7.62,
I walk pretty deep into hilly public land carrying my gear and climber also. Generally, i will hike in with the lightest possible clothing on (even when very cold)
When i get to the tree, i let myself cool down some, take the clothes off, put them in a large ziplock wipe down, spray down and start slowly putting on the hunting clothes a layer at a time so as not to get over heated again.

I also walk in very slowly and leave plenty of time to be up in my tree settled in and ready to hunt 1 hour before light. I know that takes getting out there pretty darn early but that's how i do it
