What’s the lightest insulated/vacuum water bottle that won’t let your liquid freeze in? I always just take a plastic bottle but then have to deal with it half frozen the next morning.
What’s a good vacuum style lid bottle everything I’m looking at has a screw lid.Here a few things I have found help. One a vacuum style lid is better , although always heavier. The screw lids can and do freeze up easily. Two, adding a little salt will lower the freezing point . I've used gatorade packets or similar that have some salt to lower the freezing point a few times .. however, when it is really bitter it can still freeze unless you add an extreme amount of salt
