That was an XLNT Review! I was trying to come up with a Multi-use for the Heavy Cover,to justify it's means over Alum.Foil,Not to mention Where on a Canteen Cover,Is it going to be Stowed? or Is that the Next $20 item in line for this Set-Up,A Possibly extended Canteen Cover,to allow for the HeavyCover to fit on the bottom,of the canteen cover!Possible other use's for the Heavy Cover:Bacon/Burger Press,Bug/Scorpion Smasher,Cowbell alternative for Gitfiddle Campfire Tunes,Sear Plate for cauterizing wounds,Set on edge in the dirt/sand for use as a Multiple Launch Platform for Bottle Rockets,or Incense holder for Spiritual backcountry shindigs????
