First Lite make a jacket/jumper hybrid (the Sawtooth), a soft shell (North Branch), a range of puffys, and two rain jackets.
None of these are the exact same material as the Kanab / Obsidian pants though ... they did once make a top layer out of the same fabric, the Chugach 'work shirt'. Some of us think it's the shizzle, and wish that FL would bring it back: it's quiet, stronger than standard interlock merino, can be partially opened with the buttons and no fear of zipper failure, and had a small amount of wind resistance. This shirt could be worn simply as a shirt, or as a very light jacket over other layers.
Maybe with Sitka's current line about 'with other brands, you're hunting in your underwear', First Lite will reconsider the need for a more robust shirt option, and bring the Chugach back to production.
However, in the current line-up, the closest you'd get in material is probably the Sawtooth - but you'd need to decide whether it would be too warm for your uses.
for early season I like the llano and the chama and then the halstead...for early season the layers work best. fl is releasing a sawtooth which could be used instead of the halsted and is bulkier...hope this helps
