Mummy bags are warmer and lighter than their rectangular brethren, but they’re usually a lot less comfortable. They’re also more constricting for folks like me who sleep on their sides and like to stretch out. That’s where Montbell’s Down Hugger line of sleeping bags comes in. The sacks use what Montbell calls a “Super Spiral Stretch System” that gives the fabric some play and allows the bag to move with you when you roll in the night. Klymit also makes a great down bag with stretch in it that’s super comfy and a great price.
