Hi Tyler,
The weights are not set as each pack is customized for each person. but the White Light/White heat is 22 ounces as shown. The Alpine Machines are between 27-36 ounces depending on volume.
it's really the webbing and buckles that add to the weight of a pack. the fabric is 6 oz per square yard/meter. so some customers ask for 18mm web and buckles and that saves about 3 oz. axe loops save weight over the standard tool holster set up. So every pack is customized to the owner's desires. Some want a very robust sac for guiding and long alpine climbs, other want a very stripped down sac at the lowest possible weight.
please let me know if you have any other questions.
