GSI Microlite 350 Flip: This small and lightweight thermos with screw cap is made of durable double-walled steel. The walls are 1/3 thinner than most single-walled thermoses. Despite this, it holds the desired temperature of the beverage very well. Cold for 16 hours and warm for up to 8 hours.
The thermos is great for short trips, exercise for the kids, or morning coffee thanks to its compact size and light weight. The lid opening system works on a simple hinged system, for easier handling of the thermos.
