In reply to Dutton:
I can't imagine crack gloves are a product that are sold in particularly large volumes - a higher profit margin per item is probably needed to make the business viable for a niche item, sold to a fairly small potential market, than for other outdoor kit.
Plus, having worked in outdoor retail in the past and seen the margins on most technical clothing, for example, I don't think crack gloves are the thing to worry about - the manufacturing cost of a lot of outdoor clothing is peanuts compared to the sale price!
