On this episode, I talk with John Barklow, Big Game Product Manager for Sitka Gear. John was a huge part of helping me understand layering systems and inspiring me to test out different combinations in a variety of settings and weather conditions. His extensive military training experience along with many big game hunts has inspired him to build some of the best clothing in the world.
