Thermos 530ml Stainless Steel Hydration Bottle, Slate Blue — 14 Hours Cold! $43.29 CAD (32% Off)

Thermos rates it for 14 hours cold, and the reviews back that up: leave it in a hot car all afternoon and the water is still cold. Double-wall vacuum insulation means no condensation on the outside and no ring of water on your desk. The lid is push-button with a locking ring — thumb to open, press to close, flick the ring and it won't leak in a bag. One hand the whole way. There's a silicone sleeve for grip, the diameter is sized for most car cup holders, and it's dishwasher safe.

Two flaws come up again and again in the reviews, and they're worth knowing. It's tall and slim, so it tips easily — and a single drop can crack the lid, which retires the whole bottle since Thermos doesn't sell replacement lids. And the mouth is narrow enough that ice cubes spill over the edge when you fill it from the fridge dispenser.

4.7 stars over nearly 2,000 ratings, #880 in Insulated Bottles. One reviewer has been using this model since 2017 and now owns three; another tried a couple of other brands and came back. If "still cold at 4 pm" is the thing you care about, this is one of the better bottles for the money.
