Alpine Machine 60 & 70 Liter packs


AM70 on Mt Everest.


The Alpine Machine 



july 2021- the Alpine Machine packs 60-100L are all the same price. the60L &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. 

Light and Tough. Just what you expect in a pack designed for expeditions, alpine climbing or multiple seasons of guiding. Like all the packs built at Alpine Luddites, I expect this to hold up to 100's of days in use.

After you order a pack I'll contact you for your waist belt size and any customization. You can choose from all features: waist belt, harness size, bivy pad, frame sheet, alloy stays, crampon and ice tool attachment, webbing color and size, fitting issues, etc. 

Pack Volume & Unique Features:

60 & 70L, plus a tall bivy extension and floating lid. Guides overstuff these packs.  The rope strap secures gear with or without the lid. The lid straps are removable from the front of the pack. Some of my customers buying this pack for climbing at high altitude are going with a single stay. We sort exactly how you want your pack set up, during our phone call, once you order the pack.

sizing notes:

  • all packs are custom fitted. please refer to custom pack order form.
  • sizing notes: for sizing, I'll need your waist size in just a shirt. for back length measure from where you want the bottom of the pack to sit to the top of your shoulder. If you plan to wear this with a harness on and climb wearing the pack, measure from where you want the bottom of the pack to sit in relation to your harness to the top of your shoulder. For normal mountaineering use I'll need the length from where you like your pack to sit on the bottom edge of your back to the top center of the shoulder, but don't wrap the tape over your shoulder. Our padded Alpine hip belt is 3.5" wide, narrow enough to allow you to lift your legs while postholing but wide enough to help transfer some of the load. It's fully removable for climbing.

Construction: this pack is built with only two main seams that attach the two body panels together. There is no need to worry about blown stitching either. all seams have multiple passes at 8 -10 stitches per inch. compare that to most mass produced gear. All seams are taped for durability.  All webbing stress points are fully reinforced with a second layer of webbing.


    • Two-pocket lid, one on the underside. Fully removable from any position. can be purchased later if it gets trashed or lost.
    • roll top bivy extension is made out of Xpac VX21. this fabric is waterproof to 200 psi. sleeve length 12".
    • Weight-38-48 ounces depending on volume and features, but as each 
    • sizes: both stock and made to measure back length, waist belt, and shoulder straps.
    • closed cell foam back pad
    • removable padded hip belt. 
    • Ice tools & crampon patch reinforced with the 2nd layer of fabric. 
    • full strength front and rear haul loops. the front loop is reinforced with a layer of 2" nylon webbing sewn onto the inside of the pack. Haul points are sewn on top of this to spread the stress out onto the entire front of the pack, not just into the stitching.

    • rope strap.
    • UHMWPE Fabric: Dimension Polyant five layer  Laminated  DX40 fabric for best strength to weight. Other fabrics are available, please refer to the custom pack order form.
