If my memory serves me, the red plastic bottle was 2014, the identical but gray was 2016, the metal thermos was 2018, the pandemic was 2020, and 2022 I got an identical 2018 thermos with the red logo but put a sticker with the blue logo over it.
However, my SketchUp model has this bottle labeled as 2016. Typo maybe? Does anyone remember what base camp this bottle was from?
