Overview
This Iron Flask 24 oz narrow mouth bottle is a double wall insulated stainless steel water bottle with a leakproof straw lid that clips on with a carabiner, built to keep drinks cold for 24 hours or hot for 12.
The double wall vacuum design is what lets the bottle hold temperature for a full day without sweating onto a desk or a car seat. The straw lid and carabiner clip are aimed at people who want to sip hands-free while moving, whether that is at a gym or on a trail. Note that the steel body is hand wash only, so it is not a toss-in-the-dishwasher bottle.
- 24 oz capacity
- Double wall insulated stainless steel
- Leakproof straw lid with carabiner clip
- 18/8 BPA free steel
Who it's for
Suits gym goers, commuters and outdoor users who want a straw-lid insulated bottle that clips onto a bag. Less suited to anyone who wants a wide mouth for ice cubes or a bottle that can go in the dishwasher.
Pros and cons
- Keeps drinks cold 24 hours or hot 12

Performance notes
Double wall insulation is what keeps the outside of the bottle dry to the touch while the inside stays cold for up to 24 hours or hot for up to 12, according to the listed specs. The 18/8 stainless steel body is chosen to resist rust and avoid the metallic taste some cheaper steel bottles pick up.
