Gaskets are consumables, whatever bottle you get, make sure you can source additional gaskets.

Youtuber "Miranda Goes Outside" just came out with a bottle that's supposed to resemble a Smart Water bottle in form-factor but have the entire top unscrew ( in addition to the narrow standard bottle cap) for easy cleaning.

Never had mold in my Camelbak chute

I had one that had little domes to form the threads and it cleaned easier.

I had a Zojiirushi in the past too. I agree, it takes too much effort to clean. I now use a wide mouth bottle that just has a screw top lid, no straw or drinking apparatus besides the large open mouth. No gaskets or anything else. It's only two surfaces to clean and requires no disassembly, other than taking the lid off. It's much easier to keep clean.

The brand doesn't matter. Just get a wide mouthed metal bottle of whatever cheap brand is around. None of them have engineered a new alloy that makes their bottles better or anything. Just make sure it's double-hulled if insulation is important, which most are.

Nalgene and a bottle brush.

I’ve used a single Sigg traveler bottle for ages, but I’ve had mold buildup on the cap seal. Luckily Sigg has the caps sold as spare parts, so I’ve only had to replace the cap a couple of times during all this time. But it’s been near 15 years I think now, lining intact and all. It’s got a bunch of dents from falling on hikes, sometimes down from pretty high cliffs, but I feel it only adds to its attitude sort of.

Not sure if I’d go for a Sigg today, I have stainless steel in my sights if this one ever proves ready for retirement, but Id definitely choose one that has either replaceable seals and seals sold as spare parts, or at least sells new caps as spare parts. And I’d for sure go with something similarly robust that can handle drops and getting banged around.

The cap design on the Sigg is pretty unbeatable though. It’s so natural for a finger when opening or closing and keeping the cap while drinking, but it also fits all sizes of carabiners or similar, so it’s just so handy to keep around on house but especially on hikes. I’m spoiled thanks to that, so I think there’s a high standard for whatever I’d choose next.

But I can really recommend the aluminum Sigg traveler. Today it has a lot more actually enticing competition, but it’s a classic choice at least around here in Northern Europe.

Edit: Worth noting; Siggs prior to 2008 had BPA in the lining. Mine has a yellow tint in the lining, which is the telltale sign of the BPA-free, safe one. Today, only the aluminium bottles are manufactured in Switzerland, the others are in China (which I think has been thanks to some brand-leeching Chinese acquisition at some point)

Edit2: I also have a lot of old military surplus water bottles from around Europe (similar form factor) simply because both my few-days-bag and longer hiking rig have MOLLE all over the surface, and the old ALICE (us standard from I think around 1970) and MOLLE (or similar, today almost everything in terms of military surplus has something that fits into it) pouches for the water bottles of that certain shape can be had for extremely cheap, and they are so robust in keeping them in place thanks both to the bottle shape and the MOLLE in general, and it’s so flexible.

I mostly use these to carry extra water as plan B but especially for boiling for food or coffee etc. all of them have a certain funky smell that never disappears, but I’ve tested them all by keeping plain water in them for a week or more, then pouring out and seeing how it looks to naked eye, and how it tastes. The smell on some of them can get into the water a little bit, but all taste normal and so far I’ve not got any problems from using them. I would assume the military of all institutions would take care to make these things valid for long term and active use, since, you know, water is pretty much the main driving force in ensuring troops can keep going. But because of the smell I tend not to go for them as the main bottle, ever.

I just use a plastic volvic bottle. They're usually fine for a couple of weeks. I guess it would depend what's in your local water supply.
