I started using Sitka Gear last season. I mostly like the material and design (pockets, zippers, fit, durability, etc.). The pattern is at least as good as anything else.
Of course we aren't just trying to go undetected by the deer we hunt. Its also to our advantage for the turkey, jays, crows, etc. to leave our presence unannounced.
While it's been known for a long time that birds see colors well (that's why many male fowl are so colorful) research is showing that deer and other mammals detect color differences better than thought, especially blue.
I certainly agree though the very best clothing in the world can do little to hide quick or constant movement. If I feel invisible, I act invisible.
I won't do Scent Lok.
