The J1B Solution
Created to give you the benefits of metal and
glass while overcoming their problems.
People who regularly drink from plastic bottles consume around a credit card's worth of plastic… every week. That’s more than eating your Airpods, case and all, every single year. Not to mention the environmental implications of plastic bottle use. Like most people, we at JustOneBotl don’t subscribe to this lifestyle. We prefer insulated glass, so that’s what we made.
Metal is porous, which means it retains bacteria more stubbornly than plastic or glass. That’s why you can never fully get rid of those lingering tastes from drinks other than water. You also can’t see what you’re drinking. We think you deserve to pour more than just water in your bottle and hope you do too.
There is a reason fine wines are served in glass. Glass containers are the purest way to drink any liquid. But glass breaks easily, doesn’t regulate temperature, and like plastic, it sweats. We want the pros without the cons, so that’s what we made…

Absolutely love the cup. It is so versatile. You can use it with or without the double wall metal you can drink just with a glass you could drink just with the metal two different top one with a straw one without it’s just an awesome cup great for sharing. Just awesome overall very solid versatile cup that everybody should own.
Love this bottle! It keeps my water cold for hours, doesn’t leak, and the grip makes it really comfortable to carry. Great quality and perfect for everyday use!
This is an awesome water bottle. As someone that travels frequently I’m always on the lookout for a good water bottle something I’ll keep my ice water cold or my coffee hot. This bottle is well made, and does just that it keeps my beverages just the way I want them. The only thing I could suggest is a larger size. I would’ve loved this to have been a 32 ounce bottle just for my personal taste, but this bottle works perfectly fine for reviewing the features.
This is the second time I’ve received the justONEbotl and I’m still loving it 😍. I love that it keeps my drinks cold for 24h and hot for 12h, plus it’s stylish, lightweight, and easy to clean. I use it every day for water, coffee, and shakes – super practical!
Works great! Love the versatility of it. My only disappointment was I went hiking with it and banged it against some rocks and the coating got scratched. I guess that is on me though.
I recently purchased this water bottle, and I must say, it has exceeded my expectations. The standout feature of this bottle is undoubtedly its ability to keep drinks warm for an extended period. Whether I'm enjoying a hot tea or need a warm beverage during a long day at work, this bottle ensures my drink remains at the perfect temperature for hours. The construction of the bottle is impressively sturdy. It feels robust in hand, and the materials used in its making clearly speak to its durability. I've accidentally dropped it a couple of times, and there have been no dents, scratches, or any noticeable damage. This bottle is built to last. One of the features that I particularly appreciate is the interior made of glass. This not only ensures that my drinks taste pure and untainted by any metallic flavors, but it also adds an element of elegance to the bottle. The combination of the sturdy exterior and the glass interior strikes a perfect balance between durability and sophistication. In conclusion, this water bottle has become an essential part of my daily routine. Its ability to keep drinks warm, combined with its sturdy construction and glass interior, makes it a top-tier choice for anyone in need of a reliable and stylish beverage container. I highly recommend it to anyone looking for a high-quality water bottle.
Okay dude, I dunno if anyone has told you this yet, but you made a legit banger with this. I might (...MIGHT, mind you) have other bottles that keep iced water colder longer. And I definitely have bottles that hold more. But this one still tops my list as my favorite for a couple of reasons. One of which you may not even know as I don't know that you'd even think to test for it: 1. The size is pretty much perfect. I love how sleek and slim it is (tradeoff for the smaller capacity, sure, but for me it's worth it). 2. This bottle appears to keep UN-ICED water cold for way longer than I expected it to. It's been a standard part of my routine as I get ready to play disc golf since I got it, and I'm telling you that I can pour fridge water, with no ice, in this bottle, and by the end of my 9 or 12 hole rounds, it's still refreshingly cool. It does get a bit lukewarm if I try to go a full 18 holes, but that's a rare problem, as it's not easy to make 15 oz last for 18 holes in the sun anyway. That second one is a real winner for me, because I used to always dread that last drink from my water bottle, as melted ice tastes way different than water. With J1B, I don't have that issue, and I still have cool water to drink as the last swig from it. I just really like this product. :)
Just one botl! Like it says, all you need is just this one. Multipurpose and does it all. Highly recommend!
