A couple of times a year, my hands crack pretty bad, and I don't notice how dry they are until it's too late. I'd love keep a pair or two around for when it happens. It REALLY stinks when the skin on my hands crack and I don't notice it until I'm about 20 minutes into a three-hour set.
Cracked hands reminds me of my research years where the gloves cause me to have bleeding cracked hands for about 20 years. No matter latex, vinyl, neoprene, etc the gloves would dry my hands so bad-that and washing a bunch after handling toxic or radioactive reagents. I hate gloves with a passion now.
