After your sweat evaporates and cools immediate skin it was upon, is the ideal then to have that resultant vapor whisked away as quick as possible, so to be promptly replaced with new hot/dry air, or not?
Can one be expelling and replacing it too quickly, like when hot/dry windy with no shirt, then wasting some of your sweat evaporating ‘coolth’ potential?
And, if so, would it not be best, <span style=”text-decoration: underline;”>if you could do it</span>, that all sweat evaporates directly off skin rather than some getting shirt wet and then that portion always evaporates off it, often billowing away at a distance, and much of it directly cooling to the outside of the shirt being whisked away and not even to the inside of the shirt, closer to skin?
If that’s all true, then would not this be best to maximize cooling from sweat, to have it evaporate where you want and keep cooler vapor from being too quickly whisked away, replaced with hotter coming in, <span style=”text-decoration: underline;”>if it could be done</span>;
Naked, or nearly so, body under 3/4 length, just below knees, loose wind or rain poncho, that was effectively largely held away from skin, especially at top chest, shoulders and around head so incoming air from below, aided by movement, could freely circulate up all the way to and around neck and head and then exhaust out at neck and around face? Maybe adjustable slit opening in back of neck, too.
Again, <span style=”text-decoration: underline;”>if it could be done</span>, to where enough air circulated freely up and out fast enough, would that not achieve the maximum cooling per ounce of sweat, as long as it wasn’t dripping off to the ground first?
BTW, I’m thinking more for in hot/dry desert where I rarely ‘wet’ sweat anyways, where humidity often so low it evaporates too fast, shirt is never wet, just my back from pack and under belt.
Also, garment would be close to white for reflecting solar radiant heat and being wind proof, that’d cut down on hot dry wind excessively adding to internal heat load.
To aid more air more freely circulating, I was thinking a lightweight curved U of any flexible slim rod coming out a couple inches at 45 degree angle near top front of shoulder straps to hold loose poncho or wind/rain jacket both up off shoulders and out a bit in front of chest.
Anyways, tell me what I’m missing here, or why only rare occasions where it might maybe help, thus too little potential cooling gain for the effort expended. Thanks for any thoughts.
