Alpine Luddites

Alpine Machine 60 & 70 Liter packs


AM70 on Mt Everest.


The Alpine Machine 

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. 

The 60 & 70 L packs differ from the Machine packs in several ways; They are all larger in volume. They have the option for a bigger removable, fully padded hip belts and shoulder straps, more appropriate for carrying big loads than pure climbing packs. The volumes can be customized even larger than 70L if needed.

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, but no frame sheet to save half a pound. We sort exactly how you want your pack set up, during our phone call, once you order the pack.

    This pack is available custom sized back length and hip belt.  There is no extra charge for custom fitting.

    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 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.
