Designed for nights of shared drinks around the campfire. The Sierra Cup makes sharing a brew from a community pot more sanitary with your own personal drinking vessel. Made from super lightweight 18/8 stainless steel with a smooth rolled lip and sturdy handle for easy drinking you won’t be able to help yourself with that second helping. The Sierra Cup holds 10 oz of liquid, while the mug holds 16 oz of liquid. Both are suitable to hold hot drinks, but not designed for heating or direct exposure to flame.
