Continuing to push the innovation boundaries, the Sea to Summit designers have created the ultimate in expedition and outdoor dinnerware. Lightweight, practical and made from durable, odor resistant, BPA-free food-grade Nylon 66. Nylon 66 can withstand high heat and cold. Both the bowl and plate feature the patented Protex hex pattern base which reduces weight and lessens the surface temperature so they can be held comfortably with hot foods or liquids inside.
