IRON °FLASK 40 oz Insulated Water Bottle — Ice Stays Put All Day! $22.99 CAD (39% Off)

Amazon.ca has the IRON °FLASK 40 oz (1200 ml) Insulated Water Bottle for $22.99 CAD (list $37.99, 39% off). Prime members ship free; otherwise free shipping on orders over $35.

Double-wall vacuum insulation with 18/8 stainless steel: cold for 24 hours, hot for 12. Fill it with ice water, leave it in a hot car all day, and there's still ice at night — the single most repeated line in the reviews, and the practical difference from a $20 supermarket bottle. The exterior doesn't sweat, so it won't soak your laptop in your bag.

It ships with the leak-proof straw lid and a carabiner, so it clips to a backpack strap or stroller and you drink one-handed without unscrewing anything.

40 oz is the "fill it in the morning, refill never" size. At 445 g empty it's not light, but you weren't going to carry it around all day anyway. 18/8 stainless leaves no metal taste and won't rust, and the mouth is wide enough to drop ice cubes straight in.

One caveat: hand wash only. The coating doesn't survive a dishwasher.

4.6 stars across 83,000+ reviews — holding that score at that volume says the quality control is consistent. $22.99 for 40 oz doesn't come around often.
