I have not heard about titanium kanteen type of bottles, but I recommend you check out hydroflask they are made up of 18/8 stainless have two layers with vacuum insulation I think they claim 12 hrs for hot drinks and cold for 24 hrs
I was about to order some I heard they are...
One thing I forgot to mention was that I used a sundrop with the nichia 83 led, I'll try it with a haiku next time around
But I think the engines for dons 3v are all the same except which led you choose
I tried with a surefire that locked on high I ran it down, it starts to flicker and flickers......for a long time.........lol lots of time........then once the flicker stops it eventually will only turn on at the instant you press in the switch until you hit the point it becomes a dead rock
