The Alpine Machine Roll Top Packs

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

     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 attachment points have 6-8 lines of stitching.  All webbing stress points are fully reinforced with a second layer of webbing on the inside of the pack.

    • full strength front and rear haul loops. 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.

  • UHMWPE Fabric : Dimension Polyant DX40 five-layer laminated fabric for best strength to weight and that NASA look in white. all reinforcements are also done in this fabric. Other fabric options available on the Custom Pack Order Form.
