GSI Outdoors, Microlite 1000 Twist 33 fl.oz. Vacuum Insulated Stainless Steel Water Bottle, Aqua

I was looking for a Thermos brand backpacker's vacuum bottle because the one I have, the spring-loaded top broke at the hinge.This holds a lot more, and needs some sort of grip due to the size, weight when full, and the coating. I found that the only way it keeps hot liquids hot anywhere near as long as it claims is if you pre-heat with boiling water for 10-15 minutes first, dump that and promptly fill with your hot beverage, and then don't open it. Only by not opening it, will it stay hot for a long time. If you try to drink directly from it with something hot in it, it's gonna burn, so I'd avoid that. The lid also will drip when you open it (from condensation or from sloshing--not too big of a deal, unless you don't want it to drip on something you'd rather not get wet), so keep that in mind.Cleaning is a pain if you put hot tea in it. Residue builds up quick and is tough to scrub out, even with a new 3M green pad. Need something stronger than just soap and water--like stainless steel cleaner, oven cleaner, or dilute hydrochloric acid. I don't know what type of "stainless" steel they used on the inside--probably not 440C or CM154 (what diving knives are usually made from).I haven't tried putting anything cold in it.It's otherwise sturdily built, cap doesn't leak (at least not whenever I've used it), and it holds a fair amount, though have to pour into a cup...might as well buy a smaller Thermos with a cup and pour-through top.

This product is heavier than plastic bottles but has a different purpose, keep colds cold, hots hot, and prevent fluids from freezing, which it does very well

I LOVE this bottle. I am horrible at staying hydrated but it’s true if you enjoy drinking out of your container you’re apt to drink more from it. It’s true

This keeps stuff just as cold as other top brands like hydro flask and yeti. It's also lighter, less expensive, and less likely to get an annoying dent on the bottom because it has a plastic or silicone bottom. The cap is attached, which you may like or not - it can get in the way, but you're not going to lose it.the edges of the steel mouth feels slightly thinner than the larger, pricier brands, a slight downside.
