Insulated performance in an uninsulated-sized package — GSI's Microlite is the pick for hikers and backpackers who refuse to sacrifice cold retention for weight savings.
Most people haven't heard of GSI, but backpackers know. If weight and pack size matter to you, nothing else comes close to this combination of insulation and compact form factor.
“I really like GSI microlight bottles. Insulated well, but the same size and weight as uninsulated bottles. Very durable too.”
