Sea to Summit’s X-Series has been an extremely popular and comprehensive range of collapsible dinnerware for years. The fundamental appeal of these items is how compact and functional they are. Now, Sea to Summit has extended those concepts to cookware with hard-anodized aluminum bases that allow camp stove cooking. The beauty is how they collapse and nest with our dinnerware and other X cookware, creating the most compact cooking and eating sets you’ll find. There are five set options suited to just about any activity and group size.
