I own a lot of gear from both as they are both my favorite. kuiu is my on the move, spot and stalk, or earlier season attire. Sitka imo, can not be beat for stand hunting or colder weather (sub freezing). Sitka is quieter, warmer, and patterns nicely for late season western hunting. Kuiu is light, tough, and great for trekking the mountains. Again both great products, just my 2 pennies..
