Klean Kanteen Wide Water Bottle with Loop Cap - Stainless Steel Water Bottle for Daily Hydration & Outdoor Use - Non-Insulated - BPA Free, Dishwasher Safe - Brushed Stainless, 40 oz

I have several of these, 2 sizes. Very tough. Single wall, so you can boil water in them if you need to. The caps are plastic, but I’ve never had a cap crack or break or leak. You can order a new cap, but I never had to. Much superior to even top quality Nalgene bottles, I think. They’re heavier, but there’s no way you’re going to poke a hole in one. Some of mine have many years of dragging around in different mountains, getting dropped, falling out of pickups, heating tea in campfires, freezing in the snow. Only thing is, the one I ordered never got delivered. They say it did, but it didn’t. It’s would be top quality though, if it would’ve gotten here.

Works great. Good size for going hiking. Wide lid for mixing in electrolytes and amino acids, etc. and for easy cleaning. Easily cleanable and replaceable gasket. The fold out handle on lid surprisingly useful for carrying back and forth when not stowed in my backpack side pocket. Great quality, looks great, and is lightweight.

I love this canteen. Plain and simple. Single-walled. Tight seal. I use it on camping trips, and love that I can set it directly on a fire (minus the cap) to boil water. Water tastes great in it, and it's got solid, good quality build. I've dropped it a handful of times, and while it does take on dings, I'm surprised by how small they are compared to how bad the drops have been. Works like a charm!

This is my second time purchasing this bottle (I lost the first one), and I love it! I don't like my water ice cold, and this bottle is an excellent way for me to lug around 40 ounces at a time without lugging around something massive. It doesn't insulate drinks and will sweat if you put cold water inside on hot days, but it's perfect for a room-temperature water drinker. My bottle has a few dents in it, but that's because I'm rough on my gear (it rolled under the car yesterday, ha) but it has held up very well.

Somewhat hard to open and dents easily when dropped. The cap holds a few drops of water so when you open it, sometimes water drips down. But doesn't leak when closed.

this water bottle is the best. having a higher capacity bottle means you'll have to refill it less often and serves a good motivator to drink more. i was looking for minimal branding so this definitely checks the boxes and is a water bottle i truly enjoy carrying day to day. it's not too bulky and even when fully filled, its not too heavy. you'll also find it easier to clean since it has a wide opening! keep in mind that this is a single-walled bottle so be careful – the metal will immediately conduct heat if you put boiling hot water inside. it's perfect for warm/room-temp though.

After just 9 days of use, the Loop Cap's inner seal broke and lets all liquid out from the container. The only thing keeping the liquid in is the silicone or plastic seal and it either came loose or fell off from twisting the cap wrong. Like with most drinking bottles, most caps will have its moment in not screwing on properly and you will have to unscrew it and set it on correctly to screw it on. However, apparently the event that you screw it wrong allows the seal to come off. This is a terrible design. It is terribly unfortunate that Klean Canteen--one of the more revered companies in the outdoor community--has produced such a terrible product. Anyone interested in this product should steer clear of it and find an alternative option. I do not recommend it at all.

Very good quality. Very happy with it

Superb bottle. Just single wall and easily dented if dropped. Really happy with the lid and the elimination of plastic.

Muito boa garrafa recomendo

Brilliant service. Ordered two but only sent one and only billed for one. Fantastic bottle for bikepacking and other adventures.

Great water bottle. Sturdy with a wide mouth

La botella me encanta, de verdad se siente de calidad y mantiene el agua fresca. Sin embargo a veces, muy rara vez, pero me ha pasado ya tres veces en 6 meses, al momento de cerrar la botella el sello o empaque se sale de sitio y cae dentro del líquido sin que lo notes. El problema de eso es que si la guardas en la mochila tu computadora morirá. Las tres veces se derramó dentro de mi mochila pero las primeras dos veces me di cuenta y vacíe la mochila, sequé todo y no hubo mayor problema. Pero la tarcera vez que me pasó, tenía muy poca agua y sólo se humedeció la mochila quedándose así por toda la noche. Al día siguiente saqué la laptop y estaba húmeda, como el espejo del baño después de la ducha. Obviamente la computadora ya no sirvió por la corrosión en la placa madre. Disculpen que salga del tema, pero como una botella aparentemente de calidad y un precio tan elevado puede tener una falla de diseño así de malo y abusado, me parece una falla tremenda. Por lo mismo la botella me acabó saliendo 20 veces más cara por la computadora que se descompuso. Ahora lo que hago es voltearla cuando la cierro para asegurar que no tenga fugas, además de tenerla que cargar siempre en la mano por si de alguna forma misteriosa el sello vuelve a salirse de sitio durante el transporte.
