Since I’m oldschool I deliberately bought one of these with a cork instead of the plastic cap, from the Auckland store. Love the felt cover and classic leather harness, it feels right at home with my bushwalking kit back in Perth. The quality of the aluminium bottle is also top class. The Czechs (or Slovaks) did a great job producing this bit of kit in the 60’s, so much so that it was used till the 1990’s! Cheers, Rafski
