The criteria for quality SAR gear is high, and expensive. How much do the members have to buy, try and discard before they find what works and what suits them? A lot, I'll bet. And the good stuff is expensive.
Being a member of SAR is not a cheap endeavor. And most of the SAR people are paying for all of it themselves.
Maybe a donation to your local Search & Rescue would be an appropriate holiday gift to someone you hope you'll never have to meet.
