Outdoor; Started a great thread titled what have we become?

That thread got me thinking about what products are new and work well?
1) Smart wool long under wear.
2) Smart wool socks.

Both of these items are an improvement over the old "itchy scratchy" wool garments. I use both products and think they are worth using.

A tech item worth using, a GPS unit with a memory that will let you save your spots/hunts. This allows you to return to the exact spot every time and recover your game.
This also allows you to hunt the same spot when ever you return, that could be five years from now?
