Pay it forward completed: a super clean pair of REI synthetic insulated kids gloves in XL size. Microfleece lining, goggle wiper on RH glove, gauntlet drawstrings with toggles. Ripstop nylon with softshell-like material on backs, synthetic leather palms. 5.1oz on my scale. $3 for First Class mail to US addresses.
According to REI chart, XL should fit to hand circumference of 8" and hand length of 7.5" age 18, so these should fit smaller adults too.
"To measure knuckle circumference, keep your hand flat and measure around your large knuckles. Do not include your thumb. To measure hand length, measure from the base of your palm to the end of your middle finger."