Just One Botl is amazing! I just love the color and how this is microplastic free. Will definitely be buying more later this week for my family!
I love this bottle. It is multi use and really well build.
This bottle is truly amazing! When it is in its hybrid configuration no plastic touches the bottle contents and it's able to be used as two separate bottles if desired. You have a metal thermos that you can use by itself and a glass bottle you can use by itself. You can also be separated in a way that allows for the medical components to act as cups! It's dishwasher safe and BPA free and you can hold hot drinks hot for 12 hours or cold drinks cold for 24 hours plus I love the color :) buy it!
The inherent design of the glass bottle and the stainless steel fitting into each other is genius in it's ability to float, insulate, compact, and protect, it's just that there were a few problems, like bits of plastic on the thermos lid's attachable mouthpiece and extendable carrying hook, which does not give me the most faith in the plastic parts quality, and on top of that the thermos lid would not close if the glass bottle was inserted as shown in the video. Otherwise I love the concept and most of the execution, and would recommend glass bottle enjoyers to get the JustONEbotl, just with the understanding that there's still kinks to be fixed.
Store owner replied: Hi Chancelor - Thanks for your review. We can fix the problem you are referring to — the cap not easily closing — will call you tomorrow to address it.
I loved it super material and very practical, the color fascinates me
I loved it. It has a great quality, I recommend it and I would order again without hesitation.
It’s a very practical and truly beautiful product.
This bottle has a glass inner liner, which I really like. It keeps the taste clean and fresh. The outer design feels sturdy and comfortable to hold. I enjoy using it every day.

Great product i love it.
My experience has been excellent; I honestly loved it. I’m planning to make a video showing it in detail because I was really impressed with the quality of the materials and all the accessories it comes with. Everything exceeded my expectations, and I’m very happy with the purchase❤️
The J1B glass bottle truly exceeded my expectations. Its modern, minimalist design pairs perfectly with the high-quality materials. The glass body feels sturdy and well-protected, while the interchangeable bands add a personalized touch and improve the grip—both stylish and practical. The lid is secure, easy to open and close, and prevents any accidental leaks. It keeps drinks hot or cold for an impressive amount of time, making it perfect for everyday use. The bottle is lightweight, easy to carry, and clearly designed with comfort and functionality in mind. Overall, the J1B glass bottle is an excellent blend of aesthetics, durability, and smart design. Definitely a highly recommended purchase for anyone looking for style and quality in one product.
A very sturdy and practical product, I highly recommend it
I really like this bottle — it’s stylish, durable, and keeps my drink cold for hours! The color “Empire Blue” looks amazing. Highly recommend! 💙
This product is amazing!😍😍😍 It keeps things cold or hot for a long time. It's very useful for carrying liquids when you're out and about. A great buy!🎀💕
I honestly didn’t expect to be this impressed by a water bottle. But this one lives up to its name - it really is just one bottle that does everything. The design feels super solid and the way all the parts fit together is so smart. I use it for coffee in the morning and water at the gym and office later, and it keeps both at the perfect temperature. What I love most is how sleek and minimal it looks, but still has so many features hidden in it. You can tell they’ve thought through every detail. If you’re tired of switching between bottles or mugs, this is genuinely the one to get.
I loved the product, useful and of good quality. Ideal for my gym routine. Thank you for the article
Love the multi-use bottle and the reduction of micro-plastics!
The perfect bottle for on the go! Very versatile!
I’m loving my experience with justONEbottle! It keeps me hydrated all day, is super practical, and the design is gorgeous.
