Whether your mornings are spent around a cozy campfire or en route to a new destination, Hydroflask's 16 oz Coffee Flask makes your day a little brighter — and hotter or colder depending on what’s inside. TempShield insulation keeps your cold brew icy for up to 24 hours and your chai tea latte hot for up to 6. Plus, it’s the same size as most larges at coffee shops, so you can get your caffeine fix without adding a disposable cup to the mix.
