The Jerven Bag Exclusive can be made significantly warmer and drier with the addition of zip-in Primaloft lining. Primaloft has heat retention capabilities that surpass even natural duck down, without concerns for longevity or severe loss of insulative capabilities when damp.
The Primaloft liners are available in two grades: either 60g/sm or 170g/sm. We would recommend the 170g/sm for colder extreme winter conditions whilst the 60g/sm is more appropriate for 3-season use.
Each lining comes packed in its own stuff sack, in the same camo design, so you can also attach it to the outside of your rucksack.