The bottle is very versatile. It comes with multiple attachments to make it fit any need! It is very sturdy and comfortable to use. The bottle easily fits into any cupholder. The bottle has a handle that comes out, which makes it very convenient for transport. Would highly recommend!
Awesome company to work with and great interchangeable Water / Juice bottles! Highly recommend JustOneBotl.com 💙💙💙
Perfect product🫠
Best bottle ever created, I absolutely love it. Great for juices, water, hot drinks or any other liquid you wanna get into it. It’s perfectly designed, versatile and resistant, I’m so readyto go on many adventures with my bottle. 🤩💧
I was amazed at the versatility of this bottle to serve many purposes as I rucked Manhattan for a week. I loved them so much, I bought two!!
La mejor botella de agua que e probado!! La utilice con agua fria para ir a la playa y de regreso a la ciudad la utilice con agua caliente para prepararle la mamadera al bebe!! Love it!!
This bottle is brilliantly designed—practical, stylish, and perfectly serves my needs.
This really is an amazing bottle. I was never a fan of reusable bottles but I’m now converted! This bottle can be used in multiple ways that truly work and it keeps my drinks chilled, perfect for a summer day out. Plus it just looks so aesthetically appealing! I don’t have to worry about microplastics, it’s easy to clean, and a true life changer. Such a fan!
My bottle arrived at the perfect time! I brought it to an outdoor concert, and it kept my drink perfectly cool the whole time. I absolutely love it. It's so cleverly designed! Versatile, stylish, and sustainable. I especially love drinking out of glass instead of plastic. Just one bottle is all I need! Thank you!!!!!
I love this bottle — super cool how it has multiple uses — glass and stainless steel insulation. Highly recommend. Absolutely love it!
This bottle is a great option, and maybe the only option, if you both want to drink out of only glass, avoiding microplastics and the taste altering of metal, and to have an insulated bottle. This was perfect for my mom who wanted exactly that. Glass bottles are uninsulated or fragile, and insulated bottles aren’t glass. Comes with lots of lid options and the transformation into two bottles could be useful for traveling.
This bottle is so versatile! I can use it for hot liquids as well as cold or use it as a thermas or as a water bottle. I love the array of attachments as well. The designer of this bottle is a genius for coming up with such an efficient yet classy design!
Frequently Asked Questions
Everything you need to know before choosing your JustOneBotl.
It is two bottles in one. A 15 oz tempered borosilicate glass bottle sits inside a 22 oz double-walled stainless steel bottle, so you drink straight from the glass while the steel handles the insulation and protects it. You get the performance of steel with the clean taste of glass, and your drink never touches metal or plastic. Separate the two and you have a second cup, plus the outer shell doubles as a koozie.
For a detailed overview on how to use the bottle, watch the video here.
The outer shell is double-walled SS304 (18/8) stainless steel. The inner bottle is tempered borosilicate glass, so your drink never touches metal or plastic.
It stands about 9.25 inches tall and 2.56 inches wide. The steel shell holds 22 oz and the glass insert holds 15 oz. Apart, the glass bottle weighs 265 g and the steel bottle with its cap weighs 337 g.
Your order includes the bottle and the accessories shown on the selected product page: a 15 oz borosilicate glass bottle, a 22 oz double-walled vacuum-sealed 18/8 stainless steel bottle, a flip cap with a modular spout, a straw cap and a metal screw cap.
Yes. The double-walled vacuum insulation keeps drinks cold for about 12 hours and hot for about 10. The same insulation keeps the outside dry and reduces condensation during normal use, although performance varies with the drink temperature and the surrounding conditions.
Yes, when the cap is closed properly. The screw cap, the flip cap and the straw cap are all leakproof.
Yes. Coffee, tea, soup, juice and protein shakes are all fine. Because the inside is tempered glass, your drink stays clean with no metal aftertaste.
Yes. The removable parts are designed to make routine cleaning quick and convenient. Follow the care instructions supplied with your product for the best results.
