NalgeneSustain Tritan BPA-Free Water Bottle Made with Material Derived From 50% Plastic Waste, 16 OZ, Wide Mouth

Perfect size to throw in purse or put in a standard sized lunch box. Does not fit the wide mouth splash guards. The seal is good and durability is excellent

This water bottle is SMALL, which at first I was a little unsure of but it turned out perfect for me (my hand is small too, but still covers this bottle impressively lol). I didn't want to carry around large bottles and I work in a hospital so I have plenty of access to filtered water everywhere. I don't drink a lot of water but I think for my size and activity level I drink enough and it varies day to day. I was always getting paper cups each day I worked and figured I should do better for the environment. But also, I wanted something wide-lipped to allow for ice to fall in and extremely simple for washing purposes; same reason I didn't want a straw bottle or any with a contraption or suction. This was wide rimmed and simple screw-on, so easy to wash and wonderfully sized to carry easily even in a large pocket, and I can refill whenever I want.FYI if it wasn't already clear this is NOT an insulating bottle. Ice melts in it easily and it doesn't impressively maintain water coldness but that wasn't important to me. This was exactly what I wanted 🥹 and if people want a slightly larger size, the 32 oz version was pretty nice too, I just returned it because it was slightly too large for what I wanted it for. If they had made a 20 or 24 oz wide-rimmed simple bottle I woulda gotten that instead :)

Perfect nalgene quality. Fits anywhere. No leaking problems. Nice and handy little water bottle. At a good price too.

These are the best kept secret in water bottles. The perfect size to fit in a small backpack for a day trip around town or to the park. And most importantly: I've never found a cup holder in a car they won't fit in-- including my son's car seat / booster seat.I wish Nalgene made more bottles in these smaller sizes. They are PERFECT!

Bought my first set of Nalgene water bottles in-store, but couldnt find them again recently, so ordered four online. They are simple, functional, sturdy, dishwasher safe, and attractive without any gimmicky attachments. It's the only brand I'll use from now on. One thing though: I will only buy the widemouth versions because it is a little harder to clean the smaller mouth versions, whether by hand or in the dishwasher.
