I'm in the market for a ~40oz/1L sized thermos bottles.
Most of them claim to keep liquids cold/hot for 12-24 hours, which is great and all but I can't imagine needing to hold it that long. I'm more concerned about durability and leak proof.
The actual Thermos brand ones seem to be rated highly and can be bought for under $40 pretty regularly.

Any recommendations?
