Veelgestelde vragen
Yes, tested with ice water in summer conditions. After 24 hours, ice remains solid and water stays noticeably cold. Performance varies slightly with ambient temperature—hotter environments reduce the duration slightly, but cold retention remains superior to single-wall bottles.
The brushed stainless steel finish provides reasonable grip when wet, though not textured like some competitors. It's comfortable to hold but not as slip-resistant as rubber-grip bottles.
Yes, it's effective for hot beverages too. Vacuum insulation works in both directions—coffee or tea stays warm for approximately 12 hours, though not quite as long as cold retention.
Hand washing is recommended to preserve the stainless steel finish and vacuum seal integrity. Most dishwashers won't damage it, but handwashing extends its lifespan.
