Sleeping bag - Everest Adventure - March/ April 2013

[sioned]

I'm booked onto the Everest Adventure trip on the 31st of March - 15th April 2013, I understand it is the very end of Winter.... what kind of sleeping bag should I buy? A minus 12 one or more or will a four seasons one be sufficient?

Also, what kind of clothing will be suitable for the evenings when we have reached the sleeping camp? What kind of temperatures can I expect?

Thank You

Sioned

Hi
I'm doing same trip end of April and I've gone for 3 seasons Down to -15 comfort. You don't sleep at base camp you sleep lower Down so should be as cold .
I was told thermal gear for when you are higher up, incl hat scarves gloves etc
