Ive had this 1 gallon hydro flask for a little over 6 years now, and to sums thing up its a great addition to have, I'm in the blue collar industry and in durability its a tuff son of a gun, I've dropped it 1000 times it still keeps living, my concern was the handle ripping but its just as good as the day i bought it, I've read some comments stating a leakage but the way it works is the lid it self has a gasket and an arrow to show which way it faces, place this thing firm and you wont have a problem, and now to get the the nitty gritty does it keep things cold? Well not the way you may expect it but yes it keep things cold, if you put ice it may hold a couple hours but melt eventually it doesn't make miracles, but the water stays as cold as Antarctica for at least 2 days. Does it keep thing warm i have no idea, and my only complaint is you cant find parts for this thing anywhere but over all its a great flask to have.

Couldn’t possibly overstate how huge it is compared to my 32oz hydroflask. Noticed there are less color options than before, black was the only option. Wish it was customizable with a straw and also boot. Requires two hands to drink unless you’re a bodybuilder or something. Hefty, sturdy, holds enough water to last me most of the day. I got tired of refilling my smaller bottle 5 times a day so this will fix that!

The 128oz. Hydro Flask Oasis is an amazing product. It is a perfect size for a family, a couple or a person who consumes a lot of water. It is an excellent product to fill up smaller Hydro Flasks that you use throughout the day. I filled the Oasis with cold water and it successfully kept the water cold for over 24 hours. No ice was required. The design of the
Oasis is great. There is a lid the width of the bottle that comes off for easy filling, and there is a smaller cap for pouring or drinking from. The Oasis has a smooth handle that made carrying easy. When full there is a good bit of weight to it given the capacity of the bottle but I never felt that it was too heavy.
Overall a well designed bottle that I would highly recommend.

There are a few minor flaws in the design. 1. There is no place to keep the lid once you open the flask to take a drink. It ends up where we have to keep it down on the floor for convinence. Not a great design. 2. There is no straw option for you to drink from. It always has to be a pour.
