Don't some aviation people recommend O2 for all extended flights above

The 32F / 0C (bottom end temp range) seems odd - especially since they
recommend SportStat for mountain climbers. Use it with a big mitten?

From their web page:
SportStat can be used by a variety of sports enthusiasts, including mountain
climbers, hikers, skiers, bikers, and others interested in measuring blood
oxygen saturation and pulse rate. It can be used outdoors in many
conditions, including high altitudes, at high and low temperatures, and even
in the dark.

(Retail price - $400. I've seen them listed somewhere for about $350 this
summer)
