Large Box Shaped Bag

If you’re someone who likes to roll around in your sleep or prefer extra room, the Darche Cold Mountain 1100 sleeping bag’s large box-shaped design is a dream come true.

At 2500mm long and 1100mm wide, the sleeping bag offers plenty of room to stretch out and sleep in any position you prefer. Its generous size doesn’t compromise the warmth, ensuring an even heat distribution throughout the bag.

Cotton Flannel Inner Lining

The interior of the Darche Cold Mountain 1100 is as impressive as its exterior. Lined with 125gsm cotton flannel, this sleeping bag offers an added layer of warmth and insulation.

Dual Zip System

One of the standout features of the Darche Cold Mountain 1100 is the Chilly Nights Dual Zip System. Ever struggled with a stubborn sleeping bag zipper in the dead of night? Not with the Darche Cold Mountain 1100. This sleeping bag comes with a dual zip system, allowing you to zip and unzip the sleeping bag from either side effortlessly. This not only makes entering and exiting the sleeping bag a breeze, but also allows for easy temperature regulation.

Got a camping partner? The dual zip system lets you zip two Darche Cold Mountain 1100 sleeping bags together, transforming them into a large doona. So whether you’re camping solo and need extra room or sharing the bag with a partner, this sleeping bag has you covered.
