The Sea to Summit Sigma Cookset 2. 1 allows you and your companion to enjoy a great backcountry meal. The marine-grade stainless steel pot has a strainer lid and a graded scale on the side of the pot for cooking convenience. Afterward, the pot is easy to clean thanks to its abrasion-resistant polished construction. The mugs are also easy to clean with their removable insulation sleeves and silicone sipper lids. After the meal, the bowls and mugs nest inside the pot and the pot's Pivot-Lock handle locks the lid to contain the complete set for convenient packing.
