GSI Outdoors MicroLite Twist
Best lightweight insulated bottle for hikers needing easy access on the go.
This is the lightest vacuum-insulated stainless steel bottle available, making it the clear choice for weight-conscious backpackers. It sacrifices some ergonomic comfort in the handle for a significant reduction in mass, proving that you don't have to choose between insulation and a light pack.
