Slim insulated bottle with accurate capacity and strong portability
This is a well-built 21 oz insulated stainless bottle in a slim, tall form factor. The brand might be unknown to most but construction quality is quite good, easily standing up to the quality of most name brands. This one feels very solid for the price tier.The interior and base markings confirm 18/8 food-grade stainless. Machining is clean, threads engage smoothly, and the powder coat finish is even with no cosmetic defects.Capacity checks out. Based on internal measurements and volume estimation, it aligns closely with a true 21 fl oz rating rather than being undersized. The main internal diameter is roughly 60 mm with a tapered throat up to the 44 mm mouth opening.The double-wall construction provides a real vacuum insulation gap. Based on outer and inner diameter measurements, wall thickness supports proper thermal isolation rather than cosmetic insulation. In informal use, it performs in line with the advertised 12 hour hot and 24 hour cold rating. Not a miracle performer, just solidly good and predictable.The narrower profile (~72 mm outer diameter) fits easily in standard cup holders and backpack pockets. The smaller mouth favors controlled drinking over rapid ice loading, but normal ice cubes still fit.The lid seals securely and has good grip texture. This is a screw-top bottle rather than a quick-sip design, which improves leak resistance when carried in a bag.At $17.99, this is competitively priced for a true vacuum insulated bottle with verified materials and honest capacity. If you want a slimmer daily carry bottle that fits everywhere and holds temperature reliably, this is an easy recommendation.

Impressive how long it keeps drinks hot!
As someone who is outside in the cold most of the day, I never had a bottle that would keep drinks warm for hours like this one. It delivers on its promise of keeping drinks steaming hot.I primarily use it for my morning coffee. I pour in freshly made coffee, and even after 4-5 hours, it's still almost too hot to drink comfortably. The double-wall insulation is seriously impressive.Beyond the amazing heat retention, I love the practical design. The bottle is made from solid, food-grade stainless steel, so there's no metallic taste or odor. It hasn’t stained like all of the other insulated bottles I own. The leakproof lid gives me total confidence to throw it in my work bag without a second thought. The lid itself is easy to grip and open, even with gloves or mittens on.It's also incredibly easy to live with. It fits in my car's cup holder, cleans up easily, it's dishwasher-safe, and the sleek design looks great. It feels durable and built to last.If you're tired of your coffee going lukewarm in less than 2 hours, this is the solution. A fantastic, high-quality bottle that's perfect for commutes, the office, or outdoor adventures in cold weather. Im sure it will do just as great at keeping drinks cold once summer arrives. Highly recommend!

Simple and Durable
This is exactly what a water bottle should be - no gimmicks, just solid construction and smart design. It might look like a standard stainless steel bottle, but there are several features that make it stand out for me.The wide-mouth design is perfect. I absolutely despise bottles with straws (they're impossible to clean properly and just harbor bacteria), so having a simple, wide opening is exactly what I want. It also makes it so much easier to give the bottle a thorough cleaning, which matters when you're using it daily.Speaking of cleaning - it's dishwasher safe, which is non-negotiable in my busy household. I don't have time to hand-wash water bottles, and this one comes out of the dishwasher perfectly clean every time.The size is ideal. It holds a generous amount of water so I'm not constantly refilling, but it still fits in my car's cupholder without any issues. That's a surprisingly hard balance to strike, and this bottle nails it.The quality is excellent. It has that nice, substantial stainless steel feel that tells you it's built to last. The insulation works great too - my drinks stay cold for hours and hours, even on hot days.Honestly, this is one of those products we'll use until we lose it, because otherwise it would probably last forever. If you want a reliable, no-nonsense water bottle that just works, this is it.

Slim, Durable & Keeps Drinks Hot or Cold for Hours
I’ve been really impressed with this 21 oz insulated bottle. The stainless steel construction feels solid and well-made, with a smooth powder-coated finish that looks great in Sapphire Blue. It has a slim design that fits easily in my car’s cup holder and backpack side pocket, which makes it perfect for daily use.The insulation actually works. My coffee stays hot for most of the morning, and cold drinks stay chilled throughout the day without condensation on the outside. The screw-top lid seals tightly and hasn’t leaked in my bag, which is a huge plus.I also appreciate that it’s made from food-grade stainless steel and is dishwasher safe, making cleanup simple. For the price, the quality and performance are excellent. If you’re looking for a reliable, portable bottle that keeps drinks at the right temperature and doesn’t take up too much space, this is a great choice.

Great quality water bottle
This water bottle looks great & is great quality. It’s stainless steel on the inside and the outside is some sort of grippy plastic that’s comfortable to hold and has held up great, no scratches or dents and I bring it with me to work every day. It keeps my drinks hot or cold for hours. I have the blue color and it’s a really nice looking stormy grayish blue. I like that it just has a simple screw on top that doesn’t leak and isn’t complicated to use. It has a wide mouth too that’s easy to put ice, coffee, protein shakes, etc in, comfortable to drink out of, and is quick and easy to clean since it doesn’t have a lot of complicated pieces to scrub out. It’s a great price too and came with a cute sticker with the brand’s name and a Koala on it (which is really cute). I highly recommend this water bottle.
