IMHO There is no 'real' way to long term carry gloves that aren't climate controlled. I regularly switch out gloves. The 2 pair I carry daily get swapped out (used) so they don't degrade. Excessive heat in FL though so they degrade more than in a cold northern climate...lol.

If you ever need a pair or two... I've never seen a medic turn down someone's request for 1 or 2 pair to 'restock their FAK.
