EN Tested
Kelty has always tested sleeping bags to make sure that their customers are warm and comfortable on their adventures. Now they`ve adopted the European Norm (EN) 13537 test process which provides a standardized comparison method for all sleeping bag brands so that it is easier for you to choose the right sleeping bag for your needs. The two temperature ratings listed are Comfort and Lower Limit. Comfort is defined as the temperature that a standard woman (60 kg / 132 lbs) will be comfortable at versus Lower Limit which is the temperature that a standard man (80 kg / 176 lbs) will be comfortable at.

Two Layer Offset Quilt Construction
By layering two or more sheets of insulation between the liner and shell of a sleeping bag, heat is easily trapped and maintained. To eliminate cold spots, one layer of fill is stitched to the liner, another layer is stitched to the shell, and then the quilt lines are offset so they do not lie on top of one another. Offset quilt construction is durable and maintains its shape and structure after many uses.

Ecopet Insulation
Kelty supports responsible manufacturing and waste management with Ecopet Insulation:

  • Resin free construction
  • 100% recycled polyester content
  • Hypoallergenic
  • High loft
  • High resiliency

Synthetic Insulation
Advantages of synthetic fill are its ability to maintain insulating properties when wet and that it has less required maintenance than down, as well as having the potential to be recycled.
