I've posted a few things leading up to this, but I've now completed my review of the Jetboil Sol.
The new Jetboil Sol
The new Jetboil Sol features a smaller, lighter pot in either all aluminum or in titanium with an aluminum heat exchanger. In my weighings, I found only about a 1oz difference between the two. Please see the table in my review for details. In addition to the smaller, lighter pot, both versions of the Sol feature this significantly lightened up burner with substantially improved piezoelectric ignition:
The new burner is good, but the regulator valve makes real cooking difficult. The adjustment is tricky to say the least in the lower end of the burner's range. Still, cooking can be done if one is willing to fiddle a bit.
