I own both the fanatic and the Klamath, Even though I mainly wear my Firstlite gear the majority of the time, I love the fanatic. I find with most of the gear from both brands, I like the Firstlite to actually wear, even though I love the functionality of the Sitka gear. I think Sitka is more thought out and has a lot of useful features, but I love my Firstlite merino and other gear. I actually wish Firstlite put more thought into that aspect. I love the mittens in the fanatic hoodie, the integrated mask and the pouch.... Normally when sitting in the tree stand, if I start to get a little cold in my fingers, I’ll just fold over the mittens and occasionally pop the, into my pockets to take the chill off. I own almost every piece from both first lite and Sitka, but other than the fanatic hoodie, I find myself consistently turning to the Firstlite gear
