What do you have to carry.....and where are you going?
Not to totally simplify things....but thats how i am.
If you dont need to carry anything but a plinker and some plinking bb's.....wear shorts and a t shirt and put your bb's in your pocket.
If you need to carry .556, 40mm, commo, batts and all that crap....i would wear the vest.
The issues at hand are pretty simple, forget about sweat....your gonna sweat, sweat control is another topic.
What do you need to carry, and what is the most effective way to carry it. Your comfort isn't gonna come from sweat or not, its from how well the weight carries.
When you carry weight in an LBE all the weight is hung from your shoulders. Additionally, all the weight from your ruck is riding directly over those very same shoulder straps.
When you carry weight in a vest, the weight is more evenly distributed, and much of the weight is carried by your hips rather than shoulders.....and there is less conflict with your ruck.
When you patrol, as opposed to drive up, dont wear anything on your legs. You dont need any drop anything on patrol. You need your legs.
Only carry what you need. Nothing wrong with an empty pouch.
When its hot, i fill my empty pouches with frozen juice boxes when i start out.....
Its REALLY good in the desert. Put frozen juices in your admin pouch. They keep your heart, and therefor blood cool, and are yummy when they melt.
Need a friend quick? Give someone in a far away land a half frozen juice box out of your pocket and see how quickly they become your pal.
