Hydro Flask, various sizes and colors. I have the black 21 oz.
I have mine for 2 years and counting. It’s insulated to keep the liquid cold without condensation, and leak-proof. It’s also very durable. I haven’t been very gentle with it, but it takes all the abuse without complaining. It already developed some dents and some scratches on the lid, but it hasn’t compromise the insulation. - JoshTheBat
Seconded. I have a 32 oz HF that I got for half off at an REI sale (because it was a discontinued color). Keeps ice in water for like two days if I forget to drink it (even in glaring hot sun) Never leaks. Hard to dent. Drinking mechanism flows well, but not so well that it will allow you to load yourself up too fast. Love it. - Cam
I’m loyal to the classic wide-mouth Nalgene with a guard. The 32oz size means that if I drink 2 of them a day, I’m set (since I also drink coffee + seltzer + etc). I don’t like drinking cold water (sensitive teeth) so the fact that it doesn’t insulate is a plus for me. I’ve tried the skinny neck Nalgenes, but something about them makes me feel like I’m choking on air, and it’s hard to fit big ice cubes in them.
They’re cheap, virtually indestructible, easy to clean, BPA-free, dishwasher safe. Replacement parts are not only easy to find, they’re *also* cheap. They also hold a full bottle of wine, for when you’re having sneaky picnics.
No, they may not be the prettiest or the trendiest, but you can pry my Nalgene out of my cold, dead hands. - queerveggie
I think I’ve tried at least a few dozen different water bottles from various Nalgenes to randos I’ve picked up on clearance shelves. One of those discounted bottles was a plastic Contigo, and since that purchase, I’ve bought several Contigo travel mugs, plastic water bottles with straws and without, and double walled stainless Contigos with and without straws. Since I’m as much of an expert as a person can be on these things, I’m confident in telling you that the double-walled stainless Contigo Autoseal is my favorite water bottle. A close second is any other Contigo Autoseal (the one’s without straws.) My little family of four currently owns eight of them in various sizes and colors. -Corey Foster, deals researcher
