It depends. The Standard frame, suspension and compression is 2 lbs 6 ounces. The UL frame, suspension and compression is 2 lbs 3 ounces.
Roll Top XPAC bags are generally 14 - 18 ounces depending on size and zipper. 210 Denier Tan bags are generally 5 ounces less.
Base Talons average 5 ounces, but vary a bit on fabric choice. Cuben for instance is 3.7 and Camo over 5.
Day Talons about 12 - 13 depending on size and fabric.
The configuration I weighed yesterday was a Tan 3900 with zip/ Cuben Talon / UL Frame / Large belt and it was 56 ounces, which I thought seemed heavy. Then I remembered I had a small torso pad (8 ounces) in the packbag (oops). All of these weights include the load sling and load shelf capability, and the capability to be used with a Talon or Pack bag alone to save more weight.
