Nifty little gadget that Kieth Titanium put together there. I’ve never seen one or heard about it until your post.
Well, without getting too deep, I am sure it would make a tasty cup of backcountry coffee like my other pour over methods did. Without trying it myself, I would still think that it suffers from, in my opinion the biggest drawback of doing pour overs outdoors, the coffee being lukewarm by the time the coffee is ready to drink.
Additionally, even being titanium, it’s still another piece of gear to bring which would increase the total system weight. From the information I’ve found on it, it looks like it weighs over 3oz which would make my current setup come in at 11oz including 4oz of fuel, so more than double the 5oz you estimated.
Im going to take a pass on commenting about the price tag.
Thanks for pointing out this little filter. If you ever purchase one, please comment in this thread on your experiences.
