Alaska Guide Bino Harness with wind indicator and optics cleaning kit.
I usually bring my 90 mm lense.
I have successfully used Vortex & Leica.
My clothes are primarily Sitka, but I do use Kuiu, Patagonia, Outdoor Research, and/or any other light weight fabric clothing that dries quickly and is resilient.
I recommend Crispi, Koflach Plastics, and/or Bunny Boots.
I have seen a lot of different brands successfully used for bows and rifles. I do recommend a 300 Winchester/WSM/RCM/PRC type caliber due to the fact that you will often encounter bears. I personally like shooting Ruger, Tikka, and Christensen Arms builds.
