Had a pair of the Filson, goat skin(?) gloves, paper thin, but tough as nails. After 5-6 yrs I thought they could use some conditioning. Well, I took the advise of the wrong person and used conditioner that turned the gloves into "grease rags". In an effect to remove the conditioner, I heated (hot, hot) water and submerged one glove. In about five seconds the glove shank to about 1/3rd of the original size...so much for that pair.
Anyway, while researching another item, I come across the Gieir #330 Gold ES gold, goatskin gloves. The reviews say they are thin, with a good tight fit...for $70. As Filson doesn't offer my gloves any longer, I think I'll give the Gieirs' a try.
