I hunted deer today after a several year hiatus and conditions were terrible.
Now.....my Duofold Expedition Weight undies work pretty good, but for some reason they don't fit as well as they used to.
The shirt is too tight and the pants seem to ride "down" until I am sitting on the waistband.
This is perplexing........it's like my ass is rejecting them.
I thought of Mil-spec polypro......about $25 for a pair of the pants (same for the top).
Seems pricey for "under-britches"
