SAIMA INSULATED

I was skeptical about the 850ml size being too bulky, but it fits perfectly in my daypack and keeps coffee steaming hot for hours. The vacuum insulation works even better than I expected, and the leak-proof lid gives me total confidence tossing it in a bag.

I was pleasantly surprised how well the tea-strainer works for loose leaf without any mess, and the vacuum insulation keeps it steaming hot for hours. Perfect for my morning commute.

This thing keeps my iced coffee cold from 6am until well past noon, which is exactly what I needed for long shifts. The tea-strainer built into the lid is a nice touch too, and I've had zero leaks even tossing it in my bag sideways.
