paragliding training center
These are the gloves of choice because they have thin leather palms and are much cooler than full leather gloves. Harbor Freight, Sam's, Lowes, and Home Depot stock gloves like this.
The reason that pilots should have leather gloves is that they will not melt when the fine lines of the paraglider get pulled through them very quickly. Synthetic gloves will melt and the line will then cut the pilot's hand. How do we know this? Think about it....
