end up feeling like a hassle rather than a help.
