I have a pair of gauntlet rain glove covers from Aerostich, http://www.aerostich.com/clothing/gl...n-glove-covers. I also found then by Frogg Toggs after I purchased them from Aerostich, https://www.froggtoggs.com/pilot-frogg-storm-gauntlet/.

They take a while to get use to wearing but they worked great, easy to store and also helps keep hands warm.
