Hey all, I'm looking to get a warmer bag for shoulder seasons and not spend a fortune. I'm looking on Sierra Trading Post, trying to play the coupon game. Here is what I've found -
Marmot 20°F Kenosha Down Sleeping Bag - 650 Fill Power, Mummy - 2lb 9 oz

Kelty 20°F Ignite Sleeping Bag - Long, 600 Fill Power DriDown - 2lb 15 oz

Obviously I'm favoring the Marmot at -4/-6 oz, but what is the consensus on DriDown? Both Keltys are cheaper as well. Help me decide!
