For some reason I think of it as an older concept. Now Starbucks and coffee chains are popular.

Highlighting carlcook’s advice:
dissolve in cold water, ONLY THEN add hot water. The rationale behind it is that aromatics evaporate too quickly when the instant powder is infused with too/boiling hot water.
I’ve seen 'em and I’ve used them in the past. They’re a fine solution, but they still require cleaning and a couple of satchels of Taster’s Choice or whatever is easier on the KP and also much smaller than a giant coffee syringe. Showing up at the pay-for-pitch in the station wagon is one thing, but usually all my stuff needs to either fit in my panniers or my backback.
There are guys I’ve hiked with who have them, though. To each their own.
I’m with you on this one, too. I prefer my jet boil and instant coffee (or matcha) compared to an Aeropress.
