I'm trying to find non-webbed thermal swim gloves for my wife. I've purchased size SMALL in Blueseventy Thermal Swim Gloves, and they are still too big. They measure up to 3.5" across hand from index finger to pinky according to Blueseventy size chart for gloves. I also looked into Xterra and Orca thermal gloves, but they're even wider at 4.0" across hand from index finger to pinky. Any suggestions on triathlon thermal gloves smaller than the Blueseventy brand in width and length? Blueseventy, Xterra, and Orca, to my knowledge do not make an EXTRA SMALL size as SMALL appears to be the smallest.
