Corvus Adapt insuLITE 4-in-1 Down Sleeping Bag

Kathmandu offer bags in the following sizes:
  Mummy Semi-Rectangular Rectangular
Small 72cm x 197cm    
Regular 70cm x 206cm 72cm x 211cm< 76cm x 211cm
Large 72cm x 220cm 74cm x 225cm 78cm x 225cm

Mummy bags, with their wider cut shoulders and narrow feet are the most efficient when it comes to weight and warmth. These bags conform more closely to your shape and only require minimal body heat to warm up. They encase you ‘like a mummy’ and may be restrictive and less roomy than other bags.


Semi-Rectangular bags with their tapered foot (more room than the Mummy) and contoured hood are a good compromise. These bags provide ample sleeping space at the torso for comfort.


Rectangular types offer more space and are cooler than others, letting you move easily within the bag. Because of the larger top opening, heat can escape more easily.
