I'm going to pick up a new sleeping bag at REI in the next couple of days and I'm looking for some advice. I've narrowed my options to a North Face Tundra -20 degree bag or a Mountain Hardware Lamina -15 degree bag. I'm replacing, or rather augmenting, my Slumberjack Everest Elite two-bag system that I've had for years (35 degree bag + 0 degree bag = -10 degree bag). The Slumberjack is fine for moderate temps, but it's getting old and has lost a little something when it gets really cold. And yes, I know about Wiggy's bags. But they don't sell them at REI and probably won't take either REI's discount coupon or dividend as payment. So these are the two choices. I've tried both of them at the store and fit isn't an issue. Just wondering if anybody has any experience with either or both of these bags.
The Tundra is a pound lighter but is bulkier. The Lamina is heavier but compresses better. The Tundra is $30 more expensive and is rated 5 degrees colder. The Tundra also has some type of retaining loops sewn in along the sides. I keep going back and forth.
