Knitted wool, for the most part.
Cavalry Gauntlets, as well - but not commonly - and those were often beaded, when near a Fort.
Leather gloves were available via the Mail Order Houses - check any of the reprints of the pre 1899 'Sears, Roebuck & Co' and 'Montgomery Wards Co.' catalogs, and you'll see little, if any difference in styles.
Elastic wasn't in play though, so look for a tight knit at the wrist.
Vaya,
Scouts Out!
