The Universal Stainless Steel Cup Lid fits all the cups on the market that fit the Standard 32oz - 40oz Nalgene Bottles and the Widemouth Stainless Steel Bottles, such as the Klean Kanteen. So far we haven't found a Cup that it doesn't work with, including the Olicamp Space Saver cup and Vargo BOT. If your cup fits a Nalgene or Kleen Kanteen Bottle whether it is tight fitting or loose fitting this Lid will Fit! Designed by our good friend, Rob Simpson at Lost Wild Outdoors, it is made from High Grade Stainless Steel and you won’t bend this lid. It is so rugged you can use the edge of the lid to strike a ferrocerium rod, and has no moving parts. Made in the USA, unlike every other cup lid out there. The lid measures 4 3/16" over all in diameter, the inside "hub" is 3 11/16" and it weighs 1.6 oz.
