july 2021- the Alpine Machine packs 60-100L are all the same price. the 60L &70L models went up a little, the 100L came down. My main goal is to build the best pack for your needs and all the big packs are about equal in the time/materials required.
This is the biggest pack I currently build. It was designed to replace a customers old Dana Designs Astralplane, which was rated at 120L, but in real life wasn't THAT big.
despite it's size this pack, with it's roll top bivy closure is 3 lbs, 4 oz, the lid is 9 oz, and the alloy frame stays are 6-9 ounces depending on the final length. these weights include the sewn on front pocket, wand pockets and a ballistics nylon double bottom and lower rim.
This pack is deeper front to back, 10" on the bottom, to keep it from getting to tall. It also has much less taper, just 1.5", to make loading easier.
This pack has a big,simple, lid with a #10 YKK waterproof zipper opening. there is a full map pocket on the underside with #5 waterproof YKK zipper. it also has 2 daisy chains on the top . lid volume is 9 liters.
A few features are stock on this pack that are customer choice on smaller packs:
full custom fitting
all have the 3" curved shoulder straps.
all have a custom cut conical hip belt
1'' webbing for the harness
twin 7075-t6 aluminum frame stays
a doubled 3/8" 6 lb closed cell foam back panel, so it's 3/4" next to your back and the frame stays run on the outside of this foam panel.
