Ensuring Your Most Important Gear Stays Dry
Your sleeping bag is the only place you can truly get warm during a Mount Everest expedition. Keeping the 'loft' (fluffiness) of the down is essential for surviving the cold nights near the Mount Everest summit.
Your breath creates moisture. If the down gets damp, it loses its ability to trap heat. Always air out your bag in the sun at Everest Base Camp whenever possible during your Everest trekking trip.
Every evening, give your bag a vigorous shake. This redistributes the down, ensuring there are no cold spots when you settle in for the night before your Mount Everest summit push.
Only stuff your bag into its sack when you are moving. Constant compression damages the feathers, reducing the insulation value needed for a high-altitude Mount Everest expedition.
A warm bag means a rested body. Treat your sleeping bag with care to ensure it protects you all the way to the Mount Everest summit region.
