My hydroflask I’ve had since 2015. There’s so many dents on it I’m surprised it’s still holding up. I don’t use it as much now, but it’s still in rotation from time to time.

Nalgene is great and light weight. I cracked one once, dropped it full of water, and they replaced it for free. I just sent photos of the cracked bottle.

Yeti 64oz is a beast and is my current daily driver. I dislike the taste of water in the office so I bring water to work every day.

Other bottles I’ve had along the way zojirushi thermos- got it in 09 for mixing baby formula. Keeps hot things hot too well IMO. My parents use it now. Camelbak chute- both plastic and stainless steel. Works well, insulation is pretty minimal for the SS one. Quality on par with naglene for plastic version
